MODEL RELEASED. Heart surgery. Surgeons performing coronary bypass surgery. The surgeon at left has magnifying lenses on his glasses. The operation involves grafting blood vessels onto the heart in order to bypass blocked or narrowed coronary arteries. These are the arteries that supply oxygen to the heart muscle. The grafted blood vessels are usually taken from the patient's leg. Blocked coronary arteries cause angina pectoris (chest pain) and heart attacks (myocardial infarctions) | |
