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