Does pulsed-field ablation or cryoballoon ablation improve 1-year outcomes compared to radiofrequency ablation in patients with persistent atrial fibrillation undergoing first pulmonary vein isolation?
Pulsed-field and cryoballoon ablation may offer better 1-year outcomes than radiofrequency ablation for first-time pulmonary vein isolation in persistent atrial fibrillation.
In patients with persistent AF undergoing first PVI, 1-year confounder-adjusted outcomes are better with PFA and CBA than with RFA.
Kueffer et al. (2024) studied this question.
