Background & Aims: Ventricular arrhythmias, including premature ventricular contraction (PVC) and ventricular tachycardia (VT), are commonly observed in pediatric patients. Radiofrequency catheter ablation (RFCA) has come to be recognized as the first-line therapy for ventricular arrhythmias in adult patients. However, indications for the RFCA of pediatric ventricular arrhythmias remain controversial. The aim of this study was to elucidate the outcomes of catheter ablation for pediatric ventricular arrhythmias. Methods: Twenty-nine consecutive pediatric patients (age, 2-15 years; 12 male and 17 female) who underwent RFCA for ventricular arrhythmia at Gunma Prefectural Cardiovascular Center between March 2006 and December 2014 were included in this study. Detailed patient medical histories were reviewed from the medical records provided. Results: The success rate of primary RFCA was 83% (24 of 29), with an overall success rate of 93% (27 of 29) including secondary ablations. No major complications, such as cardiac tamponade or atrioventricular block, were noted. The outcomes observed were comparable to those previously established in adult patients. Conclusions: RFCA for pediatric ventricular arrhythmias exhibited a good success rate and few complications. RFCA could be a viable therapeutic option for pediatric ventricular arrhythmias, even in cases of frequent PVC.
