In 31 patients, aged 3 to 15 years, with atrial septal defects (secundum type) and varying degrees of left-right shunt volumes, 2-dimensional echocardiography was employed to assess the percent length of the defect with respect to total interatrial septal length. Visualization of the septum was achieved through the "4-chamber view" from the apical position (Figure 2). The calculated echocardiographic defect size was expressed in percent of the total interatrial septal length for comparison with the per cent shunt calculated from standard cardiac catheterization. There was good agreement in the patient group with defects found to be associated with less than 40% left-right shunt; in those with larger shunt volumes, the echocardiographically-determined values overestimated the oxymetrically-determined values (Figure 3). Thus, the results show that this non-invasive method is capable of providing useful information with respect to atrial septal defect size and subsequent indication for surgical closure.
对31例年龄在3至15岁、患有房间隔缺损（继发孔型）且左右分流程度各异的患者，采用二维超声心动图评估缺损长度占房间隔总长度的百分比。通过心尖位置的“四腔心切面”实现对房间隔的观察（图2）。计算得出的超声心动图缺损大小以房间隔总长度的百分比表示，以便与通过标准心导管检查计算出的分流百分比进行比较。在缺损与左右分流小于40%相关的患者组中，两者结果吻合良好；在分流较大的患者中，超声心动图测定值高估了血氧测定值（图3）。因此，结果表明这种非侵入性方法能够提供关于房间隔缺损大小以及后续手术闭合指征的有用信息。
