Abstract

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.
