Transcatheter radiofrequency ablation for pulmonary vein isolation can cause transient right phrenic nerve injury, highlighting the need for careful preventive measures.
Heightened phrenic nerve monitoring during PVI may be warranted; this case leaves open optimal preventive strategies.
This report describes a case of transient paresis of the right diaphragm following the transcatheter radiofrequency ablation for the electrical disconnection of pulmonary veins, which recovered completely during the observational period in a 61-year-old woman with paroxysmal atrial fibrillation. For electrical disconnection of pulmonary veins, careful preventive measures for phrenic nerve damage are required.
