In this study influence of leaflet calcification on Aortic Valve calcification was studied using fluid solid interactions approach. The leaflets of the aortic valve were modeled as flexible structure. The interaction between flexible leaflets and blood flow was modeled with an iterative implicit method. The time averaged wall shear stress and pressure drop parameters were calculated for different models with various Young Modulus of elasticity for leaflets. Results revealed that more calcified leaflets are imposed to more wall shear stress and higher levels of pressure drop.
