To determine whether the addition of the aortic-root view would detect more congenital cardiac anomalies than a standard four-chamber view alone.
The study included fetuses of 14 weeks' gestation or more who were scanned in our unit during a 28-month period. Outcome information was obtained from postnatal echocardiograms and autopsies. Abnormal hearts were classified as to whether the four-chamber or aortic-root view was abnormal.
There were 5967 fetuses in whom a four-chamber view could be obtained. In 5111 of these, an aortic-root view could also be obtained. The four-chamber view detected 24 (47%) of the 51 fetuses with abnormal hearts. Adding the aortic-root view increased the sensitivity to 78%.
Visualization of the aortic root is a quick and easy means of evaluating the aortic outflow tract during routine scanning. Adding the aortic-root view to the standard four-chamber view will result in the detection of most cardiac anomalies prenatally.
确定增加主动脉根部视图是否比单独使用标准四腔心视图能检测出更多先天性心脏异常。
该研究纳入了在28个月期间于本单位接受扫描的妊娠14周及以上的胎儿。结局信息来自产后超声心动图和尸检。异常心脏根据四腔心视图或主动脉根部视图是否异常进行分类。
有5967例胎儿可获得四腔心视图。其中5111例还可获得主动脉根部视图。四腔心视图在51例心脏异常胎儿中检测出24例（47%）。增加主动脉根部视图后敏感性提高到78%。
在常规扫描期间，观察主动脉根部是评估主动脉流出道的一种快速且简便的方法。在标准四腔心视图基础上增加主动脉根部视图将能在产前检测出大多数心脏异常。
