用二维超声心动图研究了100例新生儿主动脉缩窄患者，其诊断全部为心血管造影、手术和病理解剖所证实。结果显示：87例诊断无误，2例诊断为主动脉断离而手术发现为重度主动脉缩窄。3例假阴性，8例仅见主动脉弓发育稍差或降主动脉扩张征象，未能肯定诊断。无假阳性。敏感度为87％，特异性100％。超声心动图对本病及伴随畸形做出准确的诊断，安全、可靠，对大部分病例可避免有创伤性检查，争取时机纠治，并为合并畸形的根治创造了条件。
100 cases of neonatal aortic constriction were studied by two-dimensional echocardiography. The diagnosis was confirmed by angiography, surgery and pathological anatomy. The results showed that 87 cases were correct, 2 cases were diagnosed as aortic disconnection and the operation was found to be severe aortic constriction. 3 cases false negative, only 8 cases of aortic arch development or less aortic dilatation signs, failed to confirm the diagnosis. No false positives. Sensitivity was 87%, specificity 100%. Echocardiography accurate diagnosis of the disease and accompanying malformations, safe and reliable, in most cases can avoid traumatic examination, to fight for the timing and create conditions for the consolidation of deformity.
