Coronary Bypass Surgery to Bypass the Clogged Arteries

Coronary Bypass is also called Coronary Artery Bypass Grafting (CABG) or Heart Bypass is a surgical procedure performed in patients with severe coronary artery disease.

This procedure is usually appropriate for people who have a blocked left main coronary artery, those with disease in many vessels, and poor function of the left ventricle, and with people with debilitating angina pains.

In this procedure the blood flow to the heart muscle is rerouted. Veins or arteries from elsewhere in the body either from the leg, or from the aorta itself are used as a bypass tube to reroute the blood flow.

One end of the new vessel is connected to the aorta, near where the original artery originated, and the other end is connected to the coronary arteries, further down from where the artery was blocked.

By rerouting the artery the blood, can then reach the heart muscle supplying it with the necessary oxygen it needs to pump efficiently.

The Coronary Bypass Procedure

The coronary bypass procedure is done by making an incision in the midline of the chest through the breast bone. The heart is cooled down and chemicals slow down the metabolism of the heart reducing its need for oxygen.

A heart lung machine bypass machine, replaces the function of the heart and the lungs temporarily. The machine takes blood that is returning from the body through the right atrium and diverts it into the machine that oxygenates the blood. It then pumps the blood into the aorta, where it gets pumped into the rest of the organs in the body, except for the heart and lungs.

An incision is made in the leg or elsewhere where the new vessel is taken from. It is removed and connected to the aorta near where the original artery originated from. At times several incisions have to be made when several different arteries have to be bypassed.

The surgery takes around three to six hours, depending on the amount of arteries that have to be bypassed and rerouted.

Results of the Coronary Bypass Procedure

The procedure is usually successful. Around ninety percent of patients state that their angina symptoms have improved significantly, and they are now able to live a more productive active life.

Forty percent of have had the surgery show signs of new blockages within ten years, and the angina symptoms reoccur. Either they are new blockages on the new arteries, or they are new blockages on the arteries that weren't bypassed. Many times these new blockages that are causing the new angina pains are on arteries that are too small to be bypassed.

The Risks of the Coronary Bypass Procedure

There is around a two percent chance of dying from the procedure. If it is done during an acute heart attack the chances increase to around eight percent.

How Can You Prevent the Need for Open Heart Surgery and a Coronary Bypass Procedure?

You can avoid a coronary bypass surgery by taking the necessary precautions to avoid heart disease in the first place.

This can be done through:

Why wait till it's too late, begin living a healthy active lifestyle now.
