Aortic valve stenosis can occur because of a birth defect in the formation of the valve. Calcium deposits may form on the valve with aging, causing the valve to become stiff and narrow. Stenosis can also occur as a result of rheumatic fever.
Valvular stenosis can be a congenital defect (develops in the fetus and is present at birth) or can be acquired, that is to stem from other conditions.

Aortic valve replacement is necessary when the aortic valve has become diseased. The aortic valve can suffer from insufficiency (inability to perform adequately) or stenosis.
There is no medical treatment that reverses the progress of aortic valve stenosis. Aortic valve replacement is the only solution to this problem. However, surgery is not always necessary. Aortic valve stenosis can be monitored with echocardiography if surgery is not initially indicated. In addition, for patients who are not candidates for surgical valve replacement, there are percutaneous and catheter-based valve replacement procedures available.

A stenosed valve is a valve that has been narrowed for some reason; either by injury, scar tissue or congenital anomaly. Depending on the level of stenosis, cardiac output can be fixed (unable to be changed) and reduced.

3 - 4cm3, it becomes reduced in aortic stenosis and is usually symptomatic at less than 1cm3
Osteomalacia is the opposite of osteosclerosis.
Common symptoms of aortic valve stenosis are chest pains, feeling faint, shortness of breath, and fatigue. More serious symptoms include having heart failure.
Anyone with aortic stenosis needs to take antibiotics (amoxicillin, erythromycin, or clindamycin) before dental and some other surgical procedures, to prevent a heart valve infection.
Balloon valvotomy may provide short term relief of aortic stenosis, but is considered palliative until valve replacement can be accomplished.
