A coronary artery bypass graft is surgery to treat coronary artery disease. It allows blood to bypass narrowed or clogged parts of your arteries to improve blood flow to your heart.
CABG does not cure coronary heart disease (CHD) and atherosclerosis. It can ease symptoms, such as chest pain and shortness of breath, improve your heart function and reduce your risk of a heart attack.
During CABG, a healthy artery or vein from another part of your body (usually the chest, leg or arm), known as the graft, is attached to your coronary artery. One end of the graft is placed above the narrowed area or blockage in your artery and the other end below it. Blood then bypasses the blocked or narrowed part of your artery by flowing through your new healthy artery or vein to reach your heart.
You may need more than one graft depending upon the extent of your coronary heart disease and the number of coronary blood vessels that have become narrowed. These are known as a double, triple or quadruple bypass.
CABG is traditionally performed by open-heart surgery where a long cut is made in your chest to access your heart. On-pump coronary bypass surgery uses a heart-lung machine to keep your blood and oxygen flowing through your body. Off-pump or beating-heart surgery does not stop your heart during surgery.
Minimally invasive procedures are also available where your coronary bypass is performed through small cuts in your chest and often uses robotics and video imaging to help your surgeon operate in a small area.
Your surgeon will discuss the options with you in detail.
Coronary artery bypass grafts last around 15 years but this varies from person to person. After that, another intervention, typically stent insertion, is usually required. If stenting is not suitable then another heart bypass may be performed.
As CABG does not cure your CHD, you should look after your heart health by following lifestyle recommendations and taking any prescribed medication.
Open-heart surgery is when your surgeon makes a large cut in your chest to access and repair a fault or damage in your heart. Open-heart surgery can be performed on the muscles, valves, or arteries of your heart.
Heart bypass surgery is traditionally an open-heart surgery, used to treat blocked or narrowed arteries. It involves opening your chest with a large cut, then taking healthy blood vessels from elsewhere in your body and attaching them to a blocked coronary artery so that your blood can bypass the blockage or narrowing.
The recovery process after your coronary artery bypass graft will depend on how it is performed. Also, everyone recovers at different rates.
After open CABG surgery, you will typically spend one to two days in an intensive care unit (ICU) and most people stay in hospital for at least seven days. You will be given information on recovering at home and making lifestyle changes to reduce your risk of heart disease. You should take things easy for a few weeks.
Expect to be able to return to most of your normal activities after about six weeks, including working and driving. Most people make a full recovery within 12 weeks.
You will have a follow-up appointment about six weeks after your operation.
If you have a minimally invasive coronary bypass, you can expect to leave the hospital sooner and have a faster recovery.
You will receive a formal quotation price for your coronary artery bypass graft following your consultation and any required tests with one of our expert cardiothoracic surgeons. This formal quote for your CABG will be valid for 60 days and includes unlimited aftercare.
