The echocardiographic images mimicked a left atrial tumor. She had hypertension, and she had been taking amlodipine for 5 years. There was no audible murmur. The chest radiograph and electrocardiogram were normal. Two-dimensional echocardiography showed rheumatic valvular disease and a mobile mass in the left atrium that resembled a cyst or cor triatriatum sinister.
