Aortic Regurgitation Lesson #642
The patient was sitting leaning forward during auscultation.
Description
Aortic regurgitation produces a decrescendo murmur starting early in diastole. The first and second heart sounds are normal. The decrescendo murmur is high-pitched.
Aortic diastolic murmurs can be heard at the right sternal border, third and fourth intercostal spaces.
The anatomy video shows an enlarged left ventricle with normal contractility. Observe the regurgitant flow from the aorta into the left ventricle, which causes the murmur.
