Surgery of left atrial myxomas. Report of eleven cases and review of the literature

Abstract

Eleven patients with left atrial myxoma in a ten-year period were reviewed. They ranged from 16 to 69 years old. Eight patients were female. All tumors were located in the left atrium; one patient had multiple tumors. The main clinical presentation was congestive heart failure seen in eight patients. Ten patients had a correct pre-operative diagnosis. Echocardiography confirmed the diagnosis in seven patients, angiocardiography in two and cardiac catheterization in one. All tumors were successfully removed with the aid of cardiopulmonary bypass and using a right atriotomy and trans-septal approach. Two patients underwent concomitant saphenous vein aortocoronary bypass. There were no operative deaths. Excision of the tumor resulted in marked symptomatic improvement. There have been no recurrences. A review of the pertinent literature is presented.
