Simple right atrial procedure for chronic atrial fibrillation with atrial septal defect and aortic valvular regurgitation in an elderly patient.

A right atrial separation procedure was performed to eliminate atrial fibrillation (AF) during concomitant repair of an atrial septal defect and aortic valve regurgitation in an elderly patient. This procedure consisted of a Y-shaped incision in the right atrium, followed by cryoablation of the tricuspid annulus and the atrial septum. Only excision of the left atrial auricular appendage was performed in the left atrium. Although this procedure was devised to eliminate chronic AF associated with a solitary atrial septal defect, it was effective to eliminate chronic AF associated with atrial septal defect and aortic valve regurgitation in an elderly patient.
