Aortic Regurgitation (Decrescendo Diastolic Murmur)

This is an example of a decrescendo murmur starting early in diastole.

The first and second heart sounds are normal.

The decrescendo murmur is high pitched. The anatomy tab shows a enlarged left ventricle with normal contractility. You can see regurgitant flow from the aorta into the left ventricle which causes the murmur.
