Safety and Efficacy of Persistent Atrial Fibrillation Ablation With a Cryoballoon Technology

Safety and Efficacy of Persistent Atrial Fibrillation Ablation With a Cryoballoon Technology

The goal of this retrospective observational study is to learn about the safety and efficacy of cryoballoon catheter ablation in 80 patients with persistent atrial fibrillation using the PolarX (Boston scientific) cryoablation technology. The main question it aims to answer is if it is safe and effective.

Inclusion Criteria:

• persistent atrial fibrillation patients undergoing first atrial fibrillation ablation procedure with PolarX cryoballoon

Exclusion Criteria:

• previous atrial fibrillation ablation or cardiac surgery,
• paroxysmal atrial fibrillation,
• congenital heart disease,
• non-treated coronary artery disease,
• intracavitary thrombus,
• significant valvular disease,
• contraindications to general anesthesia.
