What is an aortic valve disorder?

Abnormal valve. The aortic valve is the valve leading out of the heart to the aorta. It may be thickened or calcified. It may then become narrowed. It may also leak. It may become infected, causing damage.
Aortic valve. The valve opens to allow flow out of the heart to the body. If it doesn't open properly we call this stenosis. It has to close properly to keep blood flowing in a forward direction. If it doesn't we call this insufficiency. Either or both abnormalities can exist in the valve.
