Identify the right pulmonary artery.

Which mitral regurgitation jet direction is most consistent with hypertrophic obstructive cardiomyopathy?

Show Suggested Answer Hide Answer
Suggested Answer: B

Comprehensive and Detailed Explanation From Exact Extract:

In hypertrophic obstructive cardiomyopathy (HOCM), systolic anterior motion (SAM) of the anterior mitral leaflet causes posteriorly directed mitral regurgitation (MR) jets. The abnormal anterior leaflet motion leads to incomplete leaflet coaptation and regurgitant flow directed toward the posterior left atrium.

Anterior jets are seen with posterior leaflet abnormalities. Central jets are seen in functional MR. Medial jets are less common and depend on leaflet pathology.

This jet direction is an important echocardiographic feature distinguishing HOCM-related MR and is outlined in ASE valvular heart disease and cardiomyopathy guidelines12:ASE Valvular Regurgitation Guidelinesp.220-22516:Textbook of Clinical Echocardiography, 6ep.350-355.

Wait, is it really the central jet? I thought it was posterior.

Definitely think it's the anterior jet for HOCM.

The right pulmonary artery is on the left side of the image!

I’m pretty confident that the jet direction for hypertrophic obstructive cardiomyopathy is central, but I need to double-check that with my notes.

For the right pulmonary artery, I feel like it’s the one that branches off the main pulmonary trunk, but I can't recall the exact position in this image.

I remember practicing mitral regurgitation jets, and I think the direction related to hypertrophic obstructive cardiomyopathy is usually anterior, but I could be mixing it up.
