AORTIC VALVE ANATOMY
- The aortic root is a morphological physiological unit that is composed of the sinuses of Valsalva, three leaflets, and both coronary ostia, as well the three intervalvular triangles.
- From a strictly morphological point of view, the intervalvular triangles belong to the outflow tract of the left ventricle; however, from a functional point of view they belong to the aortic root.
- Thus, the aortic root structure is a compound of two morphological parts, namely the proximal part of the ascending aorta, including the area of the three leaflets, and the terminal part of the LV outflow tract
