An incision was made in the left atrium, and a soft, firm, and friable mass was founded on the atrial surface of the anterior leaflet of the mitral valve which was easily removed (Figure 2).
Histological examination showed dense calcification (shredded due to no decalcification) (arrows) in a background of amorphous degenerating fibrinous material (hematoxylin and eosin stain; x40).
