Echocardiography was used in 40 patients with atrial septal defect (ASD), diagnosed by cardiac catheterization. A dilated right ventricle and abnormal interventricular septal motion were observed at M-mode echocardiography in patients with large L-R shunt. The two-dimensional apical four chamber view was reliable to detect the ostium primum type but not the secundum type of ASD. Moreover the presence of false positives reduced the specificity and predictivity of this approach. The two-dimensional subcostal view provided a direct visualization of the interatrial communication (sensitivity, specificity and predictivity = 100%) and whether the defect was in the uppermost, lowermost or midportion of the septum. Subcostal two-dimensional echocardiography is considered valuable and reliable technique to detect atrial septal defect and the type of the defect itself.
对40例经心导管检查确诊为房间隔缺损（ASD）的患者进行了超声心动图检查。在M型超声心动图中，大的左向右分流患者观察到右心室扩张和室间隔运动异常。二维心尖四腔心切面对于检测原发孔型房间隔缺损可靠，但对于继发孔型不可靠。此外，假阳性的存在降低了该方法的特异性和预测性。二维肋下切面可直接显示房间隔交通（敏感性、特异性和预测性均为100%）以及缺损位于房间隔的最上部、最下部还是中部。肋下二维超声心动图被认为是检测房间隔缺损及其缺损类型的有价值且可靠的技术。
