Comparative analysis of anaesthesia modalities in pulmonary vein isolation: insights from a prospective multicentre registry.

Aims: Atrial fibrillation (AF), the most common sustained arrhythmia in adults, is increasing in prevalence globally. Catheter ablation (CA), particularly pulmonary vein isolation (PVI), is a key treatment option. Pulmonary vein isolation can be performed using different energy sources, including cryoballoon ablation (CBA), radiofrequency ablation (RFA), or pulse field ablation.
