|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.
