Left Atrial Voltage Attenuation Beyond Ablation Sites After Unipolar Pulsed‐Field Ablation for Atrial Fibrillation

ABSTRACT Introduction Unlike most pulsed‐field ablation (PFA) systems, Affera (Medtronic) delivers unipolar energy between a lattice‐tip catheter and a cutaneous return patch, potentially generating a broader electric field. We hypothesized that this may attenuate voltage beyond...
