Abstract
Background: Demonstration of blood flow direction inside cardiac chambers can provide valuable information in normal subjects and pathologic cardiac processes. In our center we have already created a software able to generate the left ventricle (LV) model, the most important chamber of the heart. Method: The fundamental quantity that describes the motion of the fluid is represented by the vorticity defined as the tendency of fluid elements to spin; more precisely, vorticity can be related to rotation of fluid elements and the formation of circulatory areas. Quantitative parameters of the intra-ventricular vortex were also extracted on the basis of the vorticity. Result: In the left ventricle: blood flows through the mitral valve, hits the lateral left ventricular free wall, turbulences clockwise at the apex of the heart, hits the septal wall and flows towards the aortic valve. Conclusion: Technical points in our field of study can succeed us to gain a good understanding about the material. For blood flow direction inside the left ventricle, we can propose some tricky points: 1-Factors affecting blood direction inside the left ventricle? 2-Why does the blood flow at the present direction inside the left ventricle?
