Types of Coronary Artery Bypass Grafting

Traditional Coronary Artery Bypass Grafting

This is the most common type of coronary artery bypass grafting (CABG). It's 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, and a heart-lung machine is used to keep blood and oxygen moving throughout the body during surgery. This allows the surgeon to operate on a still heart. After surgery, the heart is restarted using mild electric shocks.

Off-Pump Coronary Artery Bypass Grafting

This type of CABG is similar to traditional CABG in that the chest bone is opened to access the heart. However, the heart isn't stopped, and a heart-lung machine isn't used. Off-pump CABG is sometimes called beating heart bypass grafting. This type of surgery may reduce complications that can occur when a heart-lung machine is used, and it may speed up recovery time after surgery.

Minimally Invasive Direct Coronary Artery Bypass Grafting

This surgery is similar to off-pump, but instead of a large incision to open the chest bone, several small incisions are made on the left side of the chest between the ribs. This type of surgery is used mainly for bypassing the vessels in front of the heart. It's a fairly new procedure, which is performed less often than the other types. This type of surgery is not for everybody, especially if more than one or two coronary arteries need to be bypassed.
