Wall Thickness-Guided vs. Voltage-Guided Pulmonary Vein Isolation for Atrial Fibrillation.

ABSTRACT:

Background

The efficacy and safety of tailored pulmonary vein isolation (PVI) guided by either left atrial wall thickness (LAWT) or bipolar voltage remain unclear.

Objective

The aim of this prospective study was to evaluate the efficacy and safety of each ablation strategy.

Methods

We conducted a prospective analysis of 97 patients with non-valvular atrial fibrillation (AF) who underwent an initial RF catheter ablation procedure known as an extensive encircling PVI. Fifty patients underwent PVI using a wall thickness (WT)-guided approach using ADAS 3D software and 47 patients using a voltage-guided approach. In each strategy, high-power short-duration (HPSD) ablation was applied to regions with increased LAWT or elevated bipolar voltage, respectively, while very high-
