Coronary Angioplasty is a medical procedure used to treat coronary heart disease. During coronary angioplasty, a small balloon is inflated inside one or more of your coronary arteries to open up an area of your arteries.
The term "angioplasty" means using a balloon to stretch open a narrowed or blocked artery. However, most modern angioplasty procedures also involve inserting a short wire-mesh tube, called a stent, into the artery during the procedure. The stent is left in place permanently to allow blood to flow more freely.
