Does pulmonary vein isolation using the second-generation cryoballoon prevent arrhythmia recurrence in patients with persistent atrial fibrillation?
Pulmonary vein isolation using the second-generation cryoballoon for persistent AF provides a 63.3% mid-term success rate, highlighting the importance of patient selection (e.g., left atrial size) and procedural experience.
Akkaya et al. (2018) conducted a cohort in persistent atrial fibrillation (n=281). Pulmonary vein isolation using the second-generation cryoballoon (CB-Adv) was evaluated on Freedom from AF, atrial flutter, or atrial tachycardia. Pulmonary vein isolation using the second-generation cryoballoon in patients with persistent atrial fibrillation resulted in 63.3% freedom from atrial arrhythmias at a median 33 months follow-up.
