3D Mapping Versus Conventional Ablation in AVNRT
Sponsor: Kafrelsheikh University
Summary
This prospective randomized interventional study compared conventional fluoroscopy-guided slow pathway ablation versus three-dimensional electroanatomical mapping-guided ablation in patients with electrophysiologically confirmed typical atrioventricular nodal re-entrant tachycardia (AVNRT). A total of 108 patients were screened for eligibility, of whom 80 eligible patients were randomized in a 1:1 ratio to either conventional fluoroscopic ablation or 3D mapping-guided ablation. Following post-randomization dropouts, the final analysis included 38 patients in the conventional group and 36 patients in the 3D mapping group. The study evaluated fluoroscopy exposure, procedural efficacy, complete slow pathway elimination, procedural success, complications, and arrhythmia recurrence during follow-up.

Interventions
Conventional Slow Pathway Ablation
Conventional fluoroscopy-guided catheter ablation of the slow AV nodal pathway using anatomical landmarks and intracardiac electrogram criteria within the triangle of Koch.
3D Electroanatomical Mapping-Guided Ablation
Three-dimensional electroanatomical mapping-guided catheter ablation of the slow AV nodal pathway using CARTO or EnSite X systems with voltage and activation mapping guidance.
