IMPACT OF MATERIAL STIFFNESS AND ANISOTROPY ON COAPTATION CHARACTERISTICS FOR AORTIC VALVE CUSPS RECONSTRUCTED FROM PERICARDIUM

Impact of Material Stiffness and Anisotropy on Coaptation Characteristics for Aortic Valve Cusps Reconstructed from Pericardium

The numerical assessment of reconstructed aortic valves competence and leaflet design optimization rely on both coaptation characteristics and the diastolic valve configuration.These Boombox characteristics can be evaluated by the shell or membrane formulations.The membrane formulation is preferable for surgical aortic valve neocuspidization planni
