WebAortic stenosis. The aortic valve area is normally 3.0 to 4.0 cm 2. Aortic stenosis is a progressive disease that leads to a gradual reduction in the orifice area. As the area is reduced, transvalvular flow resistance increases. This results in increased left ventricular load, while simultaneously affecting systemic perfusion.
