  • consecutive patients
  • real-world cohort

Authors' conclusion

In this real-world cohort, PFA-guided LAPWI was safe for the esophagus, with no thermal injury observed in post-procedural endoscopy.

Study context

Population
AF patients undergoing pulsed field ablation (PFA)-guided left atrial posterior wall isolation (LAPWI) with post-procedural esophagogastroduodenoscopy (EGD)94% persistent AF
Participants
106 patients
Outcome
Esophageal safety (thermal, ablation-related esophageal lesions on EGD)
Follow-up
The day after PFA

Main finding
