We report a case of a giant right atrial myxoma mimicking the right ventricular tumor. The 75-year-old patient underwent cardiac surgery, and the tumor was excised along with the stalk. Tricuspid valve annuloplasty was performed before closure of the right atriotomy. The tumor may have caused intraventricular stenosis, hepatic dysfunction, and progressive fatigue as a result of low cardiac output. This case is of special interest because the myxoma was very large compared with those ever reported, and a right atrial myxoma occupying the right ventricular cavity is rare.
我们报告了一例右心房黏液瘤酷似右心室肿瘤的病例。该 75 岁患者接受了心脏手术，肿瘤和蒂部一起被切除。三尖瓣环成形术在右心房切开术关闭之前进行。肿瘤可能导致心室狭窄、肝功能障碍和心输出量降低导致的进行性疲劳。该病例特别有趣，因为与以往报道的黏液瘤相比，该黏液瘤非常大，而且占据右心室腔的右心房黏液瘤非常罕见。
