Flashcards in Valvular Heart Disease Deck (38):
1

Most common cause of aortic stenosis

Degenerative/senile/sclerocalcific AS

2

Moat common congenital heart valve defect with male predominance

Bicuspid aortic valve disease

3

Severe LV obstruction is defined as

Mean systolic pressure gradient >40mmhg with normal CO
effective aortic orifice area < 1cm2 or < 0.6cm2/m2 BSA

4

In the early course of severe AS - indicates reduced compliance of the hypertrophied LV

Elevated LV EDP + preserved EF

5

In late AS deterioration of contractile function is due to

Excess afterload: dec CO and LV- aortic pressure gradient, inc in the mean LA, PA, and RV pressure

6

Increased oxygen demand due to hypertophied LV in AS causes

Angina

7

Cardinal symptoms in AS

Angina, syncope, dyspnea (AS-D)

8

Symptoms of LV failure

Orthopnea, PND, pulmo edema

9

Slow rise of peripheral arterial pulse to a delayed sustained peak in AS

Pulsus parvus et tardus

10

Synchronous or paradoxically split s2 in AS

Delayed closure of aortic valve as the LV systole becomes prolonged

11

Murmur in AS

Midsystolic ejection murmur loudest at the base of the heart most commonly in 2nd right ics

12

AS Severity in 2D echo

Severe:< Icm
moderate:1-1-5cm2
M i I d:1.5-2 cm2

13

In Aortic Stenosis average time Of death after onset Of Symptoms( in the absence of surgical treatment)

Angina:3 years
Syncope:3 years
Dyspnea:2 years
C H F :1.5-2 years

14

most common cause Of death in AS

CHF

15

major hemodynamic compensation in Aortic regung

increased LV End Diastolic Volume(preload)

16

Laplace's law in Aortic Regurg:

Left vent dilation increases left vent systolic tension required to develop any given level of systolic pressure

17

rapidly rising 'water hammer' pulse which collapses suddenly as arterial pressure falls during late systole and diastole in AR

Corrigan's pulse

18

capillary pulsations with alternate Flushing and paling Of the skin at the root of the nail in AR

Quincke's pulse

19

Booming pistol shot pulse over the Femoral arteries

Traube's sign

20

To and fro murmur audible with light compression of the steth over the femoral artery

Duroziez's sign

21

Aortic Regurgitation murmur

high pitched blowing de crescendo diastolic murmur heard best over the 3rd ICS left sternal border

22

soft rumbling middiastolic bruit in AR

Austin Flint murmur

23

Optimal Time of Surgery in AR

After Onset of LV dysfunction but BEFORE the onset of severe symptoms

24

Leading cause of mitral stenosis

Rheumatic Fever

25

Low pitched diastolic murmur following the OS

mitral stenosis

26

Pansystolic murmur produced by Functional T R at the left Sternal border accentuated by inspiration and diminished by Forced expiration or valsalva

Carvallo 's sign

27

Carvallo 's sian in mitral Stenosis indicates?

Severe Pulmonary Hypertension

28

High- pitched diastolic de crescendo blowing murmur along the left Sternal border resulting from dilatation of the pulmonary value ring and occurs in patients with mitral valve disease and Severe pulmonary hypertension

Graham Steel murmur

29

most sensitive and specific non invasive method in diagnosis mitral Stenosis

2 D echo

30

Malar Telangiectasia

Severe mitral Stenosis

31

Anacrotic pulse

AS

32

Bifid/ Bisferiens pulse

Hypertrophic Cardiomyopathy, AR

33

Pulsus bigeminus

pvc's

34

Pulsus alternans

Severe HF

35

Normal B P difference between arms

< 10 mmHg

36

conditions causing delay in mv closure causes

reversed Split S2

LA myxoma
LBBB

37

Diastolic sound

Opening Snap
pericardial knock
Tumor plop
S4

38

most common Valvular involvement in carcinoid syndrome

Pulmonic Valve
