Abstract
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.
<Learning objective: Calcified amorphous tumor (CAT) is a risk factor for systemic embolism. Cardiac CAT
destroying the mitral valve tissue and causing mitral valvular disease have been scarcely
reported. We present a case of cardiac CAT with mitral valve perforation and suspected
systemic embolization, treated successfully through mitral valve replacement and calcified
lesion coverage by surgical resection and patch repair.>
