Cerebral Embolism due to a Large Papillary Fibroelastoma arising from the Coumadin Ridge.

A 70-year-old woman developed acute cerebral infarction. Transthoracic echocardiography showed a large mobile mass in the left atrium, suggesting cardiac myxoma as the most likely diagnosis. Surgical exploration revealed a papillary fibroelastoma originating from the coumadin ridge, which is fairly rare but important as a source of cerebral embolization.
