Abstract:
Myxomas are account for approximately half of primary cardiac tumors, and 75% cases originate in left atrium. We report our experience of a right atrial myxoma. A 68-year-old woman was referred to us due to anorexia, general fatigue and facial edema. Echocardiogram, computed tomography (CT), magnetic resonance imaging (MRI), and catheter angiocardiogram revealed a huge tumor in right atrium. The tumor was resected completely with the attached right atrial free wall under cardiopulmonary bypass. Pathological examination showed myxomatous tissue. Postoperative course was uneventful. She discharged the hospital on the 37th day after the operation, and is now doing well without any symptoms.
