It is characterized by restricted outflow from the LEFT VENTRICLE into the AORTA. MESH:D001024 Aortic valve stenosis (disorder) SNOMEDCT:420503003 Aortic Valve Stenosis Stenoses, Aortic DOID:1712 NCIt:C64938 Stenosis, Aortic Valve SNOMEDCT:60573004 MedDRA:10002906 Aortic valve stenosis is a aortic valve disease caused by the incomplete opening of the aortic valve. The aortic valve controls the direction of blood flow from the left ventricle to the aorta. When in good working order, the aortic valve does not impede the flow of blood between these two spaces. Under some circumstances, the aortic valve becomes narrower than normal, impeding the flow of blood. This is known as aortic valve stenosis, or aortic stenosis, often abbreviated as AS.
