Key Points

To describe a case of persistent phrenic nerve palsy following cardiac pulsed field ablation and evaluate mechanisms and strategies for prevention.
Assessed a patient who underwent pulsed field ablation using the PulseSelect system and developed persistent phrenic nerve palsy.
Tracked phrenic nerve function over an approximate 6-month recovery period.
Analyzed procedural factors, including repeated energy deliveries and spatial catheter distribution around the right superior pulmonary vein.
Recovery of phrenic nerve function occurred approximately 6 months after the ablation procedure.
Repeated pulse deliveries and catheter clustering near the right superior pulmonary vein were identified as potential mechanisms for persistent nerve injury.

Implication

Supports monitoring for delayed recovery after PFA-related phrenic nerve palsy; hypothesis-generating for energy optimization near pulmonary veins.

Abstract

Persistent phrenic nerve palsy is a rare but possible complication of pulsed field ablation. We report recovery of phrenic nerve function approximately 6 months after PulseSelect ablation and discuss potential mechanisms and preventive strategies, including the effects of repeated applications and their spatial distribution around the right superior pulmonary vein.
