Repair of iatrogenic pulmonary vein occlusion with a vascularized atrial flap.

Pulmonary vein obstruction is a rare condition, most commonly reported following pulmonary vein catheter ablation for atrial arrhythmia. This novel technique for treatment of pulmonary venous obstruction has the advantage of utilizing an autologous vascularized flap with intact endothelium for reconstruction of the pulmonary vein and to prevent restenosis.
