Aortic stenosis

Aortic stenosis is a heart valve disorder that narrows or obstructs the aortic valve opening. Narrowing of the aortic valve prevents the valve from opening properly and obstructs the flow of blood from the left ventricle to the aorta. This can reduce the amount of blood that flows forward to the body.
