Investigation of human coronary arteries and heart ventricles mode of deformation and haemodynamics

Abstract

Mechanical properties of coronary arteries and heart tissues, computer 3D models of CA and heart ventricles were investigated. Numerical analysis of coronary arteries and heart ventricles mode of deformation and haemodynamics was made. The material of the arteries and heart tissue was assumed as linear isotropic, the blood as a Newtonian fluid. Comparative analysis of numerical data for cases of spatially unfixed coronary arteries and fixed coronary arteries of passive myocardium and for pathological and healthy heart ventricles was conducted.
