The most common type of heart surgery for adults is coronary artery bypass grafting (CABG). During CABG, a healthy artery or vein from the body is connected, or grafted, to a blocked coronary (heart) artery. The grafted artery or vein bypasses (that is, goes around) the blocked portion of the coronary artery. This creates a new path for oxygen-rich blood to flow to the heart muscle. CABG can relieve chest pain and may lower your risk of having a heart attack.
Doctors also use heart surgery to: Repair or replace heart valves, which control blood flow through the heart Repair abnormal or damaged structures in the heart Implant medical devices that help control the heartbeat or support heart function and blood flow Replace a damaged heart with a healthy heart from a donor.
