 A 64-year-old female presented with exertional dyspnea following catheter ablation for atrial fibrillation. Imaging revealed right diaphragmatic elevation and paradoxical breathing, leading to a diagnosis of right diaphragmatic paralysis. Thoracoscopic diaphragmatic plication was performed because of the severity of symptoms. Post-operatively, the modified Medical Research Council scale improved from Grade 4 to Grade 2, with significant improvement in respiratory function. The respiratory status of the patient remained well during the one-year follow-up. This is a case of a patient with diaphragmatic eventration caused by diaphragmatic nerve palsy due to catheter ablation, for which early surgical treatment was effective. We suggest that early thoracoscopic diaphragmatic plication may be useful, particularly in patients with a history of surgery for contralateral lung cancer and poor respiratory function.
