Pulmonary Vein and Artery Stenting

This procedure is used to open up a pulmonary vessel that may have narrowed for a variety of reasons. A stent is placed over a tiny deflated balloon and delivered to the narrowed portion of the vessel using a catheter (thin, flexible tube) fed through a vein. Once in place, the balloon is inflated, thereby expanding the stent and anchoring it in place. The balloon and catheter are then withdrawn.
