摘要
An experimental model for heart-mural coronary artery-myocardial bridge was established based on the theory of hemodynamics. The application of the model demonstrated that it can repeat to great extent the phenomenon of myocardial bridge compressing mural coronary artery that results in abnormal hemodynamic characteristic. The in vitro simulation experiment indicates that the anomaly of normal stress, circumferential stress and wall shear stress mainly occurs in the proximal end. As the oppression level increases, the mean proximal stress and the oscillatory value (maximum-minimum) increase obviously. The experimental model for heart-mural coronary artery-myocardial bridge provides a method to study relationship between myocardial bridge and atherosclerosis.
