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.
黏液瘤占成人心脏肿瘤的绝大多数。约70%起源于左心房，而据报道其中约10%起源于右心房。一名70岁男性因呼吸困难，经超声心动图检查发现右心房有巨大肿块，遂通过正中胸骨切开术在体外循环（CPB）下进行肿瘤切除。在脱离CPB时，患者血流动力学不稳定。术中超声心动图显示严重三尖瓣反流（TR），遂进行三尖瓣环成形术。术后病程平稳，组织病理学检查证实肿瘤为黏液瘤。必须牢记，心房黏液瘤切除术后可能会发生房室瓣反流。
