The term that you usually hear about coronary bypass surgery is CABG, which is the acronym for coronary artery bypass graft.
And what that refers to is basically on the heart there is a big blood pipe where the oxygenated blood or the red blood comes out the heart goes to your brain and your arm. And there’s a valve that prevents once the blood comes out to go back into the heart. Just above that valve there’s two main arteries, conduits, that bring that red blood that is rich in oxygen and food to the heart muscle itself.
As you get older those arteries and the one on your body get hardened, and with time narrowing happens. Sometimes it happens faster depending on some risk factors which we can talk about but when the narrowing is enough a few things can happen.
The narrowing or the plaque can crack and then clot and then you have an acute sensations of the blood flow to the heart, that’s when you have a heart attack. Or, the decrease can be small enough that whenever you try to do exercise your heart is suffering and then you get the chest pain or the angina.
And in some people those things happen and they don’t feel it, typically diabetic patients
And there’s other ways, tests we can do to show that the heart is suffering although they can’t feel it so all those can be indications to do something about the blockage.
And there’s two things we can do, one is a catheter-based intervention with the blood and the other one is the CABG or the coronary artery bypass. The coronary artery bypass typically doesn’t deal with the blockage, it bypasses it. So you’re rerouting blood from a site where blood flows properly into the main blood pipe. Or another area of the body and you go and drop that flow beyond the blockage.
And we will use a conduit and the conduit will be typically a vein from your leg or an artery from your arm or an artery from inside your chest. And then we will go and reconnect that artery into that area that we just opened just beyond a bypass.
If you think that you do have angina and coronary artery disease you may be in the need in a coronary artery bypass surgery, the first step is for you to contact your family physicians and get the process initiated.
