What is the clinical course and what are the risk factors for persistent phrenic nerve palsy after atrial fibrillation ablation?
Persistent phrenic nerve palsy after AF ablation has a favorable prognosis, with most patients recovering and remaining asymptomatic.
After AF ablation, persistent PNP recovers in the majority of patients, and most are free of symptoms. Female patients and patients treated with cryoballoon or thoracoscopic ablation are more prone to develop PNP.
