Key result
Radiofrequency catheter ablation successfully eliminated recurrent ventricular tachycardia in a 13-year-old boy post-tetralogy of Fallot repair, with no recurrence over 13 months.
Why the study?
Does radiofrequency catheter ablation prevent recurrence of ventricular tachycardia in a pediatric patient following surgical correction of tetralogy of Fallot?

Does radiofrequency catheter ablation prevent recurrence of ventricular tachycardia in a pediatric patient following surgical correction of tetralogy of Fallot?
Radiofrequency catheter ablation can successfully treat refractory left ventricular tachycardia in pediatric patients following surgical correction of tetralogy of Fallot.
Hypothesis-generating for ablation in post-TOF pediatric VT; larger prospective studies needed before wider adoption.
A 13-year-old boy had recurrent ventricular tachycardia following surgical correction of tetralogy of Fallot. Pharmacological management with multiple antiarrhythmic drugs failed, and the patient underwent electrophysiological evaluation. A reentrant tachycardia involving a slowly conducting region in the left ventricular outflow tract was demonstrated. We performed radiofrequency catheter ablation after identifying the essential components of the reentrant circuit. The ventricular tachycardia could no longer be induced and did not recur spontaneously during a 13-month follow-up.

Fukuhara et al. (2000) conducted a case report in Recurrent ventricular tachycardia following surgical correction of tetralogy of Fallot (n=1). Radiofrequency catheter ablation was evaluated on Inducibility and spontaneous recurrence of ventricular tachycardia. Radiofrequency catheter ablation successfully eliminated recurrent ventricular tachycardia in a 13-year-old boy post-tetralogy of Fallot repair, with no recurrence over 13 months.
