1:36

new studies

1:47

advanced technology

1:51

examination. There are several important

1:54

things which makes physical examination

1:56

still fashionable in 2020. I will

1:59

mention two of them

2:02

and physical examination is a cheap

2:05

technology. It's a lot technology but

2:07

it's a cheap technology. So it can be

2:09

repeated several times without adding a

2:11

financial burden institution.

2:15

But more importantly

2:20

physical examination if done prudently

2:23

done successfully it will help you

2:26

selected appropriate investigations.

2:32

I belong to a school.

2:37

You try your best by physical

2:39

examination to reach a final diagnosis,

2:43

a semi-final diagnosis or at least a

2:46

very narrow differential diagnosis and

2:48

then you choose the appropriate

2:50

investigations and you see whether the

2:52

results of the investigation is matching

2:55

results of your clinical examination or

2:57

not. If not, this means that you need a

3:01

further work up. Let me give you an

3:03

example. You examine a patient, you come

3:06

to the conclusion that it's a tight

3:07

micro stimosis. But you do an echo and

3:10

the echo reveals that it's a mild mild

3:12

or moderate mital stimosis. then

3:15

probably you need to exercise the

3:17

patient or look at a different method by

3:19

calculating the mital valve area like

3:21

continuity equation like or you might

3:24

need a three-dimensional echo to map and

3:27

find out the mital orifice in a very

3:30

realistic way so that's the importance

3:32

of physical examination it will never be

3:35

up outdated so I will take you to the

3:38

first year of the medical school the

3:40

cardiac cycle the cardiac cycle is the

3:43

iconic diagram

3:44

of cardio and it was put in this way by

3:48

Carlo Wigger. Carl Wigger was a founding

3:51

editor of circulation research and he

3:54

was considered because of that or

3:56

essentially because he could collected

3:58

the various stages of cardiac activity

4:00

into this diagram because of that he was

4:03

considered the dean of American

4:05

physiology. So it's very important. I

4:08

know that you are very well acquainted

4:10

with the different phases of the cardic

4:12

cycle. But let me point out four

4:14

important points. First of all, this

4:17

point in the left downward corner of the

4:20

diagram. At this point you will have

4:24

elevation of the left ventricular

4:25

pressure. It exceeds the left atrial

4:28

pressure and in this way the mitral

4:30

valves gets shut. Now spectral analysis

4:33

of the heart sound revealed that the

4:35

energy produced by shutting the mital

4:37

valve is not an enough explanation for

4:41

oscultating the first sound. There must

4:44

be a higher energy. So as a result of

4:47

that experiment experimental

4:49

investigators

4:51

proposed the following theory. If you

4:54

would have the mital valve sh shut then

4:58

the base of the heart will be moving

5:00

towards the apix. The apex is usually a

5:02

fixed structure in the in the heart and

5:04

the mobility of the heart and the

5:06

contraction of the left ventricle is at

5:09

partly because of the descent of the

5:11

base. So the blood is moving from the

5:15

ventricular cavity towards the outflow

5:17

tract but it meets a surprise

5:20

surprise

5:22

meets the descent of the base of the

5:24

mital of the mital ring the mital ring

5:27

towards the the moving blood. So the

5:30

blood decelerates and this deceler this

5:34

this deceleration puts into vibration

5:37

what we call the closed cardiohemic

5:40

system. What's that? That's the heart

5:43

and the blood contained in the various

5:45

chambers and it is this of the closed

5:49

cardio

5:50

system is what is responsible for the

5:53

generation of the first sound. As a

5:56

matter of fact, this closed theory

5:58

hypothesis proposed by Rashimmer several

6:01

decades ago is the most accepted, but

6:03

it's still a theory. So you might get

6:05

some violations of this. Now after the

6:08

left ventricular isolomic contraction

6:10

period elapses and it exceeds the

6:13

diastolic aortic pressure, the aortic

6:16

valve the aortic valve opens and this is

6:19

a soft opening. You never hear it and

6:21

then ejection continues. And the second

6:23

point I wanted to call your attention to

6:25

is this point the start of the

6:27

isopolomic relaxation phase which is co

6:31

which coincides with the dicrotic notch

6:34

of the aortic box. Now at this moment

6:37

the aortic valve the aortic valve and on

6:40

the right side the pulmonary valve but

6:41

there is a market difference that we

6:43

will come to very soon. the aortic valve

6:46

closes and this generates the second

6:49

heart sound. But again, it is the

6:51

deceleration of the blood in the aorta

6:54

that's going back towards the closed

6:56

aortic valve that puts the cardioic

6:59

system into vibration and this is

7:01

responsible for the generation of A2 on

7:04

the right on the left side of the heart

7:05

and P2 on the left side of the heart

7:08

with something in between called the

7:10

hang out interval that I'm going to

7:12

explain very soon. Now as the isopolomic

7:16

relaxation phase continues it drops

7:18

below the left atrial pressure the mital

7:22

valve opens and then active relaxation

7:25

in the normal heart brings the left

7:27

ventricular pressure curve sub zero

7:31

and this is the rapid filling phase and

7:34

then we get a diastthesis corresponding

7:36

to that the left at empt its blood and

7:40

produces the wid descent and remember

7:43

this point because This point has

7:45

deserved very little attention in the

7:48

previously but we will detail many

7:51

important points about it. Now the third

7:53

point that I want I wanted to call your

7:55

attention to is the this point this

7:59

point is lead the history where the

8:01

Awave produces elevation of the left

8:04

arterial pressure and pushes the blood

8:06

into the left ventricle and this

8:08

generates the fourth heart sound. So the

8:11

first heart sound occurs at the

8:13

beginning of the isobolomic contraction

8:15

period. The second heart sound

8:17

particularly A2 will come to P2 very

8:20

soon occurs at the beginning of the

8:22

isobolomic relaxation period. The third

8:24

heart sound is produced by the fall of

8:27

the blood from the left atrium being

8:30

sucked into the actively relaxing left

8:32

ventricle and this causes resonation of

8:35

the blood inside the left ventricular

8:37

cavity and this produces S3. Now, as you

8:40

see from this diagram, I put S1 and S2

8:43

at a higher level than S4 and S3 because

8:47

the the vibrations and the intensity of

8:50

the first sound and the second sound far

8:53

exceeds the dull quality of the S4 and

8:56

S3. You hear that with the frame of the

8:58

stethoscope. You hear that by the bell

9:01

of the stethoscope. Now h having said

9:03

that I embedded usually many uh

9:07

questions in the presentations all over

9:09

the course and these questions are very

9:11

simple question. They are not intended

9:14

to to examine the the scientific

9:18

knowledge of anybody but they are

9:20

usually

9:21

embedded here to keep you engaged into

9:24

the discussion that follows the

9:25

question. So this simple question says

9:27

that classic corroted findings in severe

9:29

aortic reg is associated with pulsus or

9:33

commands pulsus ppherians pulsus

9:36

parasardus and bifid corroted pulse.

9:39

Obviously what I am looking for here for

9:41

severe aortic reg is pulsus pisperience

9:44

and this sets the stage for details

9:48

about the coroted position. Now in the

9:51

years past we used to palpate the the

9:54

the arterial pulse and talk about the

9:56

different forms of palpatory findings in

9:58

the coroted or the radial or the

10:00

brachial or the femoral or other

10:02

positions. But now we know that we see

10:05

the arterial positions. If you are in

10:07

the CCU and you have an intra arterial

10:10

canula, you see on the monitor the

10:11

arterial pulsations. If you are in the

10:13

Kath lab, you see the arterial

10:15

pulsation. And hence you need to detail

10:18

the morphology of the arterial

10:19

pulsations and you will get some benefit

10:22

of that in both palpating and inspecting

10:25

the pulse wave for. Now as you see here

10:28

the normal coroted pulsations here there

10:30

is an upstroke called the anacrotic

10:33

limb. The steep of the of this upstroke

10:36

if it is more steep it means that the

10:37

left ventricular contractivity is okay.

10:40

So if you have a shocked patients in the

10:42

CCU and you find that this is sloping

10:44

this way then you give him inotropic

10:47

agents it moves to this way then you

10:49

achieving your target and then this

10:51

moves it to the uppermost part of the

10:54

pulse wave here which is called the

10:55

tidal wave the blood gets ejected from

10:58

the heart and gets reflected from the

11:00

upper part of the body. the bifurcations

11:02

of the vessels in the upper part of the

11:04

body and the peripheral vuscular

11:06

resistance in the upper part of the body

11:09

and this will get reflected during

11:11

history. This is the percussion wave.

11:13

This is the tidal wave and then you get

11:16

in the

11:19

end of ejection you get recoil of the

11:22

aorta and this recoil of the aorta will

11:25

produce the dicrotic wave following the

11:28

dicrotic notch caused by chlor of the

11:30

aortic band. Now this dicrotic notch

11:34

this dicrotic wave is the outcome of two

11:36

things. The recoil of the aorta which

11:38

will be impaired if you get aortic

11:40

across calcification etc etc and the

11:44

reflection of blood the blood from the

11:46

lower limbs and the bifurcation of the

11:49

superficial femoral the profound and so

11:53

forth you get a reflection from this.

