Nowadays, the increasing numbers of heart diseases cases is very worrying although the medication technologies are always improving and moving forward. In this study, the objectives are to investigate the effect of blood flow velocity and leaflet displacement by using different shape of simplified two dimensional heart valve leaflets in the diastolic and systolic condition. Five different shapes of mitral valve leaflets and aortic valve leaflets were created and the simulation was performed by using ADINA-Fluid Structure Interaction. From the result obtained, triangle shape of leaflet showed it had the highest of blood velocity changes and leaflets displacement changes in a period time of one second when compare to the other four shapes whereas the square shape had the lowest performances. The relationship obtained for blood velocity flow and leaflet’s displacement changes is same for both mitral valve and aortic valve. The velocity of flow and leaflet’s displacement changes for triangle shape in diastolic condition is 68.54 mm/s and 2.171 mm while at systolic condition is 102 mm/s and 5.168 mm respectively for mitral valve. The outcome simulation result shows that large vortex formed behind the leaflet and leaflet deformed when the blood flow into left ventricle is agreed with the result in literature. In conclusion, five different shapes two-dimensional model of mitral valve and aortic valve has been developed and ellipse shape of valve leaflets is predicted to be the most suitable shape in applying for future artificial valve designing due to its good blood velocity flow with the small changes of leaflets displacement. Ellipse shape of leaflets could be chosen as the most suitable shape among these five shapes in further study of heart valve simulation. |
