| Popis: | The purpose of this study was to evaluate long-term safety and efficacy of catheter ablation of accessory atrioventricular pathways (AP) in a pediatric cohort.Radiofrequency catheter ablation of accessory AP is the recommended treatment for patients with atrioventricular re-entrant tachycardia. Data on long-term results ≥1 year after AP ablation in pediatric patients is sparse.A total of 296 patients 18 years of age who had undergone radiofrequency-AP ablation between October 2002 and June 2015 were included into the study. Follow-up was1 year in all patients. Median age at ablation had been 11.6 years, and median follow-up was 5.6 years. Recurrence of AP conduction after ablation was defined as documentation of pre-excitation, supraventricular tachycardia attributable to AP, or proof of AP conduction during repeat electrophysiological study.AP ablation succeeded in 268 of 296 individuals (91%). After successful ablation, recurrence of AP conduction was observed in 29 of 268 individuals (10.8%). Of those 29, 23 (79%) had AP recurrence within the first year after ablation, whereas 13 (45%) had recurrence of AP conduction already within the first month. Six patients had late recurrence of AP conduction1 year post-ablation. Procedural success and freedom from AP conduction after a single ablation procedure was 86% at 1 month, 83% at 1 year, and 81% at 5 years after ablation.After radiofrequency ablation of AP in children, recurrence of AP conduction occurred in 23 subjects (8% of the study cohort) within the first year after ablation. Late recurrences1 year after ablation were noticed in 6 children (2% of the study group), highlighting the need for longer follow-up1 year. Results of the present study on late AP recurrence should be taken into account whenever families are counselled for pediatric AP ablation. |
