Surgical removal of left atrial myxoma through mini sternotomy and the superior transseptal approach.

A 32-year-old man admitted for treatment of a left atrial myxoma showed a 76 x 25 mm tumor in the left atrium originating in the interatrial septum upon echocardiography. The myxoma was surgically removed using a mini sternotomy and the superior transseptal approach. The hospital course was unremarkable. In the 2 years since operation, the patient has remained asymptomatic and tumor-free. The superior transseptal approach is thus useful in surgical removal of left atrial myxoma because it can be excised with minimum manipulation despite the mini sternotomy and small skin incision.
