Heart bypass & valve surgery

Heart (cardiac) bypass surgery

This operation moves a blood vessel from another part of your body to replace a blocked or narrowed blood vessel (artery) in your heart muscle. It is also called coronary artery bypass graft surgery (CABG).

When blood vessels that feed heart muscle are blocked or narrowed, it can cause angina (chest pains) or heart attacks.

You can read more details about heart bypass surgery on the Heart Foundation website.

Heart valve replacement

Your heart has four chambers and four valves (the aortic, pulmonary, mitral and tricuspid valves). These valves keep the blood flowing in one direction. Sometimes heart valves are too tight and don't open easily enough (called stenosis), and sometimes they are too floppy, which allows blood to flow in the wrong direction (regurgitation).

Heart valve problems can affect how your heart works, and can cause symptoms like shortness of breath, swollen ankles, and chest pain. They can even make you collapse.

Your cardiologist (heart specialist) will usually monitor any heart valve problems over time, using echo tests (echocardiograms). Your valves may eventually need to be either repaired or replaced.

If you need surgery on your heart you will be referred to a heart surgeon, also called a cardiothoracic surgeon.

You can read more about heart valve replacement on the Heart Foundation website.

Recovery after heart surgery

It is normal to experience some pain and discomfort after heart surgery. This leaflet gives detailed advice on what to expect after heart surgery, what medication you might receive, what you will and won't be able to do, exercises, and how long your recovery is likely to take.
