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 video shows a enlarged left ventricle with normal contractility. You can see regurgitant flow from the aorta into the left ventricle which causes the murmur.
