Key result
Radiofrequency catheter ablation in pediatric patients achieved a success rate of 92.8% for accessory pathways and 96.3% for AVNRT, with an overall complication rate of 3.8%.

Structured PICO
Does radiofrequency catheter ablation safely and effectively treat arrhythmias in pediatric patients?
P
Population
131 pediatric patients (mean age 12.0 years, 46.6% female) aged ≤15 years with arrhythmias undergoing radiofrequency catheter ablation, followed for a mean of 13.1 months.
E
Exposure
Radiofrequency catheter ablation (RFCA) performed with or without sedation (conscious sedation, deep sedation, or general anesthesia).
O
Outcome
Efficacy (success rate of ablation) and safety (overall complication rate).
Radiofrequency catheter ablation is a highly effective and safe first-line therapy for pediatric patients with arrhythmias, and can often be performed without sedation in children over 10 years old.
Limitations
- Retrospective study design
- Frequency of arrhythmias could be influenced by patient selection
- Radiation time was not recorded in some patients
- 3-dimensional mapping was not available at the beginning of the study
- Retrospective design, meaning frequency of arrhythmias could be influenced by patient selection
- RFCA of AT and VT was performed in selected cases due to technical difficulties
Cite This Study
Joung et al. (2006) conducted a cohort in Arrhythmias (n=131). Radiofrequency catheter ablation was evaluated on Procedural success rate. Radiofrequency catheter ablation in pediatric patients achieved a success rate of 92.8% for accessory pathways and 96.3% for AVNRT, with an overall complication rate of 3.8%.
