Figure 2 The effective height (hE) as a function of annulus diameter (dAA) under a pressure load of 3 mm Hg. The Journal of Thoracic and Cardiovascular Surgery 2013 145, 406-411.e1DOI: (10.1016/j.jtcvs.2012.01.080) Copyright © 2013 The American Association for Thoracic Surgery Terms and Conditions

Figure 3 Projected deformed configurations of the closed valves on the C-C plane with r = 5 mm and views from the aorta. The case of dAA = 28 mm is open with discontinuous contact, although the aorta view dose not disclose this fact.
