Late complete atriovenous block after percutaneous closure of a perimembranous ventricular septal defect.
Percutaneous closure of a perimembranous ventricular septal defect (VSD) is an alternative to surgical closure. Complications include arrhythmias and in particular early postoperative complete atrioventricular (AV) block. We report the cases of two patients, aged 2.5 and 4 years, treated with an eccentric VSD occluder device whom developed complete AV block 4 and 12 months after the procedure. The first patient experienced syncope, while the second one was completely asymptomatic. Both subjects underwent endocardial ventricular pacemaker implantation.