11:56

Now after that you get a descent a

11:58

smooth descent of the flow of the blood

12:01

of the pressure of the blood as the

12:03

blood moves towards the peripheral. Now

12:05

so long as you get a normal vascular

12:08

resistance this is the slope. If you get

12:10

a low peripheral vuscular resistance

12:13

like in certain forms like for example

12:15

in septic shock this will be very steep

12:18

like that. If you get a high vascular

12:21

resistance this will be almost

12:23

horizontal like that. The area between

12:26

the anacrotic limb and the dicrotic limb

12:28

corresponds to the stroke volume. So the

12:31

wider

12:33

sorry

12:34

so the wider the pulse wave form here

12:37

the the the better the stroke volume. So

12:40

these kind of information if you if you

12:42

you observe it in the CCU or in cath can

12:45

give you a lot of informations which

12:48

cannot be get which you cannot get

12:50

easily without understanding the pulse

12:52

wave for. Now the question was about the

12:55

kind of the pulses. This is a pulse of

12:58

of one of the commonest revival diseases

13:01

at least in America

13:03

the commonest devel.

13:06

And what happens here is that because of

13:09

the obstruction you get a less slope of

13:12

the ascending limb. You get pulsus parus

13:14

because the amplitude is less than

13:17

normal. So it is pulsus barbus and the

13:20

apex or the peak of the pulsation is

13:22

So it's retardus as well. How

13:26

can we find out that it is by

13:28

oscultation? So this this is a what we

13:31

call reverse timing. Usually we time the

13:33

oscar we findings by palpating the

13:36

corroted pulse or the any other central

13:39

pulse but actually in under certain

13:42

circumstances we do it in the reverse

13:44

way. So this is one of the few

13:46

circumstances in which we time the

13:48

palatory findings by Oscar. So as you

13:51

see here in normal pulse you get the

13:53

peak of the pulse in the first part of

13:55

cy first one/3 of cy three but in pulsus

13:59

paras andardas you get the peak of the

14:01

pulse in the terminal part of cy.

14:04

Now as we move as we move towards the in

14:08

answering the question which we asked

14:10

this is the pulsa specificance. The

14:12

pulserence occurs in aortic grip

14:15

upstroke or anacrotrotic limb. You get

14:17

two peaks in one one of the peaks is the

14:21

tidal volume and the other percussion

14:23

percussion wave. The second is the tidal

14:25

wave. Remember and notice that these two

14:29

waves are systolic events. And because

14:32

of the peripheral vaso dilotation, the

14:34

descending limp will be more steep. As

14:36

you see, it's more steep in comparison

14:38

to normal. And the dirotic notch will be

14:40

lower down here. Since the pulmonary

14:43

artery pressure is lower than the aortic

14:46

systemic pressure because of the

14:48

pulmonary vascular resistance is much

14:50

lower and the pulmonary compliance is

14:52

much higher. Then you will find that the

14:54

dirotic notch of the pulmonary

14:56

circulation is lower than the dicrotic

14:58

notch in the systemic circulation. If

15:01

you look this is the systolic blood

15:03

pressure. This is the diastolic blood

15:05

pressure. This is the closing pressure

15:08

and in the systemic solution the closing

15:10

pressure is one/ird down the pulse

15:13

pressure and there is something called

15:15

the proportional pulse pressure. What's

15:17

the proportional pulse pressure? It's

15:19

the pulse pressure divided by the

15:21

systolic blood pressure. And what's the

15:23

importance of that? If you get this

15:25

ratio less than 25%. If the pulse

15:28

pressure divided by the systolic blood

15:31

pressure is less than 25% it cones that

15:34

the cardiac index is low below 2.2 L per

15:39

square meter body surface area per

15:40

minute. Now this pulserience is

15:45

completely different from the bacterian

15:46

pulse or the spike and the dome pulse or

15:50

the dome and the dark parts. This is are

15:52

different descriptions for the pulse of

15:54

hypertrophic card. This is the

15:57

percussion wave and this is a second

15:59

wave. This is not a tidal wave. And in

16:01

between you get the obstruction of

16:02

hypertrophic obstructive cardiammyopathy

16:05

from the opposition of the anterior lip

16:07

to the mal against the sector. But under

16:10

this circumst circumstances there is no

16:13

peripheral vascular dilation. So as you

16:16

see here the drotic limp will come

16:18

decently down not as steep as what what

16:21

occurs here.

16:24

Now another form of pulse is pulsus

16:26

alternance. Pulsus alternance occurs in

16:29

advanced heart failure provided that you

16:32

are palpating it in a patient with

16:34

regular sinus rhythm and a at a normal

16:37

heart rate. Remember that in supra

16:40

ventricular tachicardia you got you get

16:42

process alternates but this is not a

16:46

manifestation of heartbeat. It's a

16:47

manifestation of supra ventricular

16:49

ticard. So you need to diagnose process

16:52

or lens as a manifestation of heart

16:54

failure. You need to get sinus not

16:57

atrial fibrillation and you need to get

17:00

normal heart rate. But if you find it

17:02

it's called the death the death rattle

17:05

of of the heart. So this is a terminal a

17:08

very ominous sign of a very ominous sign

17:11

of heart failure. What you feel by your

17:13

fingers is a strong alternating with a

17:16

weaker pulse. So this is a bad sign in

17:19

patients with heart failure. Now we move

17:21

to another form of pulsa abnormality

17:23

pulsus paradoxis. Now this is very

17:26

important. It's a sign of cardiac

17:28

tempon. It's not a sign of constrictive

17:31

picarditis. It is it's rarely

17:34

encountered in constrictive picarditis.

17:36

And if you find it in constrictive

17:38

pericarditis probably it's an eusive

17:41

constrictive pericarditis rather than

17:43

guarded variety normal type of

17:46

paricarditis. So what do you find? You

17:48

find a decrease in the stroke volume in

17:51

the systolic blood pressure in the pulse

17:53

wave amplitude during inspiration. And

17:56

why is that? Under normal circumstances,

17:59

you get a normal fall of the blood

18:01

pressure less than 10 mm of mercury. But

18:04

in in cardiac temponet, if it if it

18:07

reaches 15 mm of mercury, you will feel

18:10

it in the brachial p. If it reaches 20

18:13

mm of mercury, you feel it in the radial

18:16

pulse.

18:17

Previously we used to calculate the

18:19

degree of pulses paradoxis by using the

18:21

spig monometer. No longer that's

18:23

required. If you feel it in the brachial

18:26

you know that it's the pul the degree of

18:28

pulses paradoxis is 15. If you feel it

18:31

in the radial you know you are above 20.

18:34

What's the cause of that?

18:37

This is what we call dissociation

18:38

between the intrathoracic pressure and

18:40

the intracapetary pressure. The intra

18:42

left side of the heart capillary

18:44

pressure. So if you have pericardial

18:47

eusion that's a protection that's a

18:49

shield between what happens in the

18:51

pulmonary circulation and what happens

18:53

in the left side of the heart. You take

18:56

a deep breath the intrathoracic pressure

18:59

gets more negative. This is freely

19:02

transmitted to the pulmonary

19:03

circulation. Essentially the pulmonary

19:05

veins the flow into the left side of the

19:08

heart decreases and the stroke volume

19:10

decreases. Now if you don't have a

19:13

dissociation between what happens in the

19:15

intrathoracic cavity and in the intra

19:17

ventricular cavity you don't get pulses

19:19

or alternates although you might be

19:22

having a strictive phys

19:26

right ventricle infuction and right

19:28

ventricle inction the right ventricle

19:30

suddenly dilates gets restricted by the

19:33

paricardium as a result of that you get

19:35

a constrictive or a restrictive

19:37

physiology but no pulsus paradoxes and

19:40

this pulsus paradox toxics does not

19:42

occur. Why? Because there is nothing to

19:44

dissociate the intrathoracic negativity

19:47

from the intra capabilary pressure. Now

19:50

this is it's it's important to realize

19:53

that this is not a sign of of conricted

19:56

pericarditis. It occurs only in 15% of

19:59

patients with constricted precarditis

20:02

but occurs in the majority of cases of

20:05

cardiac template.

20:07

Now in 2020 probably inspection of the

20:11

jugular venus proxation is at is is is

20:14

one of the most important findings in

20:17

cardio cardiovascular physical

20:19

examination if not the most important.

20:21

Now I wanted to call now this is again

20:24

wiggers diagram but on the right side of

20:26

the heart this is the right antrial

20:28

pressure this is the right ventricular

20:29

pressure you get two positive waves and

20:33

you get two negative waves. Now I know

20:36

that you know a lot of information about

20:37

that but I wanted to call your attention

20:39

to two points. Number one the X descent

20:43

and number one the needle of the Y

20:45

descent. Now the X descent what happens

20:48

here the right ventricity contracts. It

20:51

shortens it pulls the base of the

20:53

tricusp the tricuspid ring or the base

20:56

of the right atrium downward. So the X

20:58

descent the depth of the X descent is a

21:01

test of right ventricular function. We

21:03

are always wondering about how can we

21:06

measure the right ventricular function

21:07

in the appropriate way. This is one

21:09

physical sign that's really helpful in

21:12

this context. You get a deep extent.

21:15

This is corresponding to the Pepsi in

21:18

the echo cardiogram. So this is the

21:20

physical sign which tells you about how

21:23

there is longitudinal strain or

21:26

shortening of the right ventricle. The

21:28

deeper the X, the more appropriate the

21:31

right ventricular function. Now then you

21:33

get the filling of the right atrium

21:35

during the vent during

21:39

isometric relaxation period of the right

21:41

ventricle the triricuspid valve opens

21:44

the white center occurs and then you get

21:46

this period of diastasis. This is

21:49

important because of what because you

21:52

many patients with heart failure get

21:54

elevation of the general ravenous

21:55

pressure.

