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.
右心室黏液瘤非常罕见。据我们所知，日本文献中仅报道过23例。一名76岁男性因咳嗽和呼吸困难入院。通过超声心动图和心血管造影，我们在右心室流出道发现一个异常的漂浮肿物。数字减影血管造影显示，肿物持续嵌顿于肺动脉，导致左主肺动脉完全闭塞，右肺动脉近乎梗阻。此外，他有黏液瘤的全身症状，血清白细胞介素-6水平达41.7 pg/ml。在体外循环下，我们挽救了右心室至右肺的流出道，切除了起源于右心室间隔并延伸至双侧主肺动脉的肿瘤。
