Procedural performance between two cryoballoon systems for ablation of atrial fibrillation depends on pulmonary vein anatomy

ABSTRACT: Abstract

Background

Cryoballoon ablation is a first‐line therapy for atrial fibrillation. We compared the efficacy and safety of two ablation systems and addressed the influence of pulmonary vein (PV) anatomy on performance and outcome.

Methods

We consecutively enrolled 122 patients who were planned for first‐time cryoballoon ablation. Patients were assigned 1:1 for ablation with the POLARx or the Arctic Front Advance Pro (AFAP) system and followed‐up for 12 months. Procedural parameters were recorded during the ablation. Before the procedure, a magnetic resonance angiography (MRA) of the PVs was generated and diameter, area, and shape of each PV ostium were assessed. We applied an evaluated PV anatomical scoring system on our MRA measurement data ranging from 0 (best ana