21:57

Now at the end of the Y wave this is

22:01

corresponds to the filling a pressure of

22:03

the right ventricle. As a matter of fact

22:05

cardiologists are very obsessed by

22:08

finding the filling pressure of either

22:10

ventricle because filling a pressure

22:12

will tell you about the function of the

22:14

corresponding ventricle and is also

22:16

responsible for the symptomatology. If

22:19

you get elevated left ventricular

22:21

feeling pressure, you get dysmia and

22:23

this is symptomatology or you get

22:25

manifestations of rightsided heart

22:27

failure if you are talking about the

22:28

right side of the heart. But what's the

22:31

filling pressure? People have divergent

22:33

opinion. Is it the end the the post

22:36

awave pressure? Is it the pre-awwave

22:39

pressure? Is it the early diastolic

22:41

pressure? Is it the mean pressure? The

22:44

majority of people are proponents that

22:47

it is the mean pressure. Now the main

22:49

pressure is this segment actually. So

22:51

when you never whenever you have a

22:53

patient with heart failure and you

22:56

diarase him you need a jugular venus

22:59

pressure to drop to drop to which level

23:02

to to drop to a level of 6 to 7 cm of

23:06

the neater of the Yave. You don't look

23:09

for the mean jugular venus pressure. You

23:12

look for the nater of the Y wave because

23:14

that's the failing pressure of the right

23:17

ventricle in most authorities opinion.

23:21

So as you see on the in the veins you

23:23

can get awave you know the various

23:25

causes of elevation of the Awave you

23:27

know the various causes of elevation of

23:29

the Bwave but I like to draw your

23:31

attention of the to the importance of

23:33

the x descent and the importance of the

23:35

wide descent and the importance of the n

23:38

of the wide descent. Now let's use this

23:41

u information and looking at these

23:44

different diagrams. Sorry for the

23:46

quality of the diagrams but it will make

23:48

the points that I wanted. It will

23:50

illustrate the points that I wanted to

23:52

make. Now this is the jabular venus

23:54

special in patients with constructive

23:56

per x descent is deep why it's deep

23:59

because the mioardium is healthy. So if

24:02

you have a healthy mioardium you get a

24:04

good descent of the base of the right

24:06

atrium or the tricuspid ring and then

24:08

you get a good exent. The fourth common

24:11

cause of constructive pericardis

24:14

nowadays is radiation following other

24:17

causes like idiopathic pericarditis

24:19

tuberclois the common cause worldwide

24:21

and viral pericarditis. Number four is

24:24

radiation periods particularly in

24:26

patients being iterated by radiotherapy

24:29

for cancer breast and particularly for

24:31

leftsided cancer breast where the heart

24:33

is immediately below the the radiation

24:38

beam

24:39

in radiation pericarditis radiation

24:42

affects almost every structure of the

24:44

heart affects the paricardium the

24:45

mioardium the endocardium the valves the

24:48

conduction system and the per and

24:50

coronas

24:51

so under this circumstance senses you

24:53

get pericardial constriction but you get

24:55

macardial affection. Under these

24:57

circumstances the descent will not be

24:59

that deep and during the rapid filling

25:02

period the heart empties the left atrium

25:05

empties into the left ventricle

25:06

unimpeded because the shell of the

25:09

paricardium at that time is not

25:10

constricting the heart the area the area

25:13

of rapid period is intact. So you get a

25:17

deep Y descent. So a deep X and deep Y

25:20

not known to every one of you it's a

25:22

sign of constriction but this white

25:25

descent is not as free as this as you

25:29

can see here in patients who stamp on it

25:32

in pericardial eusion you can imagine

25:34

the situation as if there is a rubber

25:36

band around the left ventricle

25:38

preventing it from relaxing effectively

25:41

right from the beginning you don't get

25:43

emptying of the left atrium into the

25:45

left ventricle freely as an obstriction

25:48

And as a result of that the Y descent

25:50

will not be as deep as in it's going to

25:53

be a shallow Y descent. But the X is

25:55

deep. Why the X is deep? Because this is

25:58

again is a pedicardial disease is not a

26:01

micardial disease. Right ventricular

26:02

function is intact. So get a deep Xcent

26:05

and a shallow center. Now if you get a

26:08

restrictive cardiammyopathy the X is

26:10

shallow because a longitudinal

26:12

shortening of the right ventricle is

26:13

impaired here in contrast with

26:15

constructive pericotitis and you get a

26:18

prominent Vwave with triricuspid this is

26:21

very well known to every one of you but

26:24

I wanted to call attention to most of

26:26

the young doctors to the follow most

26:29

most most cases of tricuspid regation

26:32

particularly in absence of permanent are

26:35

silent you don't hear a murmur or you

26:38

hear a very soft murmur on which too

26:41

many specialist divergence of opinion.

26:44

So how can we detect it by looking at

26:46

the neg. So the main side the main sign

26:50

of tricuspid the gauge is a prominent

26:52

Bwave and the intensity of the tricuspid

26:55

regge is judged by the elevation of the

26:57

Bwave and it's important to realize that

27:01

the absence of murmur on the tricuspid f

27:03

doesn't mean anything doesn't exclude

27:05

tricuspid regularly

27:08

if pulmonary hypertension is not

27:09

existing but even if it is existing and

27:13

even if pulary hypertension is is severe

27:16

you get absence of the Awave and at the

27:19

fibrillation and you get canon

27:21

awesiation.

27:24

I give him an example here ventric card

27:26

but heart block is another example but

27:29

let me add to one important point

27:32

remember the QT interval from the

27:35

beginning of the Q wave to the end of

27:36

the T-wave and we'll come to that when

27:38

we discuss

27:40

during this interval the tricuspid valve

27:42

is closed so if the atrial activity

27:45

occurs it will generate an e so every

27:48

nar re-entry ticardia and every re-entry

27:52

ticardia in other ways

27:54

Short RP ticardia. There is atrial

27:56

activity occurring during the closure of

27:58

the tricuspid valve. Closure of the

28:01

tricuspid valve during the canon the QT

28:05

interval. This is called the canon zone.

28:07

So they produces irregular canon waves

28:10

but at a pos. So this is important

28:14

points my messages. We go to the second

28:17

question.

28:18

Splitting of the similunar valves is

28:21

associated with the following

28:23

statements. It occurs normally in

28:25

expiration. In left bundle branch block

28:28

it occurs during inspiration. In right

28:31

bundle branch block it occurs during

28:33

inspiration and expiration and is

28:36

greatest or loudest in severe stenosis.

28:39

The appropriate answer I'm looking for

28:41

is number C. Right bundle branch block.

28:45

The splitting of the second sound occurs

28:47

in inspiration and expiration. And that

28:50

leads me to discussion of the heart

28:52

sounds.

28:54

The heart sounds, the first heart sound

28:56

is composed of a mital component and

28:59

recuspic component. The second heart

29:01

sound is composed of aortic component

29:03

and pulmonary component. We know that

29:05

right sided val

29:07

earlier and they close last. And what

29:10

happens in inspiration? Increased Venus

29:13

return increased the preload the mital

29:15

and the tricuspidal valve gets widely

29:17

separated but this degree of separation

29:20

is just 20 to 25 millisecond for the

29:23

average ear and average temporal lo you

29:26

cannot distinguish this splitting some

29:29

people try to convince us they hear the

29:31

split second first sound that's okay but

29:33

that's not the common thing but this is

29:35

in contra distinction to to the second

29:38

heart sound the second heart sound

29:40

occurs a2 occurs before P2. And why is

29:44

that? Remember when we talked about the

29:47

second point on the WERs diagram, we

29:50

talked about when we started the

29:52

isopolomic relaxation period on the left

29:55

side of the heart, the aortic grad

29:57

closes and that produces whatever it

30:00

produces to to result in A2.

30:03

But what happens on the right side of

30:05

the heart is completely different. At

30:08

the beginning of the isovolomic

30:10

relaxation period,

30:13

the pulmonary valve doesn't close. The

30:16

blood flow from the right ventricle

30:18

continues to flow into the pulmonary

30:20

circulation despite the start of the

30:22

isoblomic relaxation. And why is that?

30:26

That this is because the compliance of

30:28

the lung prevent the the the

30:31

closure of the pulmonary ve the

30:33

compliance is in is why is increased. So

30:36

the blood continues to flow and as a

30:39

result of that P2 occurs a certain

30:41

interval after E2. This per period, this

30:46

time period between the closure of the

30:49

pulmonary valve and the closure of the

30:53

aortic valve is called the hang out

30:55

interval and the reason is the

30:57

continuing flow of the pulmonary blood

30:59

of the pulmonary blood despite the fall

31:03

of the right ventricular diastolic

31:05

pressure below the pulmonary pressure.

31:07

Now if you take a deep breath the penis

31:09

return will increase the blood flow

31:11

across the pulmonary circulation will

31:12

increase and A2 and B2 will widen. So

31:16

the hang out interval will increase it

31:19

can reach to 60 milliseconds that's all

31:22

and vice versa during expiration.

31:26

So paradoxical splitting is a situation

31:29

is always pathological and is a

31:32

situation in which P2 occurs first. A2

31:36

is delayed. Why it's delayed? Because

31:38

there is delayed activation of the left

31:40

ventricle like in patients with left

31:43

branch block like in right ventricular

31:45

pacing like for example if you have um

31:51

uh an aortic stenosis. So as a result of

31:54

that type BW WBW also there is a delayed

31:57

activation of the lift vent or you have

32:00

a prolonged ejection actually prolonged

32:03

pre-jection period if you have an aortic

32:06

stenosis the ejection period will be

32:08

elevated if you have patient patients

32:10

with heart failure the pre-jection

32:12

period will be increased the ejection

32:14

period will be shortened but the time

32:16

from the start of contraction and the

32:20

closure of the second will be prolonged

32:23

So always when you get paradoxical

32:25

splitting you are going to have an

32:27

unfysiological situation persistent

32:30

splitting occurs in right border branch

32:32

block and the pulmonary hypertension and

32:34

we will detail that very soon and you

32:36

get fixed splitting in atrial sector

32:38

defect because it's well known that

32:40

increased Venus return will be balanced

32:42

by reciprocal diminion of the sh across

32:45

the atrial circle.

