description | Background Arrhythmias are one of the reasons for emergency hospitalization among the pediatric population. Radiofrequency ablation is a major advancement in the management of children with cardiac arrhythmias. Objectives Our study was designed to describe the outcomes of catheter ablation in the pediatric population for atrial and ventricular arrhythmias in our center. Methods All patients between two and 18 years of age undergoing radiofrequency ablation after failed medical management for arrhythmias in our institute were included. Age less than two years, no previous medical management, and complex congenital heart disease were excluded. Baseline and electrophysiological characteristics were recorded. The patients were followed up for a clinical or electrocardiographic recurrence of arrhythmia. Results Thirty-six patients were included (mean age 12.8 ± 3.9 years (range 2-18 years), male 56%, average weight 36.39 ± 11.02 kg). The mean follow-up duration was 27.7 ± 15.9 months (range 3-58). Five-point five percent (5.5%) had tachycardiomyopathy. The arrhythmias included (1) atrioventricular nodal re-entrant tachycardia (AVNRT, n=16, 44%), (2) atrioventricular reciprocating tachycardia (AVRT, n=14, 39%), (3) atrial tachycardia (AT, n=2, 5.5%), (4) ventricular premature complexes (VPCs, n=2, 5.5%), (5) atrial flutter (AFL, n=1, 3%), and (6) ventricular tachycardia (VT, n=1, 3%). A transeptal puncture was done in 10 patients (28%). 3D mapping was done in six patients. The mean radiofrequency (RF) pulses were 2.3 ± 1.3. The acute procedural success rate was 100%. The long-term success was 97.2%. One (2.7%) developed recurrence. No major complications were reported. Conclusion Catheter ablation in the pediatric population is a safe procedure and can be done with more feasibility and fewer complications when done in experienced hands. |
