"The mitral valve annulus is posterior and slightly inferior, and the anterior mitral valve leaflet is intimately connected to the noncoronary and left coronary cusps of the aortic valve by the intervalvular fibrous body. This structural link coordinates movement and force transmission between the aortic and mitral annuli during the cardiac cycle and ensures efficient left ventricular ejection and aortic valve competence 4,5,6. Calcification or dilatation of one annulus can impact the function of the adjacent valve and alter the electrical interface."
"The size and shape of the aortic annulus dictate the sizing and placement of prosthetic valves. The annulus is more circular in systole and more elliptical in diastole, and changes with age. Accurate CT angiography measurements minimise complications such as paravalvular leak, prosthesis-patient mismatch, and annular rupture during TAVR or surgical valve replacement. A small or calcified aortic annulus increases the incidence of procedural complications and influences the choice of valve."

"The noncoronary cusp is supported by fibrous tissue, whereas the right and left coronary cusps are supported by muscle and fibrous tissue. The aortic annulus is contiguous with the left and right fibrous trigones and the membranous septum, which are key components of the central fibrous body. The annulus has an important role in maintaining aortic valve competence and preventing regurgitation; dilation or distortion can lead to valvular insufficiency."
