Coronary Artery Bypass Surgery (CABG)

A coronary artery bypass graft (CABG) is a surgical procedure used to treat coronary heart disease. It diverts blood around narrowed or clogged parts of the major arteries to improve blood flow and oxygen supply to the heart. The bypass restores blood flow to the heart which, in turn, restores function, and viability, and relieves anginal symptoms.

How and why is it done?

Coronary artery bypass graft surgery usually lasts 3 to 6 hours. But it may take longer depending on how many blood vessels are being attached. Blood vessels can be taken from your leg, inside your chest, or your arm. CABG is generally recommended when there are high-grade blockages in any of the major coronary arteries and/or percutaneous coronary intervention (PCI) has failed to clear the blockages. 

CABG is also performed as minimally invasive surgery. Being an important major surgical procedure, this helps prevent major morbidity in a patient’s life by relieving anginal symptoms and improving quality of life.

What to expect before coronary artery bypass grafting?

Your doctor might order a number of tests before your CABG procedure. These may include blood tests, EKG, echocardiogram, chest X-ray, cardiac catheterization, and angiography.

You will receive detailed instructions from your doctor on how to prepare for CABG surgery. Instructions will include information on what you can eat or drink, what medicines you can take, and what activities to stop (ex: smoking). Most patients are admitted to the hospital on the same day as the surgery.
