Aortic Stenosis
In aortic stenosis, the aortic valve does not open normally. Compare the relatively closed aortic valve in aortic stenosis to the valve opening in a normal heart. Because the left ventricle must pump extra hard to eject blood across the stenotic valve, the left ventricular free wall and inter-ventricular septum are markedly thickened. However, there is no enlargement of the heart chambers or arteries.
