Percutaneous atrial septal defect (ASD) closure has become an increasingly simplified procedure over the past decade. The device embolization is seen rarely but it can be fatal. Although percutaneous retrieval is feasible, surgical removal might be preferred when the endothelialization status of the device is unknown. We report a comlication of such closure in a 43-year-old woman: embolization of the ASD occluder device into aortic arch 12 months after implantation. We removed the device surgically and closed the ASD.
