We collected 98 cases of single atrial septal defect. Analytical study of the pulmonary vasculature and the shape of the heart allowed us to differentiate 71 cases of pulmonary hypervascularity with increased cardiothoracic index and an appearance of right ventricular dilatation. The left inferior segment was usually straight, but sometimes convex, with a great curvature including the middle left segment. Apart from these 71 typical cases, there were 18 cases of incomplete patterns, 7 cases of atypical patterns with a convex left inferior segment with a small curvature and two normal cases (normal shape of the heart and normal vasculature). - Echocardiography was performed in 35 cases. It was valuable in 34 cases and established the diagnosis each time the X-ray picture was uncertain. Increase of the ratio of the telediastolic diameter of the right to left ventricle is almost constant and the septal motion is paradoxical in 79% of all cases. - Post-operative change was characterized from the radiological point of view by rapid return to normal of the pulmonary vascularity, followed by decrease of the cardiothoracic index, while the modifications of the shape of the left middle and inferior segment regress slowly and incompletely. As for echocardiography there is constant decrease of the ratio of the telediastolic diameter of the right to left ventricle, while the septal motion returns to normal in 79% of all cases.
我们收集了98例单纯房间隔缺损病例。通过对肺血管系统和心脏形态的分析研究，我们鉴别出71例肺血管增多伴心胸指数增加且有右心室扩张表现的病例。左下段通常是直的，但有时凸出，其大弯度包括左中段。除了这71例典型病例外，还有18例不完全型、7例左下段凸出且弯度小的非典型病例以及2例正常病例（心脏形态和血管系统正常）。——对35例患者进行了超声心动图检查。在34例中超声心动图很有价值，并且每当X线片结果不确定时它都能确立诊断。右心室与左心室舒张末期直径之比增加几乎是恒定的，在所有病例中有79%的患者室间隔运动呈矛盾运动。——从放射学角度来看，术后变化的特征是肺血管系统迅速恢复正常，随后心胸指数下降，而左中、下段形态的改变恢复缓慢且不完全。至于超声心动图，右心室与左心室舒张末期直径之比持续下降，在所有病例中有79%的患者室间隔运动恢复正常。
