Amplatzer Septal Occluder Associated With Late Pulmonary Venous Obstruction Requiring Surgical Removal With Acquired Aorta to Left Atrial Fistula

Abstract

The Amplatzer septal occluder is currently the preferred device for the transcatheter closure of secundum atrial septal defects. Multiple studies have shown that device complications with the Amplatzer occluder are rare and often acute in presentation. The investigators describe the first reported case of late obstruction of the right pulmonary veins with an Amplatzer septal occluder and, in the same patient, an unusual intraoperative finding of a noncoronary aortic sinus to left atrium fistula after device removal.
