|---|
Mitral annular calcification (MAC) has been considered a risk factor for thrombo-embolic disease. Superimposed thrombus formation on MAC has not been well described as a possible underlying mechanism for this association. We report three patients with mobile left ventricular (LV) thrombus arising from the LV aspect of severe calcified mitral annulus in the setting of normal LV function, mitral valve function, and sinus rhythm.
