• F-0814 CFD Analysis of Diastolic Flow Patterns by the use of a Three-Dimensional Model of the Left Ventricle

抄録

Flow patterns in the human left ventricle (LV) during early diastole were studied theoretically by means of CFD using a 3-D model of the LV in order to find out the relationship between the diastolic flow pattern and the shape of the aliasing area which appears in a color M-mode Doppler echocardiogram. It was found that a vortex, asymmetrically enlarged on the side of the aortic valve, formed in the LV close to the mitral orifice, surrounding the mainflow that headed to the apex of the LV. The aliasing area that appeared in a color M-mode image obtained with CFD analysis was similar in shape to that obtained clinically. However, it did not agree quantitatively with that in clinically measured. It was considered that this was due to differences of size, birth place and developmental process of the vortex in the LV.
