[Intramyocardial hemangioma of the right ventricle with successful resection--report of a case and review of the literature].
A 62-year-old man developed symptoms of heart failure. Echocardiography showed a dense mass arising from the free wall of the right ventricle and occupying about 75% of the right ventricular cavity. Selective coronary angiography demonstrated intense neovascularization of a cardiac neoplasm arising in the distribution of the right coronary artery. Under cardiopulmonary bypass the tumor was resected completely and the defect of the ventricular wall was repaired with Gore-tex (EPTFE) patch (area 7.5 X 5.0 cm). The size of the resected tumor was 10.0 X 9.5 X 3.4 cm and weighed 170 g. Histological examination of the tumor disclosed cavernous hemangioma. The post operative course was uneventful and the patient has remained asymptomatic after the surgery. To our knowledge, only 23 cases of intramyocardial or intracavital hemangioma were reported in the world literature and this may be the first report in Japan.
