We report surgical treatment of 22 patients with primary cardiac myxomas, including 17 left atrial (LA), 3 right atrial (RA), 1 left ventricular and 1 right ventricular myxomas. Eighteen patients manifested congestive heart failure, and an embolic episode was observed in 5 patients preoperatively. Inflammatory laboratory findings were observed in 16 patients. One case of RA myxoma was complex cardiac myxoma. A transverse biatrial approach was useful for removal of large LA myxomas and when the attachment of the tumor was unconfirmed preoperatively. There were no hospital deaths. Stroke occurred in 1 and supraventricular arrhythmia in 3 patients in the early postoperative period. There were 2 late deaths unrelated to cardiac myxomas. No signs of recurrence have been observed.
