Key result
Steroids reverse early complete AV block following transcatheter ASD closure in a low-weight child.
Why the study?
Complete atrioventricular heart block is a rare but serious complication after transcatheter ASD device closure in small children less than 15 kg, with limited case reports available.

CHB after ASD device closure in a child <15 kg resolved with steroids; leaves open incidence, risk factors, and management in this population.
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.

Rohit et al. (2014) conducted a case report in Atrial septal defect (n=1). Transcatheter ASD device closure (Amplatzer Septal Occluder) was evaluated on Complete atrioventricular heart block (CHB). Transcatheter ASD closure with an Amplatzer Septal Occluder in a 2-year-old (<15 kg) caused complete atrioventricular block at 12 hours that completely resolved with steroids on the fifth day.
