Although cardiac myxoma is rare, it is the most common primary cardiac tumor. Seventy-four cases of cardiac myxoma that were surgically treated in our center between August 1980 and February 2005 were retrospectively reviewed. The mean patient age was 50.4 +/- 15.0 (range 7-80) years, and 53 patients (71.6%) were female. The most common preoperative symptom, occurring in 44 patients, was dyspnea. The interval from onset of symptoms to surgery was 9 months. Seventy cases were located in the left atrium, 3 in the right atrium and 1 in the right ventricle. The myxoma in the right ventricle could not be resected completely, due to severe infiltration. Cardiopulmonary bypass and aortic cross clamp times were 100.4 +/- 37.1 and 64.8 +/- 29.8 minutes, respectively. There were no hospital deaths, and 7 patients suffered from postoperative complications including atrial fibrillation in 2 cases. During the follow up period (mean 105.7 +/- 73.6 months), there was no tumor recurrence and 6 late deaths that were not related to the underlying tumor. There was no evidence of tumor growth in the cases with incomplete resection during the 14-month follow-up. In conclusion, in this study there was no recurrence of tumors after complete resection and surgical resection is considered to be the curative method of treatment for cardiac myxoma.
