Migration of an Amplatzer Septal Occluder Device for Closure of Atrial Septal Defect into the Ascending Aorta With Formation of an Aorta-to-Right Atrial Fistula

The percutaneous closure of atrial septal defects is increasingly used. Serious complications of the procedure, such as cardiac perforation and tamponade, are rare and usually occur <72 hours after device placement. The investigators report the late development of the erosion of an Amplatzer septal occluder into the ascending aorta with associated aortic–to–right atrial fistula formation.
