Question

Possible secondary echocardiographic/Doppler findings in patients with severe chronic mitral regurgitation include all the following EXCEPT:

A. Increased mitral valve E velocity
B. Increased peak aortic valve velocity
C. Increased right ventricular dimension
D. Shortened time too peak velocity of the right ventricular outflow tract

Answer 1

Possible secondary echocardiographic/Doppler findings in patients with severe chronic mitral regurgitation include increased mitral valve E velocity, increased right ventricular dimension, and shortened time to peak velocity of the right ventricular outflow tract. The finding that is NOT typically seen is increased peak aortic valve velocity.

Step-by-step explanation:

In patients with severe chronic mitral regurgitation, secondary echocardiographic/Doppler findings may include:

1. Increased mitral valve E velocity: This is a finding that is commonly associated with severe mitral regurgitation. As the regurgitant volume increases, there is a higher E velocity on the Doppler echocardiogram.
2. Increased right ventricular dimension: In severe mitral regurgitation, the volume overload on the left side of the heart can lead to enlargement of the right ventricle.
3. Shortened time to peak velocity of the right ventricular outflow tract: This is a finding that can be seen in severe mitral regurgitation due to the increased flow through the pulmonary artery.

The finding that is NOT typically seen in patients with severe chronic mitral regurgitation is increased peak aortic valve velocity.
