Overview of Coronary Artery Bypass Graft

Coronary Artery Bypass Graft or CABG

Coronary Artery Bypass Graft or CABG (pronounced as "cabbage") is a cardiac procedure performed to reroute or "bypass" blood around clogged arteries to improve blood flow and oxygen to the heart. Coronary artery bypass graft is also commonly known as cardiac bypass surgery, bypass surgery, heart bypass surgery, heart bypass, cardiac bypass or simply bypass.

Depending on the number of coronary arteries bypassed in the procedure, the surgery may be termed single bypass, double bypass (CABG-2x), triple bypass (CABG-3x), quadruple bypass (CABG-4x) and quintuple bypass (CABG-5x).


Indications for CABG

The arteries that bring blood to the heart muscle (coronary arteries) can become clogged by plaque (a buildup of fat, cholesterol and other substances). This can slow or stop blood flow through the heart's blood vessels, leading to chest pain or a heart attack. Increasing blood flow to the heart muscle can relieve chest pain and reduce the risk of heart attack. Therefore, this surgery is done to improve blood flow and oxygen to the heart.

CABG is the preferred treatment for:
•  Disease of the left main coronary artery (LMCA)
•  Disease of all three coronary vessels (LAD, LCX and RCA)
•  Diffuse disease not amendable to treatment with a PCI
•  Other high-risk patients such as those with severe ventricular dysfunction (i.e. low ejection fraction), or diabetes mellitus.


How is the surgery performed?

CABG surgery is usually performed with the heart stopped, necessitating the usage of cardiopulmonary bypass. This is called "on-pump" surgery. In the case of "off-pump" surgery, the operation is performed on a beating heart.

Arteries or veins from elsewhere in the patient's body are grafted to the coronary arteries to bypass the clogged arteries. One end of each graft is sewn onto the coronary arteries beyond the blockages and the other end is attached to the aorta (the largest artery in the body carrying oxygen to all parts of the body).

Recent developments have allowed to carry out this surgery using the minimally invasive approach .


CABG treatment abroad

A cardiac bypass surgery is a major heart surgery. And is therefore, tagged expensively in the United States. This has led many uninsured and underinsured to explore more affordable alternatives overseas.

India, for example, is a well-known and well-regarded destination for cardiac treatments. Some Indian hospitals specializing in treating foreign patients have obtained international accreditations like JCI to lure foreigners looking for low cost high quality heart care.

A bypass surgery costing over $100,000 in the US without health insurance can be had for as little as $10,000 in India with surgery cost, hospital fees, doctor fees, and air travel included. For more information about this, check out medical tourism for heart surgery .
