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.
Components [edit]. The aortic root is the portion of the ascending aorta beginning at the aortic annulus and extending to the sinotubular junction. Between each commissure of the aortic valve and opposite the cusps of the aortic valve, three small dilatations called the aortic sinuses.t the union of the ascending aorta with the aortic arch the caliber of the vessel is increased, owing to a bulging of its right wall. This dilatation is termed the bulb of the aorta, and on transverse section presents a somewhat oval figure.
