説明

Between March 1976 and February 1996, 17 patients underwent surgical treatment for cardiac myxomas. There were 5 men and 12 women with a mean age of 55 years (range: 22 to 78 years). The location was the left atrium in 13, right atrium in 2, right ventricle in 1 and multiple locations in 1. Since 1978 the standard operative method to treat left atrial myxoma has been a biatrial approach with complete removal of cardiac myxoma and partial resection of the atrial septum. There were no perioperative deaths, but 1 patient had a permanent pace-maker implantation, 2 had transient atrial fibrillation during the early postoperative period, and 1 had acute pulmonary edema after resection of a right ventricular myxoma. There were two late deaths, not related to cardiac event and one recurrence with multiple myxomas. Overall with long term follow-up, the actual survival rate at 10 years was 75% (n=6), with a mean follow-up of 7.1 years, with a 100% follow-up ratio (17 patients). We conclude that the biatrial approach with complete removal of the left atrial myxomas and partial resection of the atrial septum is one of the best procedures for surgical treatment.
