Cardiac hemangioma: a report of two cases and review of the literature.

Cardiac hemangioma is extremely rare. We encountered two patients with cardiac hemangioma detected by thoracic echocardiography during a medical checkup. In the first case, transthoracic echocardiography revealed a pedunculated tumor in the left ventricle. Selective left coronary angiography demonstrated that the main feeding artery of the tumor arose from the third diagonal branch of the left anterior descending coronary artery. In the second case, thoracic and transesophageal echocardiography showed an oval tumor arising from the right atrium. Both tumors were successfully resected. Histopathological examination revealed that one of the tumors was a capillary hemangioma and the other was a mixed capillary and cavernous hemangioma. After operation, both patients had an uneventful recovery without any complications.
