Migration of Amplatzer Septal Occluder to the Deep Aortic Arch in a Patient With Multiple Anatomic Anomalies.

Abstract

Atrial septal defect closure using the Amplatzer septal occluder (AGA Medical Corp, Golden Valley, MN) device is an established treatment option with excellent clinical outcome. However, several structural characteristics have been reported to be prognostic factors for failure of catheter interventional treatment. We report successful surgical removal of an Amplatzer septal occluder that had become dislocated and had migrated into the deep aortic arch. Compatible with previous reports, the patient presented with an atrial septal defect complicated by multiple anatomic deformities that were considered to be a contraindication for interventional treatment. Detailed structural assessment of the atrial septal defect is mandatory for successful treatment using the Amplatzer septal occluder.
