Your doctor will likely recommend valve replacement surgery if you have severe stenosis, especially if you have symptoms, unless you have other health problems that make surgery too risky.
Aortic valve replacement surgery
Aortic valve replacement surgery is typically an open-heart surgery. In an aortic valve replacement surgery, the damaged valve is removed and replaced with an artificial valve (mechanical or tissue).

If you decide to have surgery, you and your doctor will decide which type of valve is right for you. For help with this decision, see:

Bypass surgery with valve replacement surgery
If you are going to have valve replacement surgery, your doctor may suggest that you have a coronary angiogram/catheterization test. This test can show if you have blockages in your coronary arteries (as part of coronary artery disease). If you have serious blockages, your doctor may want to do a coronary artery bypass surgery at the same time as the valve replacement surgery. For more information, see Aortic Valve Stenosis: Treatment with Other Heart Diseases.
Transcatheter aortic valve replacement
Transcatheter aortic valve replacement is a new way to replace an aortic valve. It does not require open-heart surgery. It is a minimally invasive procedure that uses catheters in blood vessels to replace the aortic valve with a specially designed artificial valve. This procedure is available in a small number of hospitals. And it is not right for everyone. It might be done for a person who cannot have surgery or for a person who has a high risk of serious problems from surgery.
Balloon valvuloplasty is a less invasive procedure than surgery. It may be an option for some people who have aortic valve stenosis. Although the heart valve is not replaced, the narrowed opening is made larger.
