Commentary: Is simpler better?

It is critical to understand the anatomy of the aortic root in aortic valve repair for aortic insufficiency. There are ten structure in the aortic root: one anatomic crown-shaped aortic annulus, two coronary ostia, three aortic sinuses/three cusps/three interleaflet triangles, and four rings: virtual basal ring (functional aortic annulus), ventriculo-aortic junction (VAJ), ring of the aortic sinuses (largest diameter of the aortic root), and sinotubular junction (STJ). Among the ten structures, three structures are critical for the competency of AV, including the functional aortic annulus (basal ring), the cusps and the STJ.
