Atrial myxoma: report of 24 operations using the biatrial approach.

Between October 1978 and June 1993, 24 consecutive operations for atrial myxoma were performed on 23 patients at the Damascus University Cardiovascular Surgical Center, using the biatrial approach. Fifteen of the patients were female; ages ranged between 4 and 71 years. Nineteen patients had symptoms of left and 3 of right atrioventricular obstruction. One patient presented with a cerebrovascular accident, and another with recurrent emboli to the lower extremities. Ten patients had constitutional manifestations. Diagnosis was established preoperatively in all patients by echocardiography with or without angiocardiography. Twenty-one patients had left atrial myxoma, 1 of whom had a double lesion. Two patients had right atrial myxoma; in 1 of them it extended to the left atrium. This last patient had the only recurrence in the series, which was removed 7 years after the initial operation. All tumors were excised with a wide margin of full-thickness septum. Four patients had concomitant mitral valve reconstruction. There was no hospital mortality, and follow-up did not reveal any other complication related to the operation.
