Does cryoballoon ablation prevent the occurrence of atrial tachyarrhythmias in patients with persistent atrial fibrillation?
Cryoballoon ablation is a non-inferior alternative to radiofrequency ablation for maintaining sinus rhythm at 1 year in patients with persistent atrial fibrillation.
In this randomized trial, cryoballoon ablation was non-inferior to radiofrequency ablation for the occurrence of atrial tachyarrhythmias at 1 year in patients with persistent atrial fibrillation.
Miyamoto et al. (2025) studied this question.
