Long Term outcomes of percutaneous atrial fibrillation ablation in patients with continuous monitoring

Introduction: There is limited data using continuous monitoring to assess outcomes of atrial fibrillation (AF) ablation. This study assessed long‐term outcomes of AF ablation in patients with implantable cardiac devices. Methods: 207 patients (mean age 68.1 ± 9.5, 50.3% men) undergoing ablation for symptomatic AF were followed up for a mean period of 924.5 ± 636.7 days. Techniques included The Pulmonary Vein Ablation Catheter (PVAC) (59.4%), cryoablation (17.4%), point by point (14.0%) and The Novel Irrigated Multipolar Radiofrequency Ablation Catheter (nMARQ) (9.2%). Results: 130 (62.8%) patients had paroxysmal AF (PAF) and 77 (37.2%) persistent AF. First ablation and repeat ablation reduced AF burden significantly (relative risk 0.91, [95% CI 0.89 to 0.94]; P
