Safety of pulsed field ablation in more than 17,000 patients with atrial fibrillation in the MANIFEST-17K study

Nat MedPublished

  • Multicentre retrospective registry study
  • post-approval

Authors' conclusion

Taken together, these data indicate that PFA demonstrates a favorable safety profile by avoiding much of the collateral damage seen with conventional thermal ablation.
