Why the study?
Pulmonary vein isolation is fundamental for invasive atrial fibrillation treatment, motivating this report of single-center cryoablation experience and long-term clinical outcomes.
Does cryoablation of the pulmonary veins prevent atrial fibrillation recurrence in symptomatic patients resistant to medical therapy?
Observational (n=106)
No
Does cryoablation of the pulmonary veins prevent atrial fibrillation recurrence in symptomatic patients resistant to medical therapy?
Cryoballoon pulmonary vein isolation provides an 83% long-term freedom from atrial fibrillation in symptomatic patients, with higher success rates in paroxysmal compared to persistent AF.

Küp et al. (2022) conducted an observational in Symptomatic atrial fibrillation (n=106). Cryoballoon ablation (Paroxysmal AF) vs. Cryoballoon ablation (Persistent AF) was evaluated on Atrial fibrillation recurrence (p=0.0032).
