Ultrasonic studies were performed in 19 neonates with the hypoplastic left heart syndrome whose diagnosis was confirmed at angiography or autopsy, or both. The patients were classified in two echocardiographic groups: Group I, 10 infants whose ventricular septum could be recorded, and Group II, 9 infants whose septum could not be recorded. The findings in these groups were compared with those in 60 neonates without congenital heart disease also studied with ultrasound. Two additional neonates who presented with signs of shock were also studied. The diagnostic echocardiographic features of hypoplastic left heart syndrome were: (1)a left ventricular end-diastolic dimension of less than 9 mm; (2)an aortic root diameter of less than 6 mm; (3)a ratio of left ventricular end-diastolic to right ventricular end-diastolic dimension of less than 0.6; and (4)a mitral valve echo that is absent or greatly distorted and of small amplitude. These echocardiographic criteria differed significantly from findings in the normal group (P less than 0.01). Echocardiography proved valuable in neonates with shock. It is a safe, reliable technique that can be used to delineate the intracardiac anatomy in sick neonates with the hypoplastic left heart syndrome.
对19例左心发育不全综合征新生儿进行了超声检查，这些患儿的诊断经血管造影或尸检或两者均证实。将患儿分为两个超声心动图组：第一组，10例可记录室间隔的婴儿；第二组，9例无法记录室间隔的婴儿。将这些组的检查结果与60例同样接受超声检查的无先天性心脏病的新生儿的结果进行比较。还对另外2例出现休克体征的新生儿进行了研究。左心发育不全综合征的诊断性超声心动图特征为：（1）左心室舒张末期内径小于9毫米；（2）主动脉根部直径小于6毫米；（3）左心室舒张末期内径与右心室舒张末期内径之比小于0.6；（4）二尖瓣回声缺失或严重扭曲且幅度小。这些超声心动图标准与正常组的结果有显著差异（P小于0.01）。超声心动图对休克新生儿很有价值。它是一种安全、可靠的技术，可用于描绘患有左心发育不全综合征的患病新生儿的心内解剖结构。
