Improvement in respiratory function and exercise tolerance following video-assisted thoracoscopic diaphragm plication for symptomatic iatrogenic persistent diaphragm paralysis after radiofrequency catheter ablation

Hemidiaphragm paralysis, a complication of catheter ablation for atrial fibrillation, can severely affect respiratory function and can lead to paradoxical breathing and dyspnea on exertion. A 75-year-old woman with iatrogenic diaphragm paralysis showed improved symptoms, respiratory function, and exercise tolerance after video-assisted thoracoscopic diaphragm plication.
