Aortic Valve Stenosis

Certain medical problems or conditions make it more likely that you will develop aortic valve stenosis:

• Calcium buildup. Aging can cause calcium buildup around the aortic valve, which can make the normally thin and flexible valve flaps thick and stiff. This is also called calcific aortic valve stenosis. Many of the things that increase the risk of atherosclerosis and heart disease are the same for aortic valve stenosis. They include smoking, Reference high cholesterol Opens New Window, Reference high blood pressure Opens New Window, Reference diabetes Opens New Window, and being male.
• Birth defect. Sometimes a person is born with a Reference bicuspid aortic valve Opens New Window Reference Opens New Window that has two flaps instead of the normal three. Over time, the valve becomes damaged and calcium builds up. As the valve narrows, less blood can flow through it.
• Infection. Reference Rheumatic fever Opens New Window can cause scar tissue to build up at the edges of the valve. Rheumatic fever is not common now. But if you had it as a child, your risk of aortic valve stenosis may be increased.
• Artificial valve. Aortic valve disease also may develop in an artificial aortic valve that is made from human or animal tissue.

Other things that increase the risk for aortic valve stenosis include:

• Kidney failure.
• Smoking.
