Coronary Artery Bypass Grafting (CABG)

Coronary artery bypass grafting (CABG) or Heart Bypass is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD).
CHD is a disease in which high cholesterol levels would lead to formation of a waxy substance called plaque inside the coronary arteries. Hardened plaque narrows the coronary arteries and reduces the flow of oxygen-rich blood to the heart. This can cause chest pain or discomfort called Angina.
A secondary Bypass surgery is called a Redo Bypass Surgery. Redo Bypass is a relatively difficult procedure and requires extensive experience by the heart surgeon. A Redo-CABG is required in cases where the Coronary arteries narrow down again due to existing CHD.
During CABG, a healthy artery or vein from the body is connected, or grafted, to the blocked coronary artery. The grafted artery or vein bypasses the blocked portion of the coronary artery, creating a new path for oxygen-rich blood to flow to the heart muscle.
- Improving your quality of life and reducing angina and other CHD symptoms
- Allowing you to resume a more active lifestyle
- Improving the pumping action of your heart if it has been damaged by a heart attack
- Lowering the risk of a heart attack (in some patients, such as those who have diabetes)
- Improving your chance of survival
