Figure 3 Case 1. Gross autopsy photographs. Left, Mitral valve viewed from left atrial aspect showing presumed source of embolus from exposed calcium near the posteromedial commissure (arrow). AML = anterior mitral leaflet. Right, Unroofed left main coronary artery at the bifurcation of the left anterior descending and circumflex arteries showing occlusion by a large calcific embolus (arrow).

Figure 4 Case 2. Left, Short-axis image of transthoracic echocardiogram showing a large protruding area of mitral valvular calcification, approximately 8 mm in diameter, along the medial commissure. Right, Artist representation of echocardiographic image. AML = anterior mitral leaflet; C = calcification; PML = posterior mitral leaflet.
