A 66-year-old woman who had had coughing and worsening dyspnea for 3 weeks was admitted to our hospital. Echocardiography showed a solid round mass (72×49 mm in diameter) attached to the tricuspid septal annulus with a short stalk. A right atrial myxoma was suspected and operation was performed under cardiopulmonary bypass after heart failure symptoms subsided. The tumor was extirpated along with the tricuspid valve annulus. We performed reconstruction of the tricuspid annulus, tricuspid valve replacement with a bioprosthetic valve and pacemaker implantation. The histopathologic diagnosis was myxoma. The postoperative course was uneventful, and no recurrence has been noted for 1 year after surgery.
