Aortic valve stenosis is usually defined by restricted systolic opening of the valve leaflets, with a mean transvalvular pressure gradient of at least 10 mm Hg. The cause of the stenosis can be further defined based on the anatomy and disease process affecting the valve.
Aortic Stenosis Symptoms. Aortic stenosis is the narrowing of the aortic valve, which limits the aortic valve leaflet's ability to fully open and close. Valve leaflets are flaps of tissue that open and close to regulate the one-way flow of blood through the aortic valve.alcification is the process that refers to the build-up of calcium on the heart's valves. In elderly patients, aortic stenosis is sometimes caused by the build-up of calcium (mineral deposits) on the aortic valveâs leaflets. Over time the leaflets become stiff, reducing their ability to fully open and close.
