Forty-five patients with either a ventricular septal defect or a persistent ductus arteriosus were assessed by echocardiography and cardiac catheterisation. Left atrial dimension was expressed either as a function of the body surface area (LAD cm per m2 BSA), or as a multiple of the aortic root dimension (LAD/AR), and was compared with the shunt size as determined by oximetry. A highly significant (P less than 0-001) regression relation was found for the group as a whole. A significant relation also existed for each individual group: ventricular septal defect, ventricular septal defect with pulmonary hypertension, and persistent ductus arteriosus. Regression equations were derived for the whole group. The value of echocardiography is in separating large from small shunts and in adding a dimension to the follow-up of the individual patient.
对45例患有室间隔缺损或动脉导管未闭的患者进行了超声心动图和心导管检查评估。左心房大小要么表示为体表面积的函数（每平方米体表面积的左心房内径，单位为厘米），要么表示为主动脉根部内径的倍数（左心房内径/主动脉根部内径），并与通过血氧测定法确定的分流大小进行比较。整个组发现了高度显著的（P小于0.001）回归关系。每个单独的组也存在显著关系：室间隔缺损、伴有肺动脉高压的室间隔缺损和动脉导管未闭。得出了整个组的回归方程。超声心动图的价值在于区分大分流和小分流，并为个体患者的随访增加一个维度。
