[Successful resection of the right atrial myxoma with excessive tumor vascularity in a elderly patient].

A 72-year-old female underwent successful resection of a giant right atrial myxoma. The patient had slight cough with abnormal cardiac silhouette and elevated ESR. The diagnosis of right atrial myxoma was established by echocardiography and angiography. Venacavography revealed huge mass which occupied in the entire right atrium. This tumor was perfused by well developed feeding arteries arising from both right and circumflex coronary arteries, and showed rich tumor vascularity. This tumor was resected with the interatrial septum and the free wall of the right atrium which were attached with tumor. Interatrial septal defect was closed with a Teflon fabric patch and the defect of right atrial free wall was approximated by direct closure with Z-plasty. Postoperative course was uneventful. Pathological examination showed myxoma without invasion into the resected septum and atrial wall. It is important to prevent tumor embolization to the pulmonary artery or strangulation into the right ventricle during surgery on this type of huge right atrial myxoma.
