Per-operative biophysicals settings and non-fluoroscopic assessment methods of pulmonary vein occlusion during cryoballoon ablation of atrial fibrillation: comparison between two systems
Introduction: Cryoballoon ablation is safe and secure for pulmonary vein isolation (PVI) in atrial fibrillation (AF). A novel system POLARx (Px), similar to Arctic Front Advance (AFA) has recently been marketed. We compared per-operative settings and non-fluoroscopic methods to evaluate pulmonary ve...
