Question

Doppler evidence of constrictive pericarditis includes:

A. Increased peak velocity across the mitral valve with inspiration
B. Increased peak velocity across the aortic valve with inspiration
C. Increased peak velocity across the mitral valve with expiration
D. Increased peak velocity across the tricuspid valve with expiration

Answer 1

The increased peak velocity is typically observed across the tricuspid valve with expiration in Doppler evidence of constrictive pericarditis.

Step-by-step explanation:

In Doppler evidence of constrictive pericarditis, the increased peak velocity is typically observed across the tricuspid valve with expiration. This is due to the impaired filling of the right ventricle. Constrictive pericarditis is a condition where the pericardium, the sac surrounding the heart, becomes thick and fibrotic, restricting the heart's ability to expand and fill with blood properly.
