Implication

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.
