Transcatheter closure of aortic sinus to left atrial fistula caused by erosion of Amplatzer septal occluder

Abstract

One year after Amplatzer device closure of an atrial septal defect, an aortic to left atrial fistula was diagnosed in a patient who developed a new onset murmur with no other symptoms. The fistula was closed with a 4-mm Amplatzer Septal Occluder during a transcatheter procedure, avoiding the need for cardiac surgical repair.
