What is a Stent?
A stent is a small, mesh-like device made of metal. When a stent is placed inside a coronary artery, it acts as a support or scaffold, keeping the vessel open. By keeping the vessel open, the stent helps to improve blood flow to the heart muscle and reduce the pain of angina. Stent procedures are usually used along with balloon angioplasty. In fact, about 80% of patients who have balloon angioplasty will have a stent placed in as well.
