Atrial Fibrillation Ablation: Radiofrequency or Cryoablation?

Overview

The study aims to compare 3 techniques routinely used for paroxysmal atrial fibrillation ablation: radiofrequency catheter ablation without contact-force, radiofrequency catheter ablation with contact-force and cryoablation. The hypothesis is the non-inferiority between the 3 techniques in terms of free-from atrial fibrillation survival (primary criteria). It will also compare lenght of procedure, radioscopy time and immediate complications (secondary criteria).
