Background —This report describes the complication of pulmonary vein stenosis with resultant severe hypertension that developed in 2 patients after successful catheter ablation chronic atrial fibrillation. Methods and Results —Three months fibrillation, both progressive dyspnea hypertension. Both were found to have all 4 veins near junction left atrium. Balloon dilation stenotic was performed these patients, improvement Conclusions —The is potentially life-threatening, application radiofrequency current within standard technology should be avoided. This can treated balloon dilation, although long-term course unknown.
