Coronary Angioplasty

Blockage in a coronary artery

Coronary arteries are the blood vessels that supply oxygen-rich blood to the heart muscle. The coronary arteries can get narrowed or blocked by the buildup of plaque. Plaque is made up of extra cholesterol, calcium, and other substances that float in blood. Over time, plaque can build up on the inside walls of the coronary arteries and block the blood flow. A procedure called angioplasty can open up a blocked artery.
