ABSTRACT
When dislodged stents remain on the coronary wire, the wire can be snared outside of the body (presnaring), and the snare loop advanced over the wire into the body to retrieve the stent. Presnaring may be a valuable technique to retrieve dislodged coronary stents when the stent remains on the coronary wire, as demonstrated in the 2 patients described.

We present the case of a 66-year-old woman presenting with pulmonary vein stenosis with a large descending thoracic aortic aneurysm. Pulmonary vein stenosis is a rare condition and can be caused by extrinsic compression, as well as by inflammatory diseases, congenital anomalies and related surgical repair, tuberculosis, and pulmonary veno-occlusive disease. With obstruction to pulmonary vein flow, the velocity increases and becomes continuous. The finding of turbulent antegrade flow in the left atrium through the use of transthoracic color flow Doppler and pulsed-Doppler warrants further investigation to evaluate known causes of pulmonary vein stenosis. We believe this is the first reported case of a patient with an aortic aneurysm causing pulmonary vein stenosis.
