ABSTRACT
The present study aimed to assess the efficacy and safety of radiofrequency [RF] catheter ablation in treatment of Supraventricular tachycardia [SVT] in children. A total of 60 pediatric patients with clinically documented SVT underwent an electrophysiologic study and RF catheter ablation at Mansoura University Children Hospital. The arrhythmias included alrioventricular reentrant tachycardia [AVRT; n = 45, 75%], atrioventricular nodal reentrant tachycardia [AVNRT; n = 6, 10%], and atrial tachycardia [AT; n = 9, 15%]. The success rate of the RF catheter ablation was 93.3% for AVRT, 66.7% for AVNRT, and 77.8% for AT, respectively. Procedure-related complications were infrequent [7/60, 11.7%], [atrial flutter during RF catheter ablation [4/60, 6.6%]; ventricular fibrillation during RF catheter ablation [1/60,1.6%]; transient complete heart block during anesthesia or during RF catheter ablation [2/60, 3.3%]]. The recurrence rate was 8.3% [5/60] during a follow-up period of 24 months. RF catheter ablation is an effective and safe method to manage children with SVT