32:49

Now let us detail about what happens in

32:53

the stoolic periods. In the astrology we

32:56

have the third heart sound and the

32:58

fourth heart sound. And since the the

33:01

both of them both of them are diastolic

33:03

events they do not correlate with the

33:05

ejection fraction. The ejection fraction

33:07

is a systolic event. Hearing a third

33:10

heart sound or hearing a fourth heart

33:12

sound does not let you guess what's the

33:15

ejection fraction. It gives information

33:17

which we are going to detail now but it

33:19

doesn't tell you about the uh the

33:23

ejection fraction. Now let's see what's

33:26

happening during third sound. Tell our

33:28

son if the patient is below the age of

33:31

30 and he does not he does not he does

33:35

not have any manifestations of cardiac

33:38

disease no cardiac enlargement no

33:40

ejection click no diastolic mm no

33:42

paradoxical splitting then it's

33:44

physological with the age of 30 and

33:47

there is no company that it keeps with

33:49

it no evidence of other disease it's

33:52

it's physiological now the genesis of

33:55

the of the third found under

33:57

physiological circumstances is different

34:00

from LCGenesis under pathological

34:02

circumstances. Here the active

34:04

relaxation of the left ventricle brings

34:06

the left ventricular pressure curve to

34:08

sub zero and then there is an area

34:11

between the left atrial pressure and the

34:13

left ventricular pressure. The left

34:15

ventricle being actively relaxing so to

34:18

speak sucks the blood from the left

34:20

atrium and produces the resonation into

34:22

the left ventricular cavity responsible

34:24

for the generation of the third heart

34:26

cell. But if we have heart failure with

34:29

systolic dysfunction or preserve it

34:31

systolic dysfunction or preserve its

34:33

systolic function then we will find that

34:35

there is elevation of the left

34:37

ventricular thetoric pressure. The left

34:40

atrial pressure is even higher and the

34:42

left atrial pressure has to push the

34:45

blood rather than to suck the blood in

34:47

this under this circumstance. But both

34:50

of them both of them are related to this

34:53

period of the cardiac cycle. Both of

34:56

them are manifestations of filling of

35:01

the left ventil whether it's being

35:03

sucked or whether it is pushed. Actually

35:06

what differentiates between whether it's

35:08

a physiological third sound or

35:10

pathological third sound is two things

35:14

age below 30 age above 40 but more

35:18

importantly the company it keeps here we

35:21

get manifestations of heart disease

35:23

cardiac enlargement symptomatology

35:26

patient is having either stoic murmur is

35:29

having pathological clicks and so forth.

35:32

The fourth heart sound corresponds to

35:34

the late diastolic event. This is the

35:37

occurrence of atrial activity pushing

35:40

the blood into the vent. Remember it's a

35:43

ventricular phenomena. It's not an

35:45

atrial phenomena. It's related to the

35:47

atrial contraction but is not caused by

35:50

the atrial contraction. If you have a

35:52

stiff ventricle like in patients with

35:54

hypertension like in patients with left

35:56

ventricular hypertrophy then you get

35:59

stiff ventricle atrial pressure rises

36:02

pushes the blood but resolution occurs

36:04

in the left ventricle and as a result of

36:06

that you get an S4. So S4

36:10

previously we saw that S4 in old age is

36:12

a physiological phenomena. This is

36:15

extremely doubted. You can safely say

36:17

that S4 is always pathological. S3 can

36:20

be physiological and can be pathologic.

36:24

Remember S4 disappears in atrial

36:26

fibrillation. But there are other

36:28

situation in which you can never get an

36:30

S4. Micro stenosis is one of them. You

36:33

cannot get transmission of the left

36:35

atrial high pressure to the left

36:37

ventricle being protected by the

36:38

stenotic mal. Another situation is

36:41

constructive paraglides. Impossible.

36:44

Why? Because most of the blood filling

36:47

the left ventricle occurs in early area

36:49

in the rapid filling period and there is

36:51

small remaining amount of blood in late

36:54

diast. So there is no need for the atria

36:56

to contract strongly. So atrial

36:58

fibrillation consecutive pericarditis

37:00

per menosis are these are the important

37:04

three conditions in which you don't get

37:07

an S4 impossible.

37:09

Now is S3 the only early diastolic

37:13

sound? No. You can get an opening snap.

37:15

You can get a tumor plot. You can get a

37:17

pericardial knock. Previously, we can

37:20

get the the opening sound of uh the old

37:24

kinds of prosthetic valves. All of these

37:27

are early diastolic feelings. What about

37:30

pulmonary P2? P2 gets accentuated in

37:34

pulmonary hypertension. But remember

37:36

from the start that the degree of

37:39

loudness of the pulmonary component of

37:42

the second heart sound doesn't have

37:44

anything to do with the degree of

37:46

elevation of the pulmonary arterial.

37:49

Number two, what about the splitting of

37:52

the second heart sound? The important

37:55

feature of pulma hypertension is

37:56

accentuated P2. If it is held on the

37:59

apex, it's accentuated because normally

38:02

it is not heard except on the pulmonary

38:05

area. If it can travel to the apex, it's

38:07

accentuated. Whether the second art

38:10

sound is closely split, is single, is

38:13

widely split or normally split. The four

38:16

conditions occur in perman hypertension.

38:18

Let me give you examples. In the garden

38:21

variety, common type of perman

38:23

hypertension particularly the early

38:25

stages, it's closely split. the hang out

38:28

interval gets

38:30

shrunk because of the increased

38:34

stiffness of the lung and the pulmonary

38:35

circulation. But in another condition

38:38

like for example as a minger VCD it's

38:41

single

38:43

if you get pulary hypertension with

38:45

pulmonary artery dilation

38:48

then under this circumstances you get

38:49

normally splitting the hang out interval

38:52

gets normal because of the increased

38:55

compliance of the pulmonary circulation

38:57

and you sometimes you get wide splitting

39:00

pulmonary embolism is an is an example

39:03

in pulmonary embolism the right vertical

39:05

fields pre-jection period of the right

39:08

until it gets prolonged. P2 gets

39:10

delayed, pulary hypertension is there,

39:12

but the second out sound is why it is

39:14

split. So the degree of splitting is not

39:16

that important in diagnosing pulary

39:18

hypertension. It is the accentuation of

39:21

P2. If it's heard over the apex, then

39:24

you know it's loud. If it's loud, you

39:26

cannot predicted the degree of elevation

39:28

of the pulmonary artery pressure under

39:31

this circumstance.

39:34

Now let's question. A 60-year-old female

39:37

presents with vague non-exertional chest

39:39

pain. She has a history of long murmur

39:42

but has been asymptomatic until

39:43

recently. S1 and S2 is normal

39:46

physiological splitting of the second

39:48

sound. There is a midstoric click heard

39:51

over the apex and preceded and preceded

39:54

onetoric me and the important thing is

39:57

is coming here. Now upon rising promptly

39:59

from the sitting to the standing

40:01

position the systolic leaks moves early

40:03

in history and the memor gets longer

40:07

and longer and more longer. So everyone

40:11

knows that this is mital valve prolapse.

40:13

The clinical findings are most

40:14

consistent with hypertrophic cardopathy

40:16

cannot be because there is a click

40:18

innocent cannot be because there is a

40:20

click mitral valve prolapse with mild

40:22

malage that's the appropriate answer by

40:25

cusp aortic valve and severe aortic

40:27

stenosis this is an injection click and

40:29

not an injection click so that

40:31

introduces us to the historic mas now

40:34

the most important is to find out

40:36

whether this historic murmur is innocent

40:39

or functional m is a pathological memor

40:42

The American Society of Echo

40:44

cardiography in insists that you

40:47

investigate by echo systolic mm that are

40:50

pathological. And the class three

40:52

recommendation is to put the patient for

40:55

echo study when he has an innocent

40:57

murmur. The innocent murmur is usually a

40:59

short murmur. It's usually grade one to

41:02

two in intensity. It's held at right

41:04

sternal border. It's systolic ejection.

41:07

If you decrease the payload, for

41:09

example, by letting the patient stand

41:10

up, then usually it decreases in

41:13

intensity, it has no other pathological

41:16

features associated with it. No

41:17

diastolic murmurss, no abnormal sounds,

41:21

no gallops, no clicks and so forth. No

41:23

cardiac enlargement. Now

41:27

there are very important functional

41:29

mess. Aortic sclerosis for example in

41:32

old age this is a functional systolic m.

41:34

But remember

41:36

10 to 25% of patients with aortic

41:39

stenosis will end up having aortic

41:42

stenosis and many of them will undergo

41:44

surgery or that's one thing this is in

41:48

contra distinction to the situation with

41:50

bicuspid aortic valve bypid valve the

41:53

murmur is not a an innocent m but

41:56

remember as a corerary that this

41:59

bicuspid aortic valve if you have a

42:00

bicuspid or valve and you reach the age

42:03

of 60 or

42:04

then sure you will be having either a

42:07

severe aortic stenosis or severe aortic

42:09

regation that needs intervention. So the

42:12

situation is different between our

42:14

screws and our andobic our now we have

42:18

other conditions in which there is a

42:20

function historic murmur in infants on

42:23

the other hand and in children you have

42:25

a steel's m still murmur is a vibratory

42:28

murmur sometimes it has a musical

42:31

character heard along the right sternal

42:33

border we don't know whe what is the

42:36

origin of it the proposal is that it's a

42:38

vibration of the event or a false tendon

42:42

in the left ventricle.

