Radiofrequency ablation vs. cryoablation for pediatric atrioventricular nodal reentrant tachycardia in the era of three-dimensional electroanatomical mapping.

ABSTRACT:

Background

Cryoablation for pediatric atrioventricular nodal reentry tachycardia (AVNRT) is favored for reducing conduction system injury compared to radiofrequency (RF) ablation. The safety advantage of cryoablation over RF ablation primarily results from studies conducted without a three-dimensional electroanatomical mapping (3D EAM) system. Currently, 3D EAM systems offer precise and efficient guidance, improving safety and outcomes. This study compares RF ablation and cryoablation using a 3D EAM system for pediatric AVNRT treatment.

Methods

A retrospective study enrolled consecutive pediatric patients with AVNRT who underwent RF ablation (RF group) or cryoablation (Cryo group) guided by a 3D EAM system at multiple centers from July 2018 to January 2024.
