Aortic stenosis is the gradual narrowing of the aortic valve opening. It results in greater resistance to blood flow from the left ventricle into the aorta; therefore increasing the amount of work required for the heart to pump blood adequately throughout the body.
The increased strain on the heart may cause it to weaken, eventually leading to heart failure. Further, an insufficient supply of oxygenated blood to all parts of the body, especially during intense physical exertion, can cause muscle pain, fainting and even spontaneous death.
Aortic stenosis can be the result of either a congenital defect of the aortic valve, or more commonly, calcification of the opening often associated with ageing.
