We have reported a very rare case of biatrial ball thrombosis.
A 71-year-old man was admitted with cardiac failure and tachycardia of atrial fibrillation. He had a long history of atrial fibrillation without anticoagulation therapy. Cardiac failure and tachycardia were improved with medical therapy. Echocardiography showed biatrial giant tumors. Removal of the tumors was carried out with the aid of cardiopulmonary bypass. Pathological examination revealed that the right and left atrial tumors were both organized thromboses.
His postoperative course was uneventful, and he was discharged on the 17th postoperative day. Only atrial fibrillation is considered to have had an important role in the etiology of biatrial thrombosis. Therefore we suggest that he should be kept on anticoagulation to avoid recurrence of intra-cardiac thrombosis.
