This is a procedure recommended by a physician because fatty deposits have narrowed coronary arteries and cause symptoms such as chest pain and/or heart attack. Angioplasty allows the physician to open narrowed arteries without surgery. A small balloon is inserted using a catheter and then inflated at the area of the fatty deposits. Stent placement is the placing of a small, permanent metal tube in the artery where the fatty deposits were, to help keep it open. A patient can have more than one stent placed. This makes the patient's chest pain go away.
