Aortic valve disease (AVD) is a condition in which the valve between the main pumping chamber of your heart (left ventricle) and the main artery to your body (aorta) doesn't work properly.
Other causes may result AVD include age-related changes to the heart (calcium deposits may cause the valves to become stiff and thickened), infections (from endocarditis or rheumatic fever), high blood pressure or injury to the heart (heart attack and heart failure).
Aortic valve disease may be a heart defect condition present at birth (congenital heart disease).
There are two commonly known types of aortic valve disease:
Aortic valve stenosis when the flaps (cusps) of the aortic valve may become stiff or fuse together. This causes narrowing of the aortic valve opening. The narrowed valve cannot open fully, which can block blood flow from the heart into the body (aorta) and the rest of the body.
Aortic valve regurgitation when the aortic valve doesn't close properly, causing blood to flow backward into the left ventricle.
