INTRODUCTION: Recently catheter ablation has been accepted as standard therapy for symptomatic supraventricular tachycardia in children. Nature of childhood and the variability of congenital heart diseases and congenital heart surgery distinguishes pediatric catheter ablation from the adult practice.
OBJECTIVES: The aim of the present study was to summarize a single-center experience of the first 30 consecutive patients regarding the electrophysiological studies and catheter ablations, moreover to report on the national adoption of these interventions for pediatric patients in Hungary.
METHODS: Between April 1996 and September 2004 catheter ablation was offered for 30 children as treatment of their supraventricular tachycardia because of failure of pharmacological therapy or parents preference.
RESULTS: The mean age of the patients was 13.7 years (2.3-18.0 years) and the mean weight was 52.0 kg (12.0-81 kg). Electrophysiology study revealed 33 arrhythmogenic substrates in 30 patients, 30 of those 33 were congenital while 3 were acquired. Catheter ablation was attempted in 27 patients with acute success in 24 cases (89%). Recurrence was observed in 2 patients and the redo ablation was effective in both, although a second recurrence occurred later in one of them. There were no major complications, but two minor ones (pseudoaneurysm of arteria femoralis, transient ventricular ectopy) occurred.
CONCLUSIONS: Catheter ablation is safe and effective in children with congenital heart disease. Our results are comparable with the international data.
