Diastolic Heart Murmurs (5 star!!!) Flashcards
4 diastolic heart murmurs
- aortic regurgitation
- pulmonic regurgitation
- mitral stenosis
- tricuspid stenosis
after what heart sound would diastolic murmurs be heard
S2
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
what can cause mitral stenosis
rheumatic fever; chronic M. stenosis can result in left atrial dilation
what can enhance mitral stenosis murmur
maneuvers that ↑ LA return like expiration
immediate high-pitched, blowing diastolic murmur; decrescendo
aortic regurgitation
what can ↑ intensity of aortic regurgitation
hand grip–> anything that increases SVR or afterload
causes of aortic regurgitation (3)
- aortic root dilation (syphilis and Marfans)
- Bicuspid aortic valve
- rheumatic fever (or endocarditis)
2 classic signs seen with aortic regurg
- head bobbing
2. bounding pulses–> due to widened pulse pressure
left sternal border usually means which valve is being auscultated
pulmonic–> can hear both pulmonic or aortic regurg here
where is a PDA best heard?
left infraclavicular area–> loudest at S2
after what heart sound would diastolic murmurs be heard
