Cusp height in aortic valves Hans-Joachim Schäfers, MD, Wolfram Schmied, Dipl Psych, Gil Marom, MSc, Diana Aicher, MD The Journal of Thoracic and Cardiovascular Surgery Volume 146, Issue 2, Pages 269-274 (August 2013) DOI: 10.1016/j.jtcvs.2012.06.053 Copyright © 2013 The American Association for Thoracic Surgery Terms and Conditions

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.
