Pedunculated hemangioma in the right ventricle.

We report a rare case of right ventricular hemangioma. In an asymptomatic 56-year-old man, echocardiography as a part of medical checkup demonstrated a pedunculated tumor, 1.0 x 1.3 x 1.5 cm, arising from the free wall of the right ventricle. No findings were seen of a feeding artery to the tumor or vascular blush in preoperative coronary angiography. Successful resection was done through right atriotomy under total cardiopulmonary bypass. The histological examination revealed capillary hemangioma. The postoperative clinical course was uneventful, but requires careful follow-up for possible coronary cardiac fistula. This is the fifth case of right ventricular hemangioma, to our knowledge, ever reported in Japan.