42:45

Sometimes we hear a cervical venus hum

42:49

in my professional life I didn't hear a

42:52

cervical venus sound I read about it now

42:54

the cervical venus hum is a continuous

42:57

me with a more prominent story component

43:01

and is heard in the supraclavicular

43:03

fossa and to the right of the sternum

43:05

and gets louder when the patient moves

43:07

his neck to the left side of the heart

43:09

it's due to acceleration of the blood in

43:11

the venus system but it's extremely

43:14

so That's enough about systo functional

43:16

systolic memor. Now we go into the

43:18

clicks. The we have two types of clicks.

43:21

Ejection clicks and non- ejection click.

43:23

You should be able and find out the

43:25

difference by palpating the corroted

43:27

pulse. If it occurs at the rise of the

43:29

corroted pulse in the anacrotic

43:32

anacrotic limb then you ought to think

43:34

of bicuspid aotic valve or bicuspid

43:36

pulmonary valve and I detailed the

43:38

importance of bicuspid aortic pad

43:40

autotoal dominant disease with low

43:42

penetrance 9% inherence our non-

43:46

injection click the common by far my

43:49

drug prolapse differential diagnosis

43:51

will be ventricular analysis at

43:53

receeptal analysis cardiac tumors pulary

43:56

hypertension and systemic hypertension

43:58

and important to notice all rights sided

44:02

phenomena increase with inspiration

44:04

except one thing the systolic ejection

44:07

click of permanent origin. Why is that?

44:11

Because if you take a deep breath then

44:13

the atrial complexion at that time with

44:15

the deep breath will increase the

44:17

ventricular pressure and opens the

44:20

pulmonary valve partially. Now systolic

44:22

ejection starts now. So it opens it from

44:25

the partial open position to the

44:28

complete open position. So that doesn't

44:30

produce sound or produces a faint sound.

44:33

So the only right-sided phenomena which

44:35

decreases with inspiration or the with

44:39

increase the preload is the pulmonary

44:42

ejection click otherwise everything on

44:44

the right side increases with

44:45

inspiration particularly tricaspid

44:48

what's called carval side.

44:52

Now we go into the systolic murmurss.

44:57

Most prominent among these is mitral

44:59

regurgitation which comes in two flavors

45:02

acute and the chronic and they are

45:05

completely different. Now the acute

45:07

mitral reg you get a very short systolic

45:10

m as a matter of fact most of the time

45:12

we don't hear it. Why is that? Because

45:15

the left ventricular

45:18

the stoic pressure will be high and

45:21

during ejection it will eject the blood

45:24

into the left atrium which is not

45:26

dilated and as a result of that the

45:28

pressure in the left atrium is high. So

45:30

the gradient builds up into the left

45:33

atrium very quickly and the merma is

45:35

short and determinates here in midtory

45:38

or but more importantly these patients

45:40

are usually in pulmonary edema. So you

45:43

have a lot of crackers, a lot of

45:45

bubbles,

45:46

wheezes over the chest which should

45:48

prevent you from hearing this up. Now

45:50

how how can we detected this condition?

45:53

If you find a patient with myocardial

45:55

infarture or an acute event including

45:57

the trauma and the calf ventricle

45:59

despite that is hypercinetic.

46:02

Be careful to look for a short systolic

46:04

murmur and investigate for that because

46:07

that might be an acute m regurgitation.

46:10

In acute micro regurgitation like in any

46:12

micro regurgitation we get third heart

46:14

sound but a specific entity here is a

46:17

fourth heart sound. Previously we

46:19

explained this for heart sound that the

46:21

left atrium gets angry indignant and its

46:25

contraction produce this sound. But

46:27

probably this sound is secondary to

46:29

eskeia which is underlying it of the

46:32

acute malage. Now the situation is

46:34

different from chronic malage where you

46:36

get a panctoric me. Everyone knows about

46:39

that. But why I want to make a point

46:41

here you know everyone knows that this

46:44

historic advanced historic memor starts

46:46

early here in history. So there is no

46:48

isolomic contraction period but it's not

46:51

very well known to many of you that it

46:54

overlaps the aortic component. Another

46:57

feature of the pancistolic memor is that

47:00

if this is A2 it ends after A2. Why is

47:03

that? Because at the time of closure of

47:06

the aortic valve there is still a

47:08

gradient between the left ventricle and

47:10

left atrium and the blood continues to

47:12

flow. So as a result of that it starts

47:15

very early and it terminates after a2.

47:18

So these are the same quanton features

47:21

of a panctoic me in compar distinction

47:23

to the short systolic m of acute mage.

47:27

And here is the the key differences

47:29

between acute and and chronic microage.

47:33

These patients are sitting upright

47:35

because of the pulmonary edema. They

47:37

have rolls all over. They have a short

47:39

or a subtle murmur in contra distinction

47:41

which happens in chronic mary. You get

47:44

left ventricular enlargement. You get

47:46

pulmonary hypertension or very minimal

47:49

pulmonary findings due to congest

47:51

chronic congestion. Not the pulmonary

47:53

edema findings here. and you get a third

47:56

heart sound that might be palp remember

47:59

if you palpate a gallop it's

48:01

pathological situation now it's very

48:04

well known that you can identify which

48:06

leaflet is pathological if the if the

48:08

mermma is radiating to the sternal

48:10

border it's the the the

48:13

posterior leaflet if it's radiating to

48:15

the axilla and to the back the anterior

48:18

leaflet other causes of holy systolic

48:20

murmur including the tricuspation and

48:22

vvelic defect remember that mitro reg

48:28

the systolic mammar gets accentuated by

48:31

increasing the afterload you elevate the

48:34

blood pressure by kinking femoral artery

48:36

or by squeezing your fists hand grip

48:40

they increase but truspid

48:43

increases by increasing the preload you

48:45

take a deep breath and it increases

48:49

now this tells us the physical findings

48:52

that are diagnostic of mital verd prolap

48:54

It's a confusing situation but if you

48:56

find this physical signs which might not

48:58

be present in every case but they are

49:00

present it clenches the diagnosis

49:02

irrespective of what. Now if you squat

49:06

actually what you do is increasing the

49:08

preload and the after load. You kink the

49:10

femoral artery and that increases the

49:12

afterload or the pressure and you

49:14

squeeze this planking circulation. In

49:16

this conditions you increase the penis

49:18

return or the preload. As a result of

49:21

these two events, you increase the left

49:22

ventricular size. The prolapse will

49:24

occur later. The liquid moves later and

49:27

then the mmer will become shorter and

49:30

usually fainter.

49:32

If you stand then the opposite occur.

49:35

The preload will decrease the after load

49:37

will decrease. Left ventricular size

49:39

will decrease the click comes earlier

49:41

the murmur will become longer and will

49:43

become louder. And that's important. Now

49:46

the same changes occurs in hypertrophic

49:49

but there is no click in hypertrophic.

49:52

So finding the click sculptating the

49:54

click making sure it's existing can

49:57

differentiate between these two

49:58

situations which can be confused with

50:00

each other. This leads us the commonest

50:03

murmur abroad is aortic stenosis murmur

50:06

historic ejection murmur classic

50:09

teaching is that if you have the peak

50:11

delayed then you have a severe aortic

50:15

stenosis but at that time we didn't know

50:18

much about stage D2 and D3 aortic

50:22

stenosis aortic stenosis with low flow

50:25

low gradient types of aortic stenosis

50:28

under this circumstances you might get

50:30

severe aortic stenosis is a faint murmur

50:33

with an early peak. So this murmur is

50:36

classic for the unusual types of aortic

50:39

stenosis but not classic for the unusual

50:42

forms what we call stage D2 and D3 or

50:46

the low flow low gradient aortic

50:48

stenosis. But a constant feature of

50:51

aortic stenosis is the weak faint or

50:54

absent A2. You get the val sclerotic.

50:56

You get the val fibrotic get the

50:58

valified A2 disappears. But generally

51:02

classically you get here an delay

51:04

ejection m delay and ejection systolic

51:07

mm great peak weak A2 means the presence

51:12

of severe aortic stenos. But what about

51:14

S4? S4 cannot be used to identify the

51:19

severity of the aortic stenos. These

51:22

patients very commonly have eskeemic

51:24

heart disease have associated chronic

51:26

heart disease. S4 might be a reflection

51:29

of that rather than the severity of the

51:32

aortic stenosis. Now here she shows us a

51:35

conditions of severe aortic stenosis

51:37

where the murmur goes all the way and

51:40

even it drowns the P2. A2 is delayed. So

51:45

if P2 occurs earlier and there's a

51:48

paradoxical splitting. How can we know

51:49

that? Take a deep breath. P2 moves

51:52

towards A2 and the ner splitting gets

51:54

narrow. Usually we don't give attention

51:57

to paradoxical splitting but sometimes

51:59

they are very helpful signs in clenching

52:01

the diagnosis. You might say that let's

52:04

do an echo for the patient but you can

52:06

do an echo and you get confusion. You

52:09

can do an echo and your clinical science

52:11

say that this is severe.

52:14

The echo says no. Now under these

52:16

circumstances you can go back and do an

52:20

echo with another windows from the right

52:23

sup right parna from the supraclav by

52:26

the ped

52:28

probe from the subternal angle you might

52:31

like to do a transopial you might do a

52:33

palmmetry by 3D and do different things

52:38

and can you can check your physical

52:40

signs as well so on either way you don't

52:43

use them physical signs against

52:45

investigation as competitors but as

52:47

complimentary and as a checker of each

52:50

one against the other.

