Coronary angioplasty. Coloured 3-D computed tomography (CT) scan of a stent (orange), placed in the heart of sixty year old patient with heart disease. The left coronary artery (pink) is on the top of the heart, and it supplies the heart with oxygenated blood. The left hand branch is the anterior interventricular artery, which had become narrowed. A stent, or wire mesh tube, has been inserted into the artery to hold it open. Stenosis, or narrowing, of arteries leads to reduced blood flow to the areas served by the artery, if the artery becomes completely blocked these areas die, causing myocardial infarction, or heart attack.
