Types of Coronary Artery Bypass Grafting

There are several types of coronary artery bypass grafting (CABG). Your doctor will recommend the best option for you based on your needs.

Traditional Coronary Artery Bypass Grafting

Traditional CABG is used when at least one major artery needs to be bypassed. During the surgery, the chest bone is opened to access the heart.

Medicines are given to stop the heart; a heart-lung bypass machine keeps blood and oxygen moving throughout the body during surgery. This allows the surgeon to operate on a still heart.

After surgery, blood flow to the heart is restored. Usually, the heart starts beating again on its own. Sometimes mild electric shocks are used to restart the heart.

Off-Pump Coronary Artery Bypass Grafting

This type of CABG is similar to traditional CABG because the chest bone is opened to access the heart. However, the heart isn't stopped, and a heart-lung bypass machine isn't used. Off-pump CABG sometimes is called beating heart bypass grafting.

Minimally Invasive Direct Coronary Artery Bypass Grafting

This type of surgery differs from traditional CABG because the chest bone isn't opened to reach the heart. Instead, several small cuts are made on the left side of the chest between the ribs. This type of surgery mainly is used to bypass blood vessels at the front of the heart.

Minimally invasive bypass grafting is a fairly new procedure. It isn't right for everyone, especially if more than one or two coronary arteries need to be bypassed.
