Abstract
Radiofrequency (RF) ablation for tachycardia in children poses challenges in view of slender veins and delicate cardiac structures in close proximity. We reviewed hospital records for patients below 18 years,who underwent RF ablation from August, 2001 to February, 2017 at a single hospital. Among 214 patients (134 males, age12.5 (4.6) years), there were 221 tachycardia substrates: accessory pathways in 85 patients (39%), AV nodal re-entrant tachycardia in 79 patients (36%), ventricular tachycardia in 28 patients (13%) and atrial tachycardia in 21 patients (9.6%).The overall success rate of RF ablation was 95% (204/214). Success rate in those younger than 6 years was similar to those in older age groups. There were no major complication. RF ablation below 18 years of age has a high success rates and low complications.
