[A case of right ventricular hemangioma].

We report a case of right ventricular hemangioma which is extremely rare. It was situated on the anterior wall of the right ventricle and protruded into the out flow tract. Aortography revealed that the main feeding artery was the conus brunch. Operation was done under cardiopulmonary bypass. The tumor was situated between LAD and RCA and resected incompletely, because of the fear that complete removal would occlude blood flow of both LAD and RCA. Histological examination disclosed intramuscular hemangioma. The postoperative course was uneventful. To our knowledge, this is the second resected case in the Japanese literature and the eighth case in the world literature.
