Cross-sectional echocardiography has enabled us to demonstrate foetal cardiac structures, however, only a few studies have been reported. This report deals with a recently experienced foetus with double outlet right ventricle )DORV) diagnosed by this technique, confirmed by angiography and autopsy after birth. A 24-year-old pregnant woman with 24 weeks foetus underwent echocardiographic studies to evaluate the foetal heart because of its bradycardia. The cross-sectional echocardiogram showed a quite abnormal finding; i.e., two great arteries arose from the single ventricle which had coarse trabeculations. This finding suggested either DORV or single ventricle. The foetus was born at 40 weeks as a girl weighted 3040 g, and cyanosis was not observed. At one month of age, she began to experience increasing cyanosis by crying, and admitted to Keio Hospital for further examinations. She was performed catheterization and angiography, and was diagnosed as DORV. Cyanosis and dyspnea developed gradually and she died at the age of 2 months. Autopsy revealed DORV, polysplenia and dextrocardia.
横断面超声心动图使我们能够显示胎儿心脏结构，然而，相关报道仅有少数几例。本报告涉及近期经此技术诊断为右心室双出口（DORV）的一例胎儿，出生后经血管造影和尸检得以证实。一名怀有24周胎儿的24岁孕妇，因其胎儿心动过缓接受超声心动图检查以评估胎儿心脏。横断面超声心动图显示出极为异常的结果，即两条大动脉发自具有粗大肌小梁的单一心室。这一发现提示可能为右心室双出口或单心室。该胎儿于40周时出生，为一名体重3040克的女婴，未观察到发绀。出生1个月时，她开始在哭闹时出现发绀加重的情况，并入住庆应医院做进一步检查。她接受了心导管检查和血管造影，被诊断为右心室双出口。发绀和呼吸困难逐渐加重，她于2个月大时死亡。尸检显示为右心室双出口、多脾和右位心。
