Recent advancement in the MR imaging technology have enabled direct three-dimensional flow quantification in-vivo. However, the spatial and temporal resolution of MRI is still limited compared to 2D echocardiography, which has been suggested as a clinical guideline for various cardiovascular diseases, including mitral regurgitation. In this study, we have directly compared the accuracy of echocardiography and MRI in estimating the regurgitant flow rate using in-vitro mitral valve regurgitation model. The in-vitro mitral valve model was fabricated using the flexible silicon, and was able to mimic the movement of the mitral valve during the systolic phase using the pulsatile flow generated by the piston pump.
