Myxomas account for the vast majority of heart tumors in adults. About 70% originate in the left atrium, while about 10% of these are reported to originate in the right atrium. A 70-year-old man with dyspnea, was found to have a giant right atrial mass by echocardiography, and tumor resection was performed under cardiopulmonary bypass (CPB) through a median sternotomy. At weaning from CPB the patient was hemodynamically unstable. Intraoperative echocardiography showed severe tricuspid regurgitation (TR), and tricuspid annuloplasty was performed. The postoperative course was uneventful and histopathological examination confirmed that the tumor was a myxoma. It is important to keep in mind that regurgitation of the atrio-ventricular valve might occur after resection of atrial myxoma.
