This study examined outcomes of patients with atrial fibrillation treated with pulsed field ablation (PFA) and found a notably high incidence of phrenic nerve injury during the procedure. Most injuries were transient, but some persisted beyond the immediate peri-procedural period, raising concerns about long-term safety. The findings highlight the need for refined techniques and monitoring strategies to mitigate phrenic nerve injury risk with PFA. Please join host Michael S. Lloyd, MD, FHRS as he discusses the finding of this study with his guests Andrea M. Russo, MD, FHRS and Birju Rao, MD, Msci in Atlanta at the HRX Live 2025 conference.

Learning Objective:

• Examine outcomes of patients with atrial fibrillation treated with pulsed field ablation (PFA).
