Key result
Second-generation cryoballoon-based pulmonary vein isolation resulted in a 60.2% single-procedure and a 78.6% multiple-procedure success rate for maintaining stable sinus rhythm after 3 years.
Why the study?
Does pulmonary vein isolation using the 2nd-generation cryoballoon prevent atrial arrhythmia recurrence in patients with paroxysmal or persistent atrial fibrillation?

Does pulmonary vein isolation using the 2nd-generation cryoballoon prevent atrial arrhythmia recurrence in patients with paroxysmal or persistent atrial fibrillation?
Second-generation cryoballoon-based pulmonary vein isolation provides durable long-term (3-year) rhythm control in patients with paroxysmal and persistent atrial fibrillation, with a 78.6% success rate after multiple procedures.
Heeger et al. (2017) conducted a cohort in Paroxysmal and persistent atrial fibrillation (n=100). 2nd-generation cryoballoon-based pulmonary vein isolation was evaluated on Recurrence of any symptomatic and documented atrial arrhythmia >30 s following a blanking period of 3 months. Second-generation cryoballoon-based pulmonary vein isolation resulted in a 60.2% single-procedure and a 78.6% multiple-procedure success rate for maintaining stable sinus rhythm after 3 years.
