Primary intracavitary cardiac tumors: a review of 11 surgical cases.

During the past 14 years, 11 patients varying age from 27 to 68 years, had excision of primary intracavitary cardiac tumor: 7 had a left atrial myxoma, 1 a left ventricular myxoma, 1 a right ventricular myxoma, and 2 had a left atrial malignant mesenchymoma. Accurate diagnosis was made by angiocardiography in 8 patients. All patients underwent open heart excision of the tumor with the use of cardiopulmonary bypass. One of the 9 patients with a left atrial myxoma died postoperatively with recurrence of the tumor. The two patients with left atrial malignant mesenchymoma died 8 and 15 months after palliation. All surviving patients are asymptomatic without evidence of recurrence.
