Abstract Details

Cardiac Calcified Amorphous Tumor: An Unusual Etiology for Recurrent Cardioembolic Strokes
Cerebrovascular Disease and Interventional Neurology
P3 - Poster Session 3 (5:30 PM-6:30 PM)

To report a patient with recurrent cardioembolic strokes, in whom an underlying calcified amorphous tumor (CAT) of the heart was detected as the etiology, 2 years after initial presentation.
CAT of the heart is a rare intracavitary cardiac mass characterized histologically by amorphous fibrinous material and calcification. It has a tendency for embolism. We use this illustrative case to bring awareness for this rare entity and utility of advanced cardiac imaging.

An 87-year-old woman with recurrent recent strokes was evaluated for her 5th stroke. Her neuroimaging had suggested an embolic etiology, but routine cardiac workup had not identified a  source. After her 5th stroke happened despite being on anticoagulation, a trans-esophageal ECHO (TEE) was done followed by cardiac MRI.

TEE and MRI showed a left atrial non-enhancing calcified mass attached by a stalk to the interatrial septum suspicious for CAT. The tumor was surgically resected. Histological examination showed nodular amorphous calcification against the background of degenerating fibrinous material consistent with CAT. The immediate post-operative period was uneventful, and the patient was discharged to a rehabilitation facility on aspirin monotherapy.

CAT is a rare cardiac tumor, and its presence is suggested by the presence of calcification of an intracardiac mass on cardiac imaging. The presence of mitral annular calcification (MAC) and renal disease can be additional clues to CAT being the cause for an intracardiac mass, which can then be identified by advanced cardiac imaging. A definitive diagnosis can be made only on pathology, and the definitive treatment is surgical.  MAC-related CAT can grow rapidly, has a high embolic risk, and should be removed expeditiously to prevent embolic strokes, even in asymptomatic individuals.
