Acquired pulmonary vein stenosis: one problem, two mechanisms.
Until the last decade, acquired pulmonary vein (PV) stenosis in the adult population was a rare finding, caused by neoplasm or inflammatory conditions such as sarcoidosis or fibrosing mediastinitis. With the increased use of catheter-based ablation for the treatment of atrial fibrillation, PV stenosis is increasingly recognized as a complication of this procedure. Additionally, PV stenosis has been described as a rare complication of cardiac surgery. This report describes two cases of PV stenosis, one acquired as a result of multiple left atrial ablation procedures and the other after surgical cannulation of the right upper PV.
