Total endoscopic resection of left atrial myxoma.

Myxoma is a rare benign cardiac tumor occurring mostly in the left atrium. Surgical removal of the lesion is indicated to avoid intracardiac obstruction and systemic embolism. We performed surgical removal of left atrial myxoma by total endoscopic surgery without robotic assistance in 40 patients. In this technique, surgical instruments are inserted through four incisions with trocars < 1.5 cm in size. The mean cardiopulmonary bypass and aortic cross-clamp times were 141.3 ± 33.7 and 74.8 ± 28.3 min, respectively. There were no cases of death or conversion to median sternotomy, and the postoperative hospital stay was 7.2 ± 5.0 days. No cases of tumor recurrence or septal leakage occurred over follow-up periods of 3-61 months. Our technique was shown to be both feasible and safe for the removal of left atrial myxoma.
