Heart Bypass Surgery (CABG): an overview

Coronary artery bypass grafting (CABG) also known as heart bypass surgery is a surgical procedure performed to improve the poor blood supply of the blood vessels to the heart. Poor blood flow occurs when the arteries supplying blood to heart tissues, called coronary arteries are blocked or narrowed. A build-up of cholesterol plaque or fatty deposits within the walls of the arteries causes coronary arteries disease (CAD). CABG procedure lowers the risk of serious complications for those who have obstructive coronary artery disease.

CABG uses healthy blood vessels or grafts from another part of your body and creates a new route by connecting them to blood vessels above and below the blocked artery, bypassing the narrowed or blocked coronary arteries. Blood bypasses the blockage and starts flowing through the new connected healthy vessels. The new vessel is generally taken from the chest, arm, or leg.

Types of heart bypass surgery: -

Conventional heart Bypass surgery: - This is a conventional method of doing heart bypass surgery. Its results are very promising such as-

  • • Reduced chest pain and shortness of breath

This surgery is performed to gain access to the heart by making an incision in the middle of the chest. The heart is beating during the procedure. It is also known as off-pump CABG surgery.

In this surgery, the heart surgeon will make a 3 inch surgical cut on the left part of your chest between your ribs to reach your heart. Muscles in this area are pushed apart. The surgeon then finds and puts together an artery in your chest wall (inner mammary artery) to connect to your coronary artery that is blocked.
