[Treatment of pulmonary vein stenosis after percutaneous ablation of atrial fibrillation].
This case report describes a patient with persistent atrial fibrillation (AF) submitted to radiofrequency catheter ablation of AF through the pulmonary vein antrum isolation technique, who developed a severe stenosis of the left superior pulmonary vein (LSPV), without presenting any symptoms. The diagnosis of the PV stenosis was made by a routine postprocedure computed tomography scan of the left atrium, and the patient was subsequently submitted to angioplasty with stenting of the LSPV, resulting in the normalization of pulmonary perfusion, as seen by ventilation/perfusion scan made three months after the LSPV angioplasty.
