Heart Bypass Surgery - What You Need To Know

Heart bypass surgery, or cardiac bypass surgery or coronary heart bypass graft (CABG) is a procedure for replacing damaged arteries in the heart muscles. Blood vessels taken from another area in your body are used to repair the damaged arteries. This is done to restore normal blood flow to an obstructed coronary artery. Coronary arteries transport blood to and from the heart muscle itself.


There are 4 different types of heart bypass surgeries depending on the number of arteries blocked. These are:

Who Needs A Heart Bypass Surgery?

CABG is for people with severe coronary heart disease that could lead to heart attack or threaten life. It might also be used after a heart attack to treat the blocked arteries thatcause it. Heart bypass surgery will usually be recommended by a cardiologist when prescribed medicines or advised lifestyle changes do not work. Severe blockages in the arteries as mentioned above can also lead to a doctor recommending bypass surgery, particularly if your heart's pumping rate turns out to be weak in tests. It will also be recommended if the blockages in your coronary arteries cannot be treated with PCI (percutaneous coronary intervention), commonly known as coronary angioplasty.

How Is The Need For A Cardiac Bypass Surgery Determined?

The team of the cardiologist treating you will determine whether you can undergo bypass surgery. They will decide that based on factors such as:

How Is The Surgery Done?

After a few tests and examinations, the patient is sedated. Then a surgeon will remove a blood vessel, called a graft, from another part of the body, like the chest, leg, or arm. He attaches one end of it to the aorta, a large artery that comes out of the heart. Then, he attaches the other end to an artery below the blockage.The graft creates a new route for blood to travel to the heart. If the patient has multiple blockages, the surgeon may perform one or more bypass procedures during the same surgery as described above. The patient remains asleep the whole time, about 3 to 6 hours on average. After the surgery, they'll wake up in the ICU (intensive care unit) with a mask to help them breathe and hooked to machines to monitor their vitals. They'll stay there for at least 3 to 5 days.
