Direct Comparison of Two Commercially Available Pulsed Field Ablation Systems for Atrial Fibrillation; Procedure Characteristics and Acute Outcomes.

ABSTRACT:

Background

There are few comparative studies on the everyday clinical outcomes of commercially available pulsed field ablation (PFA) systems for atrial fibrillation (AF).

Objective

This study evaluates the acute efficacy and safety outcomes of the FARAPULSE™ (pentaspline catheter) and PulseSelect™ (circular catheter) system.

Methods

International, multicenter, registry on patients with paroxysmal or persistent AF, undergoing a first ablation using either PFA system between January 29th, 2024 and September 1st, 2024. Primary endpoints were electrical isolation of ablation targets, procedural characteristics and freedom from major adverse events within 30 days postprocedure.

Results

A total of 402 patients were enrolled at the six participating centers, of whom 5
