The 2-dimensional echocardiographic features of interruption of the aortic arch are presented based on analysis of the echocardiograms and angiograms from 8 infants: 2 with type A and 6 with type B interruption. Each infant had a patent ductus arteriosus, 6 had a conoventricular septal defect with leftward deviation of the conal septum, 1 had truncus arteriosus with truncal valve stenosis, and 1 had a distal aortopulmonary septal defect with an intact ventricular septum. Echocardiographic images obtained from the suprasternal notch or from a high parasternal approach demonstrated the interruption of the aortic arch and continuation of the patent ductus arteriosus into the descending aorta. These findings were compared with those in infants with aortic atresia and a hypoplastic ascending aorta or discrete coarctation of the aorta with tubular hypoplasia of the aortic arch. Types A and B interruption of the aortic arch were easily differentiated and the caliber of the patent ductus arteriosus was assessed. The characteristic conoventricular septal defect was readily visualized froma an apex 2-chamber view or from a subcostal sagittal plane view. With this information subsequent angiography can be more expeditiously performed in this group of critically ill infants.
基于对8例婴儿的超声心动图和血管造影分析，呈现主动脉弓中断的二维超声心动图特征：2例为A型中断，6例为B型中断。每例婴儿均有动脉导管未闭，6例有圆锥室间隔缺损伴圆锥间隔向左偏移，1例有共同动脉干伴共同动脉干瓣膜狭窄，1例有远端主肺动脉间隔缺损且室间隔完整。从胸骨上切迹或高胸骨旁切面获得的超声心动图图像显示主动脉弓中断，动脉导管未闭延续至降主动脉。将这些发现与主动脉闭锁、升主动脉发育不良或主动脉弓管状发育不良的主动脉缩窄婴儿的发现进行比较。主动脉弓A型和B型中断易于区分，并评估了动脉导管未闭的管径。特征性的圆锥室间隔缺损从心尖二腔视图或肋下矢状平面视图中很容易看到。有了这些信息，随后可以在这组危重症婴儿中更迅速地进行血管造影。
