Implication
Supports accessory pathway ablation in pediatric SVT; leaves open randomized confirmation of long-term safety.
Structured PICO
Does radiofrequency catheter ablation safely and effectively treat symptomatic supraventricular tachycardia mediated by accessory pathways in children?
P
Population
53 children and young adolescents <16 years of age (mean 9.3±4.1 years) referred for treatment of symptomatic supraventricular tachycardia mediated by accessory pathways (30 with Wolff-Parkinson-White syndrome, 23 with retrograde-only accessory pathway).
I
Intervention
Catheter ablation of accessory atrioventricular pathway using 500 kHz radiofrequency current (including a solitary catheter technique in 20 children).
O
Outcome
Successful ablation of accessory connections and freedom from arrhythmia-related symptoms.
Radiofrequency catheter ablation is a highly effective and safe first-line therapy for children with symptomatic SVT mediated by accessory pathways, achieving a 96% success rate.
