[Cavernous hemangioma of the heart: report of a case]

Cavernous hemangioma of the heart is a very rare disease. A 57-year-old male patient was admitted due to frequent onset of dull chest pain, which had been occurring for about 1 year. The pain was not related to exercise and was not relieved with nitroglycerin. On echocardiographic examination, a tumor was shown in the outflow tract of the right ventricle and was confirmed with computer tomography. He underwent open heart surgery for resection of the tumor. After a median sternotomy and opening of the pericardial cavity, a reddish-brown-colored tumor, 3 cm in diameter, was found protruding from the epicardial layer of the right ventricular outflow tract. The tumor involved all layers of the ventricle and could be resected only with the help of the cardiopulmonary bypass technique. The defect in the right ventricle was repaired with a woven dacron patch. The patient recovered without incident after the operation, and experienced no chest pain during 7 months of follow-up. Histology showed it to be a cavernous hemangioma.
