Abstract

Percutaneous transcatheter atrial septal defect (ASD) closure is a widely used technique that has replaced open-heart surgical closure in many centers. The most common implant is the Amplatzer septal occluder which seems to be a highly effective and safe device. However, there are reports of complications associated with its implantation. We report a 9-year-old boy who presented with complete atrioventricular block after undergoing percutaneous closure of a large secundum ASD with an Amplatzer septal occluder. We treated the patient with oral prednisolone. The patients atrioventricular conduction improved to second-degree Mobitz type 1 block on post-procedure day 24 and first-degree block on day 35. We conclude that patients with Amplatzer septal occluder-induced complete atrioventricular block generally have a good outcome, although it may take several weeks for improvement.
