A heart bypass is a surgical treatment for coronary artery disease. The coronary artery carries blood to the heart muscle, supplying it with needed oxygen and nutrients. When this blood vessel narrows, because of a build up of material along its walls, it becomes more difficult for the heart to stay healthy. One way to treat this condition is with a heart bypass operation. To perform the operation, a surgeon removes a piece of vein from a patient’s leg and attaches it to the heart. One end is sewn to the aorta, and the other end is attached to the coronary artery just past the region that is blocked. This lets oxygenated blood flow directly into the heart, bypassing the blockage.
