Routine ultrasound examination of the fetus is already established in most obstetric units in Britain. A simple method was devised to evaluate one section of the fetal heart systematically. Examination of this section, the four chamber view, may readily be incorporated into routine obstetric screening. Severe cardiac abnormalities detectable in this view occur in two per 1000 pregnancies. For six years the department of paediatric cardiology at Guy's Hospital, London, served as a referral centre for fetal echocardiography. As teaching became more widespread an increasing proportion of cases of cardiac anomaly were referred because the obstetrician suspected abnormality on examination of the four chamber view. Currently 80% of detected abnormalities are referred for this reason. Further extension and organisation of teaching might result in most severe cardiac malformations being detected in early prenatal life.
在英国，大多数产科单位已将胎儿常规超声检查确立为常规检查项目。人们设计了一种简单的方法来系统地评估胎儿心脏的一个切面。对这个切面（四腔心切面）的检查可以很容易地纳入常规产科筛查。在此切面上可检测到的严重心脏异常在每1000例妊娠中出现两例。伦敦盖伊医院儿科心脏病学系作为胎儿超声心动图转诊中心已有六年时间。随着教学的日益普及，越来越多的心脏异常病例被转诊，因为产科医生在检查四腔心切面时怀疑有异常。目前，80%的已检测到的异常是出于这个原因被转诊的。进一步扩展和组织教学可能会使大多数严重心脏畸形在产前早期被检测出来。
