In recent years, fetal echocardiography has greatly improved in that most major structural heart defects are detectable from 18 weeks on. Fetal M-mode mapping has also enabled us to detect and diagnose fetal arrhythmias as well as follow their treatment. More recently, pulsed Doppler and color-flow mapping have facilitated the dynamic study of blood flow in the cardiovascular system. Fetal echocardiography has now become a sophisticated modality, but is a crucial one to master because most fetuses that have congenital heart defects are not necessarily at any high risk. Evaluation of the fetal heart, therefore, is a recommended part of the routine fetal structural survey.
近年来，胎儿超声心动图有了很大改进，大多数主要的心脏结构缺陷在孕18周起就可检测到。胎儿M型超声心动图也使我们能够检测和诊断胎儿心律失常，并跟踪其治疗情况。最近，脉冲多普勒和彩色血流图有助于对心血管系统中的血流进行动态研究。胎儿超声心动图现已成为一种复杂的检查方式，但却是一项必须掌握的关键技术，因为大多数患有先天性心脏缺陷的胎儿不一定处于任何高风险状态。因此，对胎儿心脏的评估是常规胎儿结构检查中推荐的一部分。
