A Stent is a tiny wire mesh tube. It props open an artery and is left there permanently. When a Coronary Artery (artery feeding the heart muscle) is narrowed by a build-up of fatty deposits called Plaque, it can reduce Blood flow. If Blood flow is reduced to the heart muscle, chest pain can result. If a clot forms and completely blocks the Blood flow to part of the heart muscle, a Heart failure results. Stents help keep Arteries open and reduce the chance of heart attack. A Stent is inserted into the clogged Artery with a balloon catheter. The Balloon tipped to inflated and the stent expands and locks in place. This hold the Artery open and allows blood to flow more freely. This compresses the Plaque and open the narrowed spot. When opening in the vessel has been widened, balloon is deflated and catheter is withdrawn. This improves blood flow to the heart muscle and relieves symptoms ( usually chest pain). In a over third of patients, who have Angioplasty without a stent, the art
