Overview

Preclinical evaluation reveals comparable safety and efficacy of nanosecond and microsecond pulsed field ablation for pulmonary vein isolation, indicating a potential for reduced muscle contractions.

Key Points

  • nsPFA demonstrated comparable safety and efficacy to μsPFA in 18 swine ablation procedures.
  • Both protocols achieved effective pulmonary vein isolation with consistent lesion creation.
  • nsPFA resulted in significantly lower muscle contractions compared to μsPFA.
  • These findings suggest nsPFA may lower anesthesia requirements for atrial fibrillation ablation.
