The patterns and characteristics of blood flow in the heart are the basis of exploring the mechanism of abnormal blood physiological parameters and pathological changes of heart tissue structure. In this paper, the left ventricular model was reconstructed and optimized based on Computed Tomography (CT) scan data. Combined with the motion characteristics of the myocardium wall, the mathematical model of the left ventricle geometric model was established, and the effect of mitral stenosis on the blood flow of the left ventricle was studied by using the dynamic grid technique. The hydraulic radius was used to represent the stenosis degree of mitral valve stenosis. It was found that the velocity and pressure at the inlet increased during systolic period, and the shear stress increased when the inlet area decreased. The velocity and pressure increase first and then decrease in diastolic period. When the hydraulic radius is small, the overall shear stress in the left ventricle is large, reaching a maximum of 4.60 Pa at 6/8T. In this paper, the simulation of the heart through dynamic simulation provides important reference value for the subsequent research on the heart.
