Robotic Resection of Left Atrial Myxoma With Cryoablation of Tumor Stalk

Abstract

The purpose of this report is to demonstrate robotic cryoablation of an atrial myxoma stalk as a method to prevent recurrence and preserve atrial tissue. A 38-year-old female patient was taken to the operating room, and an atrial myxoma abutting the left inferior pulmonary vein was resected robotically. This was followed by cryoablation of the tumor stalk instead of a full-thickness resection to prevent an extensive reconstruction. The operation resulted in the successful resection of an atrial myxoma with minimal length of stay. Follow-up at 3 months has shown no evidence of residual or recurrent tumor. Follow-up at 1 year is planned. Cryoablation of an atrial myxoma stalk, when resection would require complex reconstruction, is a useful tool in the armamentarium of a minimally invasive cardiac surgeon.
