Seven patients [six cases of left atrial myxoma, one case of right atrial myxoma] from 24 to 66 years of age [4 male and 3 female, mean age 48 years] underwent excision of atrial myxoma between 1982 and 1989 at Keimyung University Dongsan Medical Center. All patients presented with congestive heart failure, six with cardiac murmur, three with syncope, two with sinus tachycardia, one each with sinus arrhythmia, atrial fibrillation, pleural effusion, peripheral embolization. Symptoms were present from 1 month to 8 years before operation [mean 28 months], All tumors originated from atrial septum and pedunculated. The myxomas were successfully removed in all patients, either shaving them from atrial septum [n=3] or by excising a portion at normal atrial septum with tumor [n=4]. One case was replaced mitral valve with carbomedics-31mm due to severe mitral regurgitation. Follow up is current. No recurrent myxoma has been identified clinically or by echocardiography. In this series, excellent results were obtained by simple excision of the tumor, with or without a margin of normal atrial septum.
