Complete atrio-ventricular heart block, a not to be forgotten complication in transcatheter closure of perimembranous ventricular septal defect - a case report and review of literature.

Device occlusion of perimembranous ventricular septal defect is gaining popularity with the emergence of newer, softer occluders and improved technical know-how. We report a 26-year-old lady with a moderate size perimembranous ventricular septal defect who had a new onset of bundle branch block shortly after device closure. The patient subsequently developed a complete atrio-ventricular heart block.
