Beyond the Learning Curve: How Operator Experience Affects Pulsed-Field Ablation Outcomes.

Heart Rhythm
BACKGROUND The learning curve for pulmonary vein isolation (PVI) using "single-shot" pulsed-field ablation (PFA) is thought to be short. 3D electro-anatomical mapping (3D-EAM) might provide adjunctive information to shorten the learning curve and improve
