摘要

A 64-year-old female, admitted because of severe dyspnea on exertion and facial edema, showed echocardiographic findings of a large tumor in the right ventricle (RV). Echocardiography revealed a cardiac mass extending from the RV across the tricuspid valve into the right atrium, synchronized with the cardiac cycle, and severe tricuspid regurgitation was apparent. The mass was removed under cardiopulmonary bypass. It measured 7 x 5 x 5 cm with diffuse superficial calcification and arose from the posterior wall of the RV, just under the tricuspid valve ring, with a short pedicle. During the same procedure, after the successful excision of the tumor, small atrial and ventricular septal defects were found that had been caused by the tumor and these were closed directly. The tricuspid valve was repaired with valvuloplasty, chordoplasty and annuloplasty. The microscopic findings were of typical myxoma; however, a right ventricular myxoma protruding into the right atrium is exceedingly rare.
