Coronary artery bypass surgery

The image shows an illustration of bypass surgery to restore blood flow to the heart muscle by diverting the flow of blood around a section of a blocked artery in the heart. Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to your heart. Surgeons use this technique to treat people who have severe coronary heart disease (CHD). CHD is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries which causes symptoms such as angina.
