Pulsed Field or Conventional Thermal Ablation for Paroxysmal Atrial Fibrillation

Pulsed Field or Conventional Thermal Ablation for Paroxysmal Atrial Fibrillation BACKGROUND: Catheter-based pulmonary vein isolation is an effective treatment for paroxysmal atrial fibrillation. Pulsed field ablation, which delivers microsecond high-voltage electrical fields, may limit damage to tissues outside the myocardium. The efficacy and safety of pulsed field ablation as compared with conventional thermal ablation are not known. METHODS: In this randomized, single-blind, noninferiority t...
