Systolic Murmurs (5 star!!) Flashcards Preview

Step 1 > Systolic Murmurs (5 star!!) > Flashcards

Flashcards in Systolic Murmurs (5 star!!) Deck (25):
1

6 systolic murmurs

1/2. mitral or tricuspid stenosis
3/4. Aortic or pulmonic stenosis
5. VSD
6. mitral valve prolapse

2

crescendo-decrescendo systolic murmur following ejection click

aortic stenosis

*ejection click due to abrupt halting of valve leaflets

3

where does aortic stenosis murmur radiate

carotids or heart base

4

MCC of aortic stenosis

bicuspid aortic valve

5

2 other causes of aortic stenosis beside bicuspid valve

1. chronic rheumatic valve dz
2. Syphilis

*could also be a cong. unicuspid valve

6

3 symptoms aortic stenosis can lead to

1. syncope
2. angina (chest pain w/ exertion)
3. dyspnea on exertion

* "SAD"

7

characteristic sign of aortic stenosis

pulsus parvus et tardus

8

holosystolic harsh sounding murmur heard best at tricuspid area

VSD

9

what can accentuate a VSD murmur

hand grip and inspiration

* heard best in tricuspid area

10

late systolic crescendo murmur

mitral valve prolapse

11

what noise is heard with MVP

midsystolic click! (due to tensing of chordae tendinae)

12

3 causes of MVP

1. myxomatous degeneration
2. rheumatic fever
3. chordae rupture

13

what can enhance MVP murmur

standing or valsalva--> anything that enhances venous return

14

holosystolic, high-pitched "blowing murmur"

mitral or tricuspid regurgitation

*these immediately follow S1--> aortic stenosis and MVP both have start a little after S1

15

holosystolic, radiates to right sternal border

tricuspid regurgitation

16

holosystolic, radiates toward axilla

mitral valve regurgitation

17

MCC of mitral regurgitation

rheumatic heart dz

18

2 other causes of mitral regurg other than the MC

1. ischemic heart dz
2. left ventricular dilation

19

IV drug users usually cause what kind of valvular damage and which one

tricuspid regurgitation--> infective endocarditis from dirty drugz

20

enhances mitral regurg

hand grip or squatting (increased SVR)

21

enhances tricuspid regurg

inspiration (increases venous return)

22

MC valvular lesion

MVP

23

aortic stenosis at around age 40--> cause?

biscuspid aortic valve

24

aortic stenosis after age 60?

senile degenerative calcification

25

RV dilation can cause

tricuspid regurgitation
