Back to the Basics: Aortic Valve Anatomy Cardioserv
The aortic valve is composed of 4 key parts: Aortic Annulus; Aortic Root; Cusps/Leaflets; Commissures; Aortic Annulus. The aortic annulus is a functioning ring-like structure that anchors the base hinge-points of the aortic leaflets. We measure the aortic annulus diameter between the hinge points of the valve leaflets, commonly referred to as ...
