Mild Aortic Stenosis Moderate and Regurgitation Lesson #695
The patient was sitting leaning forward during auscultation.
Description
This lesson discusses moderate aortic stenosis combined with mild aortic regurgitation in a patient with rheumatic heart disease.
S1 is normal, and S2 is unsplit. An aortic ejection click occurs in systole followed by a diamond-shaped systolic murmur. A high-pitched decrescendo murmur fills the first two thirds of diastole.
In the cardiac animation video, you can see a thickened left ventricle and thickened aortic valve leaflets. Moderate turbulent blood flows across the aortic valve in systole and a mild regurgitant turbulent flow into the left ventricle occurs in diastole. These turbulent blood flows cause the systolic and diastolic murmurs.

Mild Aortic Stenosis Moderate and Regurgitation
In the animation, observe a thickened left ventricle and thickened but mobile aortic valve leaflets. There is moderate turbulent flow across the aortic valve in systole and mild regurgitant turbulent flow into the left ventricle in diastole.
The turbulent blood flow causes the systolic and diastolic murmurs.
