Abstract

We present a case with posterior mitral valve prolapse exhibiting early closure of the aortic valve and protodiastolic extrasound. It seems that the forward stroke volume suddenly reduced during late-systole because of a late-systolic increase in severe mitral regurgitation and the aortic valve closing early in timing. The simultaneous observations of sound, mitral valve, and mitral inflow recordings suggest that the protodiastolic sound may be related to the rapidly returning motion of the posterior mitral leaflet and recoaptation with the anterior mitral leaflet.
