A 4-month-old infant with cyanosis but without other abnormal cardiac findings is presented in whom the diagnosis of anomalous systemic venous connection to the left atrium was made by contrast echocardiography. The diagnosis was later confirmed by cardiac catheterisation and selective cineangiography. When saline was injected into a vein on the dorsum of each hand while echocardiographically recording the cardiac structures, the left atrium, left ventricle, and aorta were opacified without visualisation of the right ventricle. Similar study with injection into the right foot produced opacification of the right ventricle without visualisation of the left-sided structures. These data suggested normal drainage of the inferior vena cava with anomalous connection of the superior vena cava to the left atrium. A review of the previously reported cases of anomalous connection of the right superior vena cava to the left atrium is presented together with the possible embryological origin of this anomaly.
本文介绍了一名4个月大的婴儿，有发绀但无其他心脏异常表现，通过对比超声心动图诊断为体静脉异常连接至左心房。该诊断后来通过心导管检查和选择性心血管造影得到证实。在超声心动图记录心脏结构的同时，向每只手背部的静脉注射生理盐水，结果显示左心房、左心室和主动脉显影，而右心室未显影。向右脚注射进行类似研究时，右心室显影，而左侧结构未显影。这些数据提示下腔静脉引流正常，而上腔静脉异常连接至左心房。本文回顾了先前报道的右上腔静脉异常连接至左心房的病例，并探讨了这种异常可能的胚胎学起源。
