An aortic valve replacement is a type of open heart surgery used to treat problems with the heart's aortic valve.
The aortic valve controls the flow of blood out from the heart to the rest of the body.
An aortic valve replacement involves removing a faulty or damaged valve and replacing it with a new valve made from synthetic materials or animal tissue.
It's a major operation that isn't suitable for everyone and can take a long time to recover from.
The aortic valve may need to be replaced for 2 reasons:
The problems can get worse over time and in severe cases can lead to life-threatening problems such as heart failure if left untreated.
There are no medicines to treat aortic valve problems, so replacing the valve will be recommended if you're at risk of serious complications but are otherwise well enough to have surgery.
An aortic valve replacement is carried out under general anaesthetic.
This means you'll be asleep during the operation and won't feel any pain while it's carried out.
During the procedure:
The operation usually takes a few hours. You'll have a discussion with your doctor or surgeon before the procedure to decide whether a synthetic or animal tissue replacement valve is most suitable for you.
You'll usually need to stay in hospital for about a week after an aortic valve replacement, although it may be 2 to 3 months before you fully recover.
You should take things easy when you first get home, but you can start to gradually return to your normal activities over the next few weeks.
You'll be given specific advice about any side effects you can expect while you recover and any activities you should avoid.
You won't usually be able to drive for around 4 to 6 weeks and you'll probably need 6 to 12 weeks off work, depending on your job.

An aortic valve replacement is a big operation and, like any type of surgery, carries a risk of complications.
Some of the main risks of an aortic valve replacement include:
The risk of dying from an aortic valve replacement is around 1 to 3%, although this risk is much smaller than that of leaving severe aortic valve problems untreated.
Most people who survive surgery have a life expectancy close to normal.
