Authors present a new study of left ventricular local wall motion. A critical study about three methods is analysed. This original analysis method is based on the calculation of local ejection fractions from a mathematic model: a theoretical ideal systolic contour is evaluated from an ejection fraction value and for a left homogeneous contraction ventricular. The left regional wall motion is appreciated from the comparison between real systole and theoretical systole. On the one hand, this method has been studied in theory. On the other one, it has been validated in a group of 22 patients having not any cardiac anomaly. Then its use has been compared to the two classic radial and longitudinal methods in a twenty ventriculographies group with six different contraction anomalies. Regularly, it was used on about more than 1500 valvular and coronary patients since November 1981. The results of the left ventricular function study are coherent.
作者介绍了一项关于左心室局部壁运动的新研究。分析了一项关于三种方法的批判性研究。这种原始分析方法基于从数学模型计算局部射血分数：根据射血分数值评估理论理想收缩轮廓，并针对左心室均匀收缩情况。通过比较实际收缩期和理论收缩期来评估左心室区域壁运动。一方面，该方法已在理论上进行了研究。另一方面，它已在一组无任何心脏异常的22名患者中得到验证。然后，在一组有六种不同收缩异常的20例心室造影患者中，将其使用情况与两种经典的径向和纵向方法进行了比较。自1981年11月以来，该方法经常用于约1500多名瓣膜病和冠心病患者。左心室功能研究的结果是一致的。
