OP-126 Cryoballoon Ablation for Pulmonary Vein Isolation in Patients with Persistent Atrial Fibrillation: Medium Term Outcomes of the Index Procedure




Background


Data regarding the freedom from atrial fibrillation (AF) in the follow-up of persistent AF patients is limited. The second-generation cryoballoon has better cooling properties compared to first generation. In this study we aimed to assess the medium term efficacy of second generation cryoballoon in patients with persistent AF.




Methods


113 patients (63± 10 years, 83 male, 73%) patients with symptomatic persistent AF despite ≥1 antiarrhythmic drug(s) who were scheduled for pulmonary vein isolation using cryoballoon were enrolled in this prospective observational study. Follow-up was based on outpatient clinic visits including Holter ECGs. Recurrence was defined as a symptomatic or documented arrhythmia episode of >30 seconds excluding a 3-month blanking period.
