What is Heart Bypass Surgery?
Heart bypass surgery is a procedure that is done to divert the blood flow in the heart around a narrowed or blocked artery. It is also commonly called coronary bypass surgery or coronary artery bypass graft (CABG).

Narrowed or blocked arteries can cut off blood flow, causing heart attacks or heart attack-like symptoms. Bypass surgery restores blood flow by using blood vessels from other parts of your body to create a detour around blockages. Sometimes this surgery is referred to by the number of blockages that need to be treated. For example, a quadruple bypass refers to four areas that need to be treated.

What happens in Heart Bypass Surgery?

First, your surgeon will harvest a spare vein from the leg or an artery from underneath the sternum or the arm. This vein or artery is called a graft.

Then the surgeon will make an incision in the center of your chest. They’ll also split your breastbone (sternum) down the middle, then spread and lift your rib cage to make it easier to access your heart. Next, the surgeon will take the harvested blood vessel and craft the bypass.

The upper end of the bypass attaches to your aorta, the large artery that carries blood out of your heart and to the rest of your body, just after it exits your heart. The lower end (ending) of the bypass will attach to the blocked artery just beyond the blockage. The graft bypasses the blockage.

Once the bypass is in place, the surgeon can restart your heart (if they stopped it) and get your blood flowing again. They’ll then lower your rib cage back into place and wire it together so it can heal. They’ll then close the incision in your chest with staples and stitches.

What are the risks of Heart Bypass Surgery?

Heart Bypass surgery is considered major surgery, meaning there are potential risks and complications. While most are avoidable or treatable, it’s still important to understand them.

Possible risks include:
Arrhythmias
Bleeding
Infection
Kidney dysfunction
Memory loss or difficulty thinking clearly
Stroke or heart attack

What are the benefits of Heart Bypass Surgery?

The surgery carries many benefits, particularly for those with serious cardiovascular disease. The operation can be life-saving in event of a heart attack or if the patient is at high risk of having one.

For those with angina and shortness of breath from diseased heart arteries, elective coronary bypass surgery is highly effective at eliminating or reducing discomfort. Coronary bypass surgery, along with lifestyle changes after can help restore quality of life.

0.6 -> What is heart bypass surgery? And what happens exactly?

5.7 -> When cholesterol-filled plaque builds up in an artery wall,

9 -> only a small amount of blood gets through.

14.04 -> We are now looking at the heart and the main blood vessels.

17.16 -> Here is a coronary artery, and right here inside that artery is a blockage.

24.06 -> Because of the blockage, the part of the heart nourished

27 -> by that artery is pale from lack of blood.

30.9 -> The solution:

32.76 -> Attach another blood vessel to the blocked artery just beyond the blockage right there.

38.4 -> The surgeon takes a spare vein from the leg or an artery from underneath the sternum or the arm.

44.94 -> This vein or artery is called a graft.

50.28 -> If a leg vein or an arm artery is used as the graft, one end is attached to the body's main

56.22 -> artery, the aorta, and the other end is attached to the blocked artery just beyond the blockage.

64.44 -> The graft bypasses the blockage.

67.38 -> Now the blood is flowing from the aorta, through the bypass graft, and into the artery that was

73.14 -> blocked. Beyond the blockage, blood is flowing again to all parts of the heart.
