Aortic annulus
Dr Azza Elgendy ◉ et al.
The aortic annulus is a fibrous ring at the aortic orifice to the front and right of the atrioventricular aortic valve and is considered the transition point between the left ventricle and aortic root. The annulus is part of the fibrous skeleton of the heart. It is at the level of the sinus of Valsalva and is the site of aortic valve leaflet insertion.
