          Abstract

          We made a frame by frame analysis of the left ventricular cineangiogram to quantitate normal regional left ventricular function. Two different methods were used: contraction of the left ventricle towards a fixed point at the center of its long axis, and a pattern of contraction normal to the outline of the ventricle. Each method was used with and without correction for rotation and translational movement during systole. Left ventricular contraction and relaxation were represented graphically on a three-dimensional perspective plot and also using contour mapping techniques. The normal values and standard deviation were calculated for the extent, velocity and time course of ventricular contraction and relaxation in each region of the ventricle. The study provided a graphic visual display of the regional contractile pattern of the normal ventricle.
