title: [Methodological problems of quantitative and combined evaluation of the asynergy and volume of the left heart ventricle by contrast ventriculography in patients with ischemic heart disease].
abstract: Regional analysis was performed in 24 patients with various forms of left ventricular (LV) asynergy. Three quantitative methods of regional analysis with different types of superposition (SP) of end-phasic contours (EPC) were compared: the radial method, taking into account the dislocation of basal structures, was more sensitive (p less than 0.02) in detecting apical asynergy, as compared to the chordal method, or the radial procedure using a different type of SP. The authors used the radial method of regional analysis for estimating LV volumes in 53 patients. The data obtained with this method were in good correlation with those of the conventional "area-length" technique. It is concluded that the radial method taking into account the dislocation of basal structures is useful in complex and quantitative analysis of regional as well as systemic parameters of LV function.
