Phrenic Nerve Injury During Ablation of Atrial Fibrillation: Mechanisms, Clinical Features, Prognosis, and Prevention Methods

Atrial fibrillation ablation procedures have become a focus of research among electrophysiologists, with the aim increasing success rates while minimizing complications. One major concern is phrenic nerve injury (PNI). Despite advancements in strategies, equipment, and monitoring methods, incidence PNI during these remains substantial, particularly cryoballoon ablation, which has reported 3.5%. This review examines recent studies, to provide comprehensive overview mechanisms, clinical features, prognosis, methods for prevention ablation.
