Abstract :
Phrenic nerve injury (PNI) is a rare complication of catheter ablation therapy, most commonly observed in cryoablation of the
right side pulmonary veins. We present a case of PNI after radiofrequency catheter ablation that developed acute dyspnea 24 hours
after the intervention. Dyspnea is the main symptom of PNI, so the diagnosis should always be suspected if it appears after any type
of catheter ablation involving the trajectory of the phrenic nerve. There is no specific treatment for PNI. The only maneuver that
has been reported to accelerate the recovery of PNI is early stopping of the ablation therapy.
