Subxiphoid, two-dimensional echocardiograms (S2DE) were performed and interpreted before diagnostic cardiac catheterization on 59 neonates who weighed 1.3--6.0 kg (median 3.3 kg) and were 1--35 days old (median 4.5 days). The echocardiographic studies were successfully performed on 58 of 59 infants. Using appropriate longitudinal and transverse projections, S2DE permitted simultaneous visualization of the branch pulmonary arteries, proximal thoracic aorta and ventriculoarterial attachments. D-transposition of the great arteries was correctly predicted in all 16 infants with levocardia, situs solitus and atrioventricular concordance. In these patients, the standard left ventricular longitudinal projection demonstrated the bifurcating main pulmonary artery attached to the posterior ventricle; the transverse projection displayed the relationship of the proximal thoracic aorta to the anterior ventricle. The broad acoustical window using the subxiphoid approach in conjunction with a high-frequency focused transducer and a large active-element diameter permitted detailed imaging of intra- and supracardiac structures.
对59例体重1.3 - 6.0千克（中位数3.3千克）、年龄1 - 35天（中位数4.5天）的新生儿，在诊断性心导管检查前进行了剑突下二维超声心动图（S2DE）检查并解读。59例婴儿中有58例成功完成了超声心动图检查。通过适当的纵向和横向投照，S2DE能够同时显示分支肺动脉、胸段主动脉近端和心室动脉连接。在所有16例左位心、心脏位置正常且房室一致的大动脉转位（D-TGA）婴儿中，均正确预测出该疾病。在这些患者中，标准的左心室纵向投照显示分叉的主肺动脉附着于后方心室；横向投照则显示胸段主动脉近端与前方心室的关系。剑突下途径结合高频聚焦探头和大的有源元件直径所形成的宽阔声学窗，能够对心内和心外结构进行详细成像。
