With all murmurs the sound begins at the involved valve and radiates along the axis of fluid movement during the murmur. Mitral stenosis is lower pitch from lower filling pressure starting sooner and being constant. Reversing blood flow across the incompetant aortic valve takes time to crecendo. If these were hard and fast rules we would not need echocardiograms now would we.

@kirkferentzrocks M2 in Omaha here... I'm not sure if it's too late, but what we've been told throughout our Cardio class is look at where you're listening to the murmur. Aortic regurgitation (AR) will be heard at the sternal border whereas mitral stenosis(MS) will be heard at the apex. Also MS is a low pitched rumble whereas AR is a high-pitched/ blowing sound.

P.S. Huge a Hawkeye fan so I had to help a fellow one out...

@kirkferentzrocks lol...i was just thinking the same thing. M2 in boston

[kirkferentzrocks]

how can you tell the difference between this and the mitral murmur? Both sounds occur right after S2, or in sync with S2, so it's really hard to tell the differnence... I am only an M2 in chicago fyi, so I havnt had alot of experience yet. Thanks for any help!!

FYI: Aortic regurgitation occurs during "diastole". there are NO abnormal sounds during systole when blood is going from LV into Aorta. but during "diastole" blood flows back from high pressure Aorta back into LV causing a "blowing" murmur with a high pitch "swishing quality" which is heard over the LV.
