Real‐world trends in atrial fibrillation ablation indicate increasing durability of pulmonary vein isolation at repeat ablation

Durable electrical isolation of pulmonary veins (PVs) is associated with better outcomes after atrial fibrillation (AF) ablation, but previous studies of AF recurrence have reported high rates of reconnection despite successful acute isolation. This study aims to quantify historical trends in the durability of PV isolation (PVI) as radiofrequency (RF) ablation catheters, additional ablation technologies, and associated workflows have evolved.
