Key result
Fixed-loop pulsed field ablation achieves first-pass pulmonary vein isolation in ~51% of patients.
Why the study?
The value of electroanatomic mapping within single-shot pulsed field ablation workflows for atrial fibrillation is unclear, and dedicated high-density data for the fixed-loop catheter are scarce.
Cohort (n=100)

High-density mapping reveals that incomplete pulmonary vein isolation and unintended posterior wall ablation are common acutely after fixed-loop pulsed field ablation, suggesting a potential role for routine mapping to optimize procedural success.

Wang et al. (2026) conducted a cohort in Atrial fibrillation (n=100). Pulsed field ablation with fixed-loop catheter was evaluated on First-pass isolation of all veins on the initial remap. Pulsed field ablation with a fixed-loop catheter achieved first-pass pulmonary vein isolation in 51% of patients, with unintended posterior wall or roof ablation occurring in 30%.
