It is unclear why aortic stenosis causes syncope. One theory is that severe AS produces a nearly fixed cardiac output. [14] When a person with aortic stenosis exercises, their peripheral vascular resistance will decrease as the blood vessels of the skeletal muscles dilate to allow the muscles to receive more blood to allow them to do more work ...

Another important cause of aortic stenosis is chronic rheumatic fever, which can cause repeated inflammation and repair, leading to fibrosis. In this case, the leaflets can actually fuse together, called commissural fusion, which can be an important distinction from the type caused by mechanical stress over time.
Aortic stenosis and mitral stenosis are the most common examples. Major valves of the heart become stiffened and reduce the efficiency of the hearts pumping action. This may not cause symptoms at rest but with exertion, the heart is unable to keep up with increased demands leading to syncope.
Stenosis (from Ancient Greek στενός (stenós) 'narrow') is the abnormal narrowing of a blood vessel or other tubular organ or structure such as foramina and canals. It is also sometimes called a stricture (as in urethral stricture ).
