ABSTRACT
Right ventricular myxoma is very rare. To our knowledge, only 23 cases in Japan have been reported in the literature. A 76-year-old male was admitted with complaints of cough and dyspnea. We found an abnormal floating mass in the right ventricular outflow tract by echocardiography and cineangiocardiography. The digital subtraction angiography showed that the following mass continuously lodged in the pulmonary artery with total occlusion of the left main pulmonary artery and near obstruction of the right pulmonary artery. Furthermore he had the constitutional signs of myxoma and the serum IL-6 level reached 41.7 pg/ml. Under extra-corporeal circulation, we salvaged the right ventricular outflow tract to the right lung, resecting the tumor, originated from the right ventricular septum and extended to bilateral main pulmonary arteries.