52:53

Now in hypertrophic cardiammyopathy

52:56

which is a very common condition the

52:59

apex beat is either pifid or triple and

53:02

the triple it's called it the triple

53:04

ripple the triple pulsations is due

53:07

prehistoric gallop and then two

53:09

pulsations one before the injection

53:12

before the obstruction in the outflow

53:14

tract and the second after the

53:16

obstruction of the outflow tract. Now

53:18

this is important. Why? Because every

53:21

now and then we examine athletes and

53:24

there's a confusion between the physical

53:26

findings, electroc cardioraphic

53:27

findings, investigation findings between

53:29

hypertrophic cardmopathy and the athlete

53:32

arm. Simple physical examination if you

53:34

find triple ripple it clenches the

53:36

diagnosis cannot be present in the

53:38

athlete.

53:39

An important thing

53:42

in in hypertropical neopathy is a

53:44

presence of a loud murmur. Usually the

53:46

murmur is loud and anything which

53:49

shrinks the left ventricular volume

53:50

accentuates the murmur. This murmur is

53:53

commonly heard in the sternum but the

53:55

associated mal regurg because of

53:57

movement of the anterior leaflet of the

53:59

mital valve generates another murmur

54:01

goes to the axilla and even to the back.

54:04

But the important thing here is the

54:06

effect of the strain phase of our salva

54:08

maneuver. By the way, Balva was an ENG

54:11

specialist has nothing to do with

54:13

cardology and he was you used the

54:16

maneuver of straining it to discharge

54:19

bus from the middle ear but somehow how

54:23

it found its way to cardiology and is

54:26

being used frequently for

54:28

differentiating the types of Mer. Now

54:30

during the strain phase venus return is

54:32

hampered preload is diminished. This

54:35

diminishes the murmur of valvular

54:38

stenosis because the flow will diminish

54:40

but will shrink the ventricular size

54:42

increase obstruction and decreases the

54:44

murmur. A my nitrite is no longer used

54:47

or PVC does not differentiate. So the

54:49

differentiation between a stenosis and

54:51

hypotropical neuropathy is essentially

54:54

by realva maneuver during the strain not

54:58

the release phase. And this brings us to

55:01

dynamication. We have a variety of

55:03

things am I tried we don't use them hand

55:06

grip hand grip we usually do it by

55:09

making a hand grip of both arms and try

55:13

not to use the the the diaphragm of the

55:15

stethoscope because it might make a

55:17

friction against the contracting

55:19

pectoralis major use the belt and make

55:22

sure that you are not hearing the

55:23

contraction of the pectoralis major if

55:26

you do a handicap it increases the blood

55:28

pressure increases the afterload as a

55:30

result of that mig increases aortic gage

55:34

diminishes and under these circumstances

55:36

the left ventricular cavity increases.

55:38

So the obstruction will diminish and

55:41

hypertrophic cardopathy will decrease

55:43

and as we said vulva will diminish the

55:46

preload during the strain phase and

55:48

differentiates between our stenosis and

55:50

hypertrophic cardia but the square to 10

55:54

is is the most important findings to

55:56

differentiate these three uh

55:59

pathological conditions. is not sitting

56:02

to stem. It's squat to stem. You cannot

56:05

get much differentiation between sitting

56:07

to stem. Now if you squat, you kink the

56:10

femoral artery and so you increase the

56:12

afterload. You compress the splanking

56:14

circulation you increase the preload and

56:17

these two conditions will increase the

56:19

mm of my will decrease the m of stenos

56:23

and hypertrophical.

56:25

So when hypertrophic nemopathy if you

56:28

squat you increase the left ventricular

56:29

size the dimensional obstruction you

56:31

diminish the murmur now you stand up the

56:34

reverse occurs the murmur increases

56:36

while the other two there is no change

56:39

postVC is important if you find a long

56:42

cycle whether it's an atrial

56:44

fibrillation long cycle or the whether

56:46

it's a PVC after it there is a post PVC

56:50

compensatory period in which you during

56:53

this condition you get increase in the

56:54

afterlow Because of the reparation of

56:56

calcium during the PVC you increase

56:59

contractility and this conditions this

57:02

PVC with a long cycle operate you will

57:05

find under this circumstances in this

57:07

contractility. So the murmur of

57:09

hypertrophic cardopathy increases

57:11

because of increased contractivity but

57:13

it doesn't affect the murmur of mital

57:15

gage always the gradient is very high

57:18

between the left ventricle and the left

57:20

atrium. So this minimal changes doesn't

57:22

affect it. So remember post pregnancy or

57:25

long cycle lateral fibrillation

57:27

differentiates between the murmur of

57:29

mital reg and hypertrophic myopathy but

57:32

unfortunately you might get the two

57:34

situations.

57:36

Now this leads us to diastolic mmmers

57:38

aortic regurgitation remember in aortic

57:41

regurgitation it's not early diastolic

57:43

murmur only it's an early diastolic

57:46

murmur and historic murmur. So this is

57:48

the two and through murmur of aortic

57:50

regation and again we get aortic

57:54

regation in two levels chronic aortic

57:56

regic murmur the length of the murmur

58:00

rather than the intensity of the mar is

58:02

what determines the severity of aortic

58:05

reg but the most important findings in

58:08

aortic in pre-awortical gage is a white

58:10

passion you can never get a severe

58:13

aortical gauge uncomplicated

58:16

not complicated but failure not

58:18

complicated by aortic stenosis, not

58:20

complicated by mitroenosis. You cannot

58:22

get a free uncomplicated oric gage

58:25

without a white pulse pressure. Remember

58:27

this.

58:29

Now the the regurgitation of the blood

58:32

from the aorta the left ventricle will

58:35

push the anterior lift of the mital

58:36

valve to the semi-closed position

58:38

creating something like mital stenosis

58:40

and therefore you get a midtoic murmur

58:43

known as the oip.

58:45

In patients with acute aortic reg for

58:48

example the if you get an aortic

58:50

dissection under this circumstances the

58:53

blood flowing from the aorta to the left

58:55

ventil marketly elevate the left

58:57

ventricular endos pressure and stops the

59:00

murmur right here. So the mer is shown

59:03

and you may not be able to detect it at

59:05

all.

59:07

Now mitro stenosis very well known to

59:09

everyone but I wanted to make certain

59:11

points here. In early mital stenosis

59:14

there are two members. It's not one

59:16

single murmur. Now these two mmas is an

59:18

early diastolic murmur here following

59:20

the opening snaps. Not actually early in

59:23

terms of being after E2, but there is a

59:26

space after the opening step. You get an

59:28

early due to the flow of the blood from

59:30

the left atrium to the left ventricle

59:32

during the rapid filling period and then

59:35

you get an area of silence and then as a

59:37

result of atrial contraction you get

59:39

another M. Remember that this piece of

59:42

the murmur is actually not a diastolic

59:45

phenomena. This is the first heart

59:47

sound. This is the beginning of clinical

59:49

history. But it's not the beginning of

59:52

physiological history. Why is that?

59:54

Because the left ventricle contracts

59:56

before the first heart sound has to move

59:58

the blood which gets deceleration behind

1:00:00

it. So actually the left ventricle

1:00:03

starts contracting here. So this part of

1:00:06

the murmur is in actual physiological

1:00:09

system and that's the reason if you have

1:00:12

atrial fibrillation no atrial kick the

1:00:15

prehistoric accentuation might and might

1:00:18

not disappear.

1:00:20

Now if m stenosis becomes severe then

1:00:23

the gradient will not be not early and

1:00:25

not late only that but will be all

1:00:28

through. So you get the long rumbling

1:00:30

the stoic murmur which ends with an

1:00:32

accent sound. Now everyone is acquainted

1:00:36

between the significance between A2 and

1:00:39

the opening snap. The tighter the

1:00:41

stenosis, the closer interval. But mind

1:00:44

that there are two exceptions of this.

1:00:47

Hypertension

1:00:48

as well as atrial fibrillation. In

1:00:50

hypertension the isovalometric

1:00:53

relaxation period is prolonged because

1:00:55

you have to drop down from the high

1:00:56

aortic pressure down to below the left

1:00:59

atrial pressure in order to for the

1:01:02

mital valve to open. So you get widening

1:01:04

of this interval even if mistenosis is

1:01:07

is tight and in long in atrial

1:01:10

fibrillation long cycle is inversely

1:01:12

proportional to the left atrial

1:01:14

pressure. So sometimes opening the

1:01:18

aortic valve the mital valve prematurely

1:01:21

despite the micro stenosis is not that

1:01:24

severe. So taking these precautions in

1:01:26

consideration is important. An important

1:01:29

thing which not known to everybody if

1:01:31

you get a loud first sound. If you get a

1:01:33

crisp opening snap you have mital valve

1:01:36

you expect that the mital valve score

1:01:39

will be less than eight and the patient

1:01:41

is fit for mital val.

1:01:44

Now

1:01:46

uh going to the stoic murmurs other

1:01:48

diastolic mmmers pulmonary regurgitation

1:01:50

is very important nowadays. Why is it?

1:01:54

We know that in severe pulmonary

1:01:56

hypertension, pulmonary regurgitation

1:01:58

can occur under the circumstances

1:02:01

P2. But sometimes you get a pulmonary

1:02:04

gurge and the pulmonary second sound is

1:02:06

not that loud. For example, in patients

1:02:09

with carcinoid syndrome, pulmonary valve

1:02:12

is is fixed in the semi-open position

1:02:15

cannot close, cannot produce a loud P2.

