Giant right atrial myxoma associated with tricuspid regurgitation.
A 55-year-old woman presented with dyspnea on effort for half a year that had progressed with time. Echocardiography showed a giant spherical mass (6 cm diameter) in the right atrium occupying almost the entire space of the atrium. The mass was attached to the interatrial septum with a wide base. There was moderate to severe tricuspid regurgitation. Emergency operation was performed via median sternotomy. Under cardiopulmonary bypass, the tumor was excised with the interatrial septum where the tumor was arising. The defect was closed using an autologous pericardial patch. Tricuspid annuloplasty was carried out with no residual tricuspid regurgitation.
