2. Figure 1
Schematic drawing of the aortic root with graphic description of geometric height. AN, Aortoventricular junction; gH, geometric height; STJ, sinotubular junction; sinus, maximal sinus diameter; 1, shortest distance from aortic insertion to coaptation line; 2, distance assuming a straight course of the cusp and a coaptation height of 4 mm; 3, maximum geometric height assuming the effective height is equal to the coaptation height.