1:02:18

But more importantly this situation in

1:02:21

focusology required a surgeon opens the

1:02:24

outflow tract of the right vent. He

1:02:26

splits open the pulmonary valve the

1:02:28

pulmonary artery out of the pulmonary

1:02:30

artery and the outflow tractor of the

1:02:32

right ventricle. Under this

1:02:34

circumstances he creates pulmonary

1:02:36

leage. Now this pulmonary gauge is awful

1:02:40

and is hardly to detect. Why hardly to

1:02:43

detect? We know that the pulmonary

1:02:46

artery pressure is low in ferocythology

1:02:48

and if you open the pulmonary the

1:02:52

outflow plaque of the right ventricle

1:02:53

the right ventricle pressure is going to

1:02:55

drop the gradient will be minimum. So

1:02:58

despite free flowing perman the murmur

1:03:03

will be very soft because the gradient

1:03:05

is not that great but moreover the flow

1:03:09

will be laminar because the the

1:03:12

permonary cusps will be will be gone

1:03:16

almost disappeared completely after

1:03:18

surgery. So as a result of that if you

1:03:20

put the echo and you are not very

1:03:22

attentive you will not find elasin and

1:03:24

as a result of that you can miss you can

1:03:28

miss the situation all together. How can

1:03:30

you find it? You find that the right

1:03:32

ventricle after operation is getting

1:03:36

dilated white complex reaching point 18

1:03:41

ventricular ticardial occur. A role of

1:03:44

thumb in arismia complicating the

1:03:46

congenital heart disease. If you get

1:03:48

arythmia look for underlying hemodynamic

1:03:51

disturbance. If you corrected the

1:03:54

hemodynamic disturbance most likely the

1:03:56

arythmia is going to disappear. If the

1:03:58

ventricular arisma doesn't disappear you

1:04:00

think of an ICD. Don't think in ICD at

1:04:03

the beginning. Corrected hemodynamic

1:04:05

abnormality and that's a rule of thumb

1:04:07

which applies to the majority of

1:04:09

situations of congenital heart disease.

1:04:11

This is this situation is no exception.

1:04:14

So here you get pocosology. You get a

1:04:16

low pitched early diastolic murmur. Your

1:04:18

pulmonary regurgitation. Make sure that

1:04:21

your right ventricle is not dilated.

1:04:23

Don't miss this situation because it's

1:04:25

an ominous situation. Now continuous

1:04:28

murmur. The definition of a continuous

1:04:30

murmur is a murmur which starts in

1:04:32

incestually anywhere in cy not

1:04:35

necessarily at the beginning of system

1:04:37

and continues across the second cell to

1:04:40

diasty anywhere in the not necessarily

1:04:43

at the end of the prominent among the

1:04:46

causes is rupture silence of UB cervical

1:04:50

venus which we talked about just a while

1:04:53

ago remember coactation coactation the

1:04:56

collateral can create a lot of problems

1:04:58

can create a continuous murmur and can

1:05:01

create a falsely low gradient across the

1:05:04

coation. Remember the significant

1:05:07

gradient across the cartition is just 20

1:05:09

mm of mercury. Astonishingly low. Don't

1:05:14

forget the examination of the vascular

1:05:16

part of the cardiovascular examination.

1:05:19

And in this regard, I want to point out

1:05:22

the following. Number one, the majority

1:05:24

of peripheral art disease are

1:05:26

asytomatic. At least half of the

1:05:28

patients with peripheral artery disease

1:05:30

they don't have any symptoms and this

1:05:32

means that you have be on the lookout

1:05:34

for this and that's why guidelines is

1:05:36

recommending doing the ankle break index

1:05:39

in patients above the age of 65 or 70 as

1:05:42

a routine too much but that's a

1:05:44

guideline

1:05:46

or patients above the age of 50 or 55 if

1:05:49

they have diabetes or they are smokers

1:05:51

but remember peripheral artery disease

1:05:53

commonly asytomatic and if even if they

1:05:56

have symptoms. Intermittent clication.

1:05:59

Intermittent chordication is usually a

1:06:02

typical is not the pain which occurs on

1:06:04

exercise stops at least within 10

1:06:07

minutes and doesn't occur at rest. These

1:06:09

are the three classic criteria of

1:06:11

intermittent collication. They are not

1:06:13

present in the majority of cases. If the

1:06:15

asymptomatic is 50, a typical

1:06:18

collication is 35, typical collication

1:06:22

is 15%.

1:06:24

Clical limb eskeemia is a term which

1:06:26

conotes presence of rest pain

1:06:28

incapacitating

1:06:30

or rest pain or the presence of t loss

1:06:33

in the form of ulcer or in the form of

1:06:35

gender.

1:06:37

One simple test is the burgers test.

1:06:39

Revate the leg of the patient. And if

1:06:42

you reate the leg of the patient to a

1:06:44

degree like to 45 degrees, you get color

1:06:47

because the venus blood is went away and

1:06:50

the partial blood cannot replace it. And

1:06:52

if you drop the leg at the bedside you

1:06:55

get rer. This roer is delayed because

1:06:58

filling filling is filling from

1:07:00

collaterals. And the reason why there is

1:07:02

ruper is the capillary dilation the

1:07:04

eskeemia is producing accumulation of

1:07:06

metabolites and this accumulation of

1:07:08

metabolites will result in plaso

1:07:11

dilotation and ruper in this this is

1:07:13

burgers test now this is very important

1:07:16

the ankle brachial index it's not only

1:07:19

important because it detects peripheral

1:07:21

vascular disease it's important because

1:07:24

it detects peripheral artery disease

1:07:25

particularly we know that peripheral art

1:07:28

peripheral arterial disease is commonly

1:07:30

signed

1:07:31

But its importance is a risk factor for

1:07:33

coronary artery disease and for strokes.

1:07:35

So it's an important. So everyone should

1:07:37

be acquainted how it's being done. Not

1:07:39

necess not necessarily to be how to do

1:07:42

the technique exactly. But remember the

1:07:45

technique should be done preferably with

1:07:48

the Doppler ultrasound. And here it's

1:07:51

the monometer no longer is used to do

1:07:53

that. What we do here this ratio here

1:07:56

it's it's a systolic ankle pressure over

1:07:59

the systolic arm pressure. What we do is

1:08:02

that we measure the uh arm pressure by

1:08:04

the Doppler in the brachial artery and

1:08:07

we choose the higher of the two

1:08:09

pressures right and left leg limb and we

1:08:12

measure the two ankle pressures right

1:08:14

and left and in each ankle dorsal pedis

1:08:17

and posterior tibial and we choose the

1:08:20

posterior tibial or the dorsal pedis

1:08:22

whichever is higher. So it's the higher

1:08:24

of the two angle pressures over the

1:08:27

higher of the two arm pressures for the

1:08:30

right side and left side. Now this is

1:08:33

important

1:08:35

and this is an example although there is

1:08:37

also a mistake here. This is the right

1:08:40

side and left side 160 150. Here is the

1:08:45

posterior tier is 120. The cell speed

1:08:47

this is 180. So we choose here the

1:08:50

higher of the two 120 divide it by the

1:08:54

higher of these two. So 120 over 160.

1:08:58

This figure here is 80. So we choose the

1:09:01

the higher here which is 80 over 160 not

1:09:05

150 because we we we use the higher of

1:09:09

the two arm pressures in the denominator

1:09:13

and the higher of the uh two pressures

1:09:16

in each leg which is a normal. Now the

1:09:21

normal is is one between one and.9 is

1:09:26

borderline abnormality. you need to

1:09:28

exercise a patient and find whether it's

1:09:31

increasing or not the ankle break index.

1:09:34

Now if it is below than 0.9 then it's

1:09:37

diagnostic of peripheral vascular

1:09:39

disease. The nice thing about the test

1:09:40

is that it is reproducible. It's not

1:09:44

it's it imparts objectivity to the

1:09:47

diagnosis of peripheral vascular

1:09:49

disease. You don't rely on the symptoms.

1:09:51

Remember the symptoms is either absent

1:09:53

or they are atypical. you get some

1:09:57

nagging pain in the leg, not necessarily

1:10:00

related to effort, not necessarily

1:10:02

related by rest. So this kind of

1:10:04

subjectivity is nullified by the

1:10:08

measurement of the ankle brachial end.

1:10:10

If it's below 04 or 0.5, it's 4.4 or

1:10:15

less, then it means it's peripheral

1:10:19

vuscular disease. Now if it is above

1:10:21

1.4, Four, it means that the vessels are

1:10:25

abnormal, non-compressible because of

1:10:28

severe rigidity and or calcification

1:10:30

like in diabetics and patients with

1:10:32

renal failure. So under these

1:10:35

circumstances, you need to measure not

1:10:37

the ankle brachial index but the toe

1:10:40

brachial index. There is a special cup

1:10:42

for the toe and you measure the to the

1:10:44

toe pressure by the dock by Doppler

1:10:47

putting the Doppler probe on the pulp of

1:10:50

the toe and under these circumstances

1:10:53

you can measure the two pressure and

1:10:56

divide it by the higher of the two

1:10:58

brachial pressures and the cut off point

1:11:00

is 7 anything below 7 is is indicated of

1:11:06

now I tell you something a trick if you

1:11:08

are not interested in doing the ankle

1:11:11

brachial index and you are in and the

1:11:12

CCU you can put the finger oxymmetry on

1:11:15

the finger and on the big toe and a

1:11:19

difference of 2%

1:11:21

is as equal as an braal index which is

1:11:24

indicative of preferable coordin so this

1:11:27

is another method well documented well

1:11:29

validated not widely used but you can

1:11:31

use it if you like

1:11:34

now venus diseases you can get venus

1:11:37

insufficiency because of abnormality of

1:11:39

the valves You get swelling of the leg,

1:11:41

you get varicose veins and sometimes you

1:11:44

get hemocetin liberation. This hemoserin

1:11:46

will stain the lower limbs producing

1:11:49

lipo dermatosis

1:11:51

ulcerations may occur and you get the

1:11:54

blanche ulcer heal ulcer. In these

1:11:57

conditions sometimes the fibrosis which

1:11:59

occurs as a result of him of him

1:12:02

reposition results in contraction of the

1:12:04

limb giving an inverted sharp pain but

1:12:07

appearance something similar to paranal

1:12:09

muscular atrophy but in an eskeemic limb

1:12:12

as evidenced by eskeia and alserations

1:12:14

here. Now tissue loss can occur in the

1:12:17

form of the green as you can see here.

