The Clinical Utility of 3D Electroanatomical Mapping for Atrial Fibrillation Ablation by Pulsed Field Ablation.

ABSTRACT:

Background

Pulsed Field Ablation (PFA) is a tissue-selective ablation energy source that has been introduced recently for atrial fibrillation (AF) ablation. Data on the use of 3D electroanatomic mapping (EAM) is limited in AF ablation by PFA with many centers electing to omit it.

Objective

This study sought to investigate the utility of high-density 3D EAM using PFA for AF ablation.

Methods

Seventy-four patients with symptomatic AF underwent PFA-based pulmonary vein isolation (PVI). Additional ablation, including left atrial posterior wall (LAPW) and mitral-isthmus (MI) ablation was performed in a subset of patients. The primary efficacy endpoint was freedom from atrial arrhythmia at 12 months. The primary safety endpoint was freedom from a composite of serious proced
