Cryoablation for Atrial Fibrillation Using POLARx

This research article presents findings from a multicentre study comparing the safety, efficacy, and procedural metrics of POLARx and Arctic Front Advance in cryoablation for atrial fibrillation. Results indicate that POLARx is a safe and effective method for achieving pulmonary vein isolation (PVI), with procedural success rates exceeding 99% and a major complication rate of less than 1%. The study highlights the importance of modified cryoablation targets when using POLARx.