1:12:20

Now another question. This is the one

1:12:23

before the last. A 46 year old patient

1:12:26

of your partner arrives for an urgent

1:12:29

visit. He has recently been placed on a

1:12:31

new medication for congestive heart

1:12:33

failure management.

1:12:36

Which of the following is the most

1:12:38

likely new medication? Metropolin.

1:12:43

This is NGO edem and we we see it

1:12:47

infrequently but we see it particularly

1:12:49

with the widespread use of ACE inhibitor

1:12:52

and arbs. Now the guidelines is clear.

1:12:54

If you have it with ACE inhibitor you

1:12:56

stop the AC inhibitor you replace it by

1:12:58

ARBs. Does ARB produce anic edema? The

1:13:01

answer is yes but less frequently. And

1:13:04

if you have angitic edema you cannot use

1:13:06

arn. So you have to angotic edema occurs

1:13:10

in the soft tissues here. It's an

1:13:12

extension of articaria and it's

1:13:15

sometimes itchy because in the soft

1:13:17

tissues like the eyelids, the mouth in

1:13:20

the mouth, in the lips and in the

1:13:21

tongue. Sometimes it's life-threatening.

1:13:24

You don't need to treat it in the larger

1:13:26

majority of cases but it affects the

1:13:27

tongue and the larynx. You need to give

1:13:31

corticosteroids and anti-histics.

1:13:35

Now skin manifestations of

1:13:37

cardiovascular disease are protein but

1:13:39

let me concentrate on some of them.

1:13:42

Osgar Weber window syndrome

1:13:44

hemorrhagicia in the mouth it's not very

1:13:46

rare remember that this is frequently

1:13:48

associated with pulmonary arteriovenous

1:13:51

fistula. So this is associated central

1:13:53

blood cyanosis then you ought to think

1:13:55

of pulmonary arterian fist

1:13:58

this is not amoid this is amudarone this

1:14:01

is the skin of chronic amudarone the

1:14:03

therapies ley color the purple skin

1:14:06

affecting the face affecting the hands

1:14:09

affecting the chest wall osteiogenesis

1:14:12

imperfecta the the scalera is thinned

1:14:15

out so the vitrius appears behind it and

1:14:18

this is commonly associated with

1:14:19

connective tissue diseases named The

1:14:21

mitro valve prolapse, aortic dilation,

1:14:23

pulmonary artery dilation and aortic

1:14:26

dissection. Temporal arthritis you treat

1:14:29

first, you biopsy second. Although

1:14:32

nowadays biopsy is not invoked, biopsy

1:14:36

will result sometimes in false positive

1:14:38

or false negative results because of the

1:14:40

segmental effects of the disease. Ultra

1:14:43

sonography can be very helpful. We chose

1:14:45

the halo sign of edema around the vessel

1:14:48

and a segmental narrowing with diffuse

1:14:52

affection of the temporal artery and

1:14:54

that might be diagnostic. You don't need

1:14:56

biopsy in the large majority of cases.

1:14:58

Carcinoid purple huge discoloration

1:15:01

affecting of the right sided of the head

1:15:03

the right side of the right sided of the

1:15:05

right sided valves occasionally the left

1:15:08

side because of patent for and then this

1:15:10

picture is very important. This is a

1:15:13

myoid. You get pera in the eyelids. You

1:15:15

get raccoon eye.

1:15:22

You get a large tongue. You get

1:15:24

indentations of the tongue being from

1:15:25

the mouth. We know that this patient is

1:15:28

having amyrosis. We know now that there

1:15:30

is definitive treatment for transit

1:15:32

amidosis as well as for a amidosis.

1:15:36

Zanthasmus in the young think of

1:15:38

hypocria. Look for tubular zeneroma,

1:15:41

plenaros xenthoma, palmer zenthoma and

1:15:43

tubular xenoma. So these are important

1:15:46

things to look at.

1:15:49

The stigmata of infective endocarditis.

1:15:52

I know that the the cardiac department

1:15:54

of tyro university is very active in

1:15:57

endocarditis. You don't see that because

1:15:59

you are treating these patients in the

1:16:01

appropriate way. But when whenever these

1:16:03

cases are neglected or whether when they

1:16:05

are recurrent like in in injection

1:16:10

used patients you get splinter

1:16:12

hemorrhages. But an important point here

1:16:14

the splinter hemorrhage of the of

1:16:16

infective induces does not reach the

1:16:18

edge of the nail. I will show you

1:16:21

splinter hemorrhages common cause of

1:16:22

splinter commonest cause of splinter

1:16:24

hemor is actually trauma. And the way

1:16:28

you differentiate them is that in trauma

1:16:30

it reaches the age of eight. I will show

1:16:32

you a picture now and in bacteria and

1:16:34

ducatis it's usually proximal to the

1:16:37

edge of the knee you get mucosal pera

1:16:40

you get osar's node you get jane waist

1:16:42

node use which are painless in contrast

1:16:45

to osner nodes which are painful now

1:16:47

this is the traumatic the common type of

1:16:51

splinter hemoris is traumatic and

1:16:52

reaches almost the age of the knee and

1:16:55

this is not bacterial inocarditis

1:16:58

now this is the last question and I'll

1:17:00

be you finishing up that unless

1:17:02

professor

1:17:04

yesterday he has some question I'll be

1:17:06

happy to answer them it's now one and a

1:17:08

half hour I was very fast I apologize

1:17:11

for that but anyhow I think you will be

1:17:15

having the fun of criticizing what I did

1:17:17

I hope you I satisfied your ambition a

1:17:21

26 year old patient referred after

1:17:24

presenting to his orthalmologist by the

1:17:27

following look at the picture he the

1:17:30

question is about what is the next best

1:17:32

imaging method for assessment of this

1:17:35

patient MRI echo CT or the plex real

1:17:39

this is a suboxitated islands now I

1:17:44

think in kai university they are fond

1:17:46

with mafan syndrome and I don't know

1:17:49

where they are bringing these patients

1:17:51

in every examination we find mafan

1:17:53

syndrome but that's competence no doubt

1:17:56

about it now the diagnosis of maran

1:17:58

syndrome is resting now on the revised

1:18:01

Gent criteria. Gent is a is a city in

1:18:04

Belgium.

1:18:06

Very wise people collected there and put

1:18:09

criteria which has been revised several

1:18:11

times. The revision results in

1:18:13

subdivision

1:18:15

by forating patients with Maran syndrome

1:18:18

into two categories. Those with positive

1:18:20

family history and those with negative

1:18:23

family history. And those with positive

1:18:25

family history need to have aortic

1:18:28

radication or

1:18:31

ectopia lentis or a score of seven. The

1:18:36

score of seven or more we are talking

1:18:39

about the various manifestations of

1:18:41

maran syndrome. Increase the span,

1:18:43

increase the height, high arched pallet,

1:18:45

high foot deformity, dural easia, uh the

1:18:50

finger

1:18:52

wrist sign and so forth. If you get

1:18:54

seven or more of that or if you get

1:18:56

aortic root dilation or if you get

1:18:59

ectopia that's enough with a positive

1:19:02

family history but the majority of

1:19:04

patients you don't have a family

1:19:05

history. So these are the criteria in

1:19:07

the absence of a family history. You

1:19:09

need to get aortic dilotation plus

1:19:12

ectopentis or aortic dilutation plus

1:19:16

fibbrin mutation or aortic dilotation

1:19:19

plus score equal or above seven or you

1:19:22

get ectopia and fibbrin mutation. What's

1:19:25

fibbrin? Fibbrarian is a protein which

1:19:28

protects the connective tissue matrix.

1:19:31

But more importantly

1:19:34

it inhibits the transforming factor

1:19:38

which is transforming

1:19:40

growth factor beta and if you get

1:19:43

mutation of the fabrielin gene then the

1:19:46

signal from the transforming growth

1:19:48

factor beta will very active and that's

1:19:52

the reason behind digesting the

1:19:54

connective tissue elastic and color

1:19:57

tissue of the aorta and other large

1:19:59

vessels and resulting in aortic ization

1:20:01

and or the section. So I apologize for

1:20:04

being too long but I think I had give

1:20:07

you some pearls. There are other pearls

1:20:10

of course but that will be unfolded in

1:20:12

the coming lectures in cardiology. Thank

1:20:14

you very much. Have a good night and uh

1:20:17

I will be happy to answer any responses

1:20:19

any criticism any questions and so

ST elevation meard infection stable

1:21:24

angina particularly in the light of the

1:21:26

newly published eskeemia trial and two

1:21:31

1:21:33

because that's the fashion nowadays. And

1:21:35

1:22:10

Ahmed shahhata he's now very expert in

1:22:13

CT to talk about CT and then professor
