Pulmonary vein stenosis requiring lobectomy after radiofrequency catheter ablation for atrial fibrillation.

Pulmonary vein stenosis is one of the potential complications of radiofrequency catheter ablation for atrial fibrillation. This complication is generally treated by transcatheter techniques using balloon angioplasty or stent implantation. We report a case of a 17-year-old boy with acquired left inferior pulmonary vein stenosis following radiofrequency catheter ablation for atrial fibrillation, conditioning recurrent pneumonia. Despite three attempts of vein dilation by means of angioplasty, the stenosis always recurred with worsening of symptoms. A left inferior lobectomy was then performed and after 33 months the patient is well and with no symptoms.
