The value of two dimensional echocardiography in identifying communications between the ascending aorta and pulmonary trunk or individual pulmonary arteries was assessed in 24 children, all of whom had either angiocardiographic and surgical or angiocardiographic confirmation alone. Fourteen cases had truncus arteriosus, four aortopulmonary window, four anomalous origin of the left pulmonary artery from the ascending aorta, and two anomalous origin of the right pulmonary artery from the ascending aorta. It was possible to identify reliably each individual abnormality with a combination of suprasternal, precordial, and subcostal cuts. Problems only arose in differentiating truncus arteriosus from pulmonary atresia and ventricular septal defect when the main pulmonary artery and infundibular region of the right ventricle were extremely hypoplastic.
对24名儿童进行了评估，以确定二维超声心动图在识别升主动脉与肺动脉干或各条肺动脉之间交通方面的价值，所有这些儿童均通过心血管造影和手术或仅通过心血管造影得到确诊。14例为共同动脉干，4例为主动脉肺动脉窗，4例为左肺动脉起源于升主动脉异常，2例为右肺动脉起源于升主动脉异常。通过胸骨上、心前区和肋下切面相结合，能够可靠地识别每一种单独的异常情况。仅当主肺动脉和右心室漏斗部极度发育不全时，在鉴别共同动脉干与肺动脉闭锁及室间隔缺损方面才出现问题。
