title: Reversible complete atrioventricular block after percutaneous ASD device closure in a child <15 kg.
abstract: Transcatheter device closure of atrial septal defect (ASD) in small children less than 15 kg may be associated with increased complications. Complete atrioventricular heart block (CHB) is a rare complication of ASD device closure in such a setting. We report the case of a 2-year-old girl, less than 15 kg, who underwent device closure of ASD with Amplatzer Septal Occluder and subsequently developed CHB 12 h after the procedure which resolved completely with steroid treatment on fifth day. Case report of a similar kind is rarely reported in the literature. Despite adequate postero-inferior margin CHB may still occur in small children as in our case.
