Abstract
Myxomas are the most common tumors of the heart. They are frequently located in the left atrium and produce symptoms when they fragment and cause systemic emboli or when they interfere with cardiac valvular function and cause pulmonary congestion. Careful surgical management of these lesions should be curative with minimum early and late morbidity and mortality. Optimal operative technique emphasizes minimal manipulation of the heart before institution of cardiopulmonary bypass and aortic cross-clamping and careful examination of intracardiac chambers with meticulous removal of myxomatous debris. Using these techniques, 17 patients have been treated successfully at the Brigham and Women's Hospital. There were no operative deaths and no significant perioperative morbidity. Fifteen patients are asymptomatic, and one patient has minimal shortness of breath an average of 57 months after surgery. One patient died of leukemia 15 months postoperatively. No recurrent myxomas have been identified, and no patients have symptoms of other cardiac disease.
