Coronary Artery Bypass Surgery
Coronary Artery Bypass Surgery provides a pathway for blood to flow around the blocked artery and reach your heart again. It requires the use of either a mammary artery (located
in the chest wall) or a saphenous vein (from the leg) or other vessel to restore the needed circulation to the heart muscle.

View of the Heart
The heart is a muscle that pumps blood to the entire body. It has four chambers, two on the right and two on the left. The two chambers on the right side of the heart receive blood from the body and pump it into the lungs where it picks up oxygen. From the lungs, the blood enters the left side of the heart and is pumped to the body. There are four valves in the heart, which keep the blood flowing in one direction. When a valve does not work the way it should, the heart must work harder to perform its job.
Heart valve surgery may be necessary when one or more of the heart valves does not open or close correctly.
The Coronary Arteries are blood vessels that lie on the surface of the heart and carry blood oxygen to the heart muscle. These arteries start at the aorta and are called the Right and Left Coronary Arteries.
The right coronary artery supplies the right side of the heart. The left coronary artery divides into two main branches that supply the left side of the heart. One branch, the Left Anterior Descending, supplies the front wall of the heart. The second branch, the Circumflex, supplies the back and side walls of the heart. All of the arteries further divide into smaller branches so that the entire heart muscle is supplied with blood, carrying oxygen.
