Key result
RFA successfully resolves refractory VT as a bailout in an 11-month-old following surgical VSD closure.
Why the study?
Ventricular tachycardia is a major cause of postoperative morbidity and mortality in congenital heart disease, but management options when refractory to medical therapy and cardioversion remain challenging.
Case Report (n=1)
Radiofrequency ablation can be a viable bailout strategy for refractory postoperative ventricular tachycardia storm in pediatric patients.
RFA may offer rescue option for refractory postoperative VT in infants; hypothesis-generating and requires prospective validation before broader use.
Arrhythmia is known complication in postoperative period of congenital heart disease among which ventricular tachycardia is one of the major causes of morbidity and mortality. Here we present an unique case of eleven month old baby managed by radiofrequency ablation for refractory ventricular tachycardia in postoperative VSD closure in view of doubly committed VSD with outlet extension due to refractory hypotension and non response to medical therapy and cardioversion. Although VT is mostly managed by medical treatment conservatively in postoperative period, this patient didn’t respond to either medical treatment or cardioversion requiring RFA as bailout strategy. Radiofrequency ablation can be adopted as one of the bailout strategy for the postoperative VT storm even in pediatric population.

Saha et al. (2026) conducted a case report in Refractory ventricular tachycardia following surgical closure of ventricular septal defect (n=1). Radiofrequency ablation was evaluated on Management of refractory ventricular tachycardia. Radiofrequency ablation was successfully used as a bailout strategy for refractory ventricular tachycardia in an 11-month-old baby following surgical closure of a ventricular septal defect.
