1

4 diastolic heart murmurs

1. aortic regurgitation
2. pulmonic regurgitation
3. mitral stenosis
4. tricuspid stenosis

2

after what heart sound would diastolic murmurs be heard

S2

3

rumbling late diastolic murmur with opening snap

mitral stenosis

*does not start at beginning of diastole; OS due to abrubt halt after rapid opening; stops b/c fused at leaflet tips

4

what can cause mitral stenosis

rheumatic fever; chronic M. stenosis can result in left atrial dilation

5

what can enhance mitral stenosis murmur

maneuvers that ↑ LA return like expiration

6

immediate high-pitched, blowing diastolic murmur; decrescendo

aortic regurgitation

7

what can ↑ intensity of aortic regurgitation

hand grip--> anything that increases SVR or afterload

8

causes of aortic regurgitation (3)

1. aortic root dilation (syphilis and Marfans)
2. Bicuspid aortic valve
3. rheumatic fever (or endocarditis)

9

2 classic signs seen with aortic regurg

1. head bobbing
2. bounding pulses--> due to widened pulse pressure

10

left sternal border usually means which valve is being auscultated

pulmonic--> can hear both pulmonic or aortic regurg here

11

where is a PDA best heard?

left infraclavicular area--> loudest at S2

12

after what heart sound would diastolic murmurs be heard

S2

13
