Aortic stenosis

Aortic Stenosis, otherwise known as Aortic Valve Stenosis or sometimes just “AS”, is the narrowing of the heart’s aortic valve. The aortic valve controls the blood flow as it moves from the heart’s main pumping chamber (the left ventricle) to the aorta (the body’s main artery). The aortic valve opens to allow blood to move forward from the main pumping chamber into the aorta as the heart contracts, and then the aortic valve closes while the heart is relaxing. When aortic stenosis occurs, the aortic valve cannot open fully. Blood flow from the heart into the aorta is reduced or blocked, preventing blood from flowing on to the rest of the body properly.
