A post-valvulotomy mid-systolic click correlates with sudden midsystolic posterior motion of the mitral valve apparatus on echocardiography.
Correlates post-valvulotomy click with mitral motion; single case leaves generalizability and practice implications open.
An echocardiographic correlate for a post-valvulotomy mid-systolic click is described. Simultaneous echocardiographic and phonocardiographic studies demonstrated that the click was temporally related to a sudden midsystolic posterior motion of part of the mitral valve apparatus. This temporal relationship suggests that the sudden change in position of portions of the mitral valve resulted in the loud midsystolic click. In our patient the sudden leaflet movement associated with the click was apparently a localized abnormality.
