Cardiac calcified amorphous tumor with mitral valve perforation: A case report

Cardiac calcified amorphous tumors are rare non-neoplastic intracavitary masses. Herein, we report a case of a 75-year-old woman who presented with dyspnea on exertion and multiple cerebral infarctions 3 months prior. Transthoracic echocardiography showed severe mitral regurgitation from the posterior mitral leaflet with valve perforation and severe mitral annular calcification. In addition, we observed a 13 mm mobile high echogenic mass, suggesting healed infective endocarditis. The mass was successfully resected, and the mitral valve was replaced with a bovine pericardial patch for the decalcified annulus. Histopathological examination confirmed cardiac calcified amorphous tumor; the postoperative course was uneventful. Mitral valve replacement and annulus patch repair effectively prevented postoperative recurrent systemic embolization.
