A combined angiocardiographic-echocardiographic method for estimating right ventricular wall mass is described. Biplane cineangiocardiograms are analyzed for ventricular volume in end-diastole, and wall thickness is determined from echocardiograms obtained with a high frequency transducer and strip chart recorder, The intracavitary and the external surface volumes of the ventricle are derived, and the difference multiplied by 1.050, the specific gravity of myocardium. Excellent correlation was observed between right ventricular wall mass and body surface area in normal children (r = 0.93). The mean right ventricular mass was 44.5 g/M2 as compared to 78.1 g/M2 for the left ventricle, corresponding mass/EDV values were 0.48 g/cm3 and 1.26 g/cm3, respectively. In isolated right ventricular pressure overload, the increase in right ventricular mass is chiefly due to the increase in wall thickness; in volume overload, it is due mostly to the increase in chamber volume,
本文描述了一种用于估计右心室壁质量的心血管造影与超声心动图联合方法。分析双平面电影心血管造影图以确定舒张末期心室容积，并通过高频换能器和带状图表记录仪获得的超声心动图确定壁厚度。得出心室内腔和心室外表面容积，二者差值乘以心肌比重1.050。在正常儿童中观察到右心室壁质量与体表面积之间具有良好的相关性（r = 0.93）。右心室平均质量为44.5 g/M²，而左心室为78.1 g/M²，相应的质量/舒张末期容积值分别为0.48 g/cm³和1.26 g/cm³。在单纯右心室压力过载时，右心室质量增加主要归因于壁厚度增加；在容量过载时，主要归因于心腔容积增加。
