Background:
Radiofrequency catheter ablation for paroxysmal atrial fibrillation is well established but not drawback free. Pulmonary vein stenosis is one of the complications and usually treated with stenting with the disadvantages of high re-stenosis rate and anticoagulant dependence.
Case presentation:
Herein, we present the case of a 47 year-old lady, who suffered from fever and hemoptysis due to right inferior pulmonary vein occlusion after radiofrequency catheter ablation for paroxysmal atrial fibrillation. Eventually, thoracoscopic right lower lung lobectomy was inevitable with satisfactory result.
Conclusions:
Pulmonary vein stenosis is a major complication after radiofrequency ablation of atrial fibrillation. High suspicion and early detection in patients with pulmonary manifestations are mandatory for salvage the injured lung in early. If delayed, surgical resection of the involved lung, especially through the thoracoscopic approach will eradicate the problem with minimal complication.
