Case ReportsPulmonary vein stenosis complicating catheter ablation of focal atrial fibrillation.
A recently described focal origin of atrial fibrillation, mainly inside pulmonary veins, is creating new perspectives for radiofrequency catheter ablation. However, pulmonary venous stenosis may occur with uncertain clinical consequences. This report describes a veno-occlusive syndrome secondary to left pulmonary vein stenosis after radiofrequency catheter ablation. ⋯ Multiple radiofrequency pulses applied inside the pulmonary veins ostia can induce severe pulmonary venous stenosis and veno-occlusive pulmonary syndrome.
