Mobile thrombus originating from densely calcified mitral annulus with cerebral embolism

Abstract

Mitral annular calcification (MAC) has been considered a predisposition and an association of thrombo-embolic disease. Superimposed thrombus on MAC is under-appreciated as a potential cause of systemic thrombo-embolism. This report describes an elderly gentleman, who had recurrent cerebral embolism and in one of the episodes, a large mobile thrombus was detected on the ventricular surface of calcified mitral annulus. The thrombus disappeared after initiation of anti-coagulation.
