Non-fluoroscopic vs. fluoroscopic radiofrequency catheter ablation for pediatric atrioventricular nodal reentrant tachycardia: a comparative study of procedural characteristics and ablation site.

ABSTRACT:

Background

Non-fluoroscopic cryoablation is considered safe for pediatric atrioventricular nodal reentrant tachycardia (AVNRT), but concerns about prolonged procedures and recurrence persist, requiring continued use of radiofrequency ablation (RFA). Non-fluoroscopic RFA, guided by three-dimensional mapping, offers enhanced precision. This study compares its safety and effectiveness with fluoroscopic RFA in pediatric AVNRT.

Methods

We retrospectively analyzed children undergoing RFA without (X- group) or with (X+ group) fluoroscopy at multiple centers (2011-2024). Patients who received fluoroscopic and three-dimensional mapping guidance were excluded. Baseline characteristics, electrophysiological data, and ablation outcomes were compared.

Results

Among 119 patients (X
