胎儿三尖瓣发育异常的产前超声诊断

The evaluation of fetal echocardiography in diagnosis of tricuspid malformation

目的探讨超声心动图产前诊断胎儿三尖辫发育异常的临床价值。方法回顾性分析2010年1月～2012年10月在我院经胎儿超声心动图检查诊断为三尖瓣发育异常的310例病例的临床资料。结果在诊断三尖瓣发育异常的310例病例中，三尖辫闭锁42例（13．55％），三尖瓣下移畸形9例（2．90％），三尖瓣狭窄7例（2．26％），三尖瓣发育不良5例（1．61％），单纯性三尖瓣反流247例（79．68％），其中轻度反流207例，中度反流25例，重度反流i5例。所有病例中，生后及尸检病例共142例，失访168例。结论胎儿超声心动图可以清晰的显示三尖瓣结构、三尖瓣口血流，评价胎心血流动力学。胎儿超声心动图可供诊断先天性三尖辫发育异常，为产前诊断提供必要的依据。

Objective To explore the value of fetal echoeardiography in diagnosis of tricuspid malformation. Meth- ods Fetal echocardiography characteristics of 310 fetuses with tricuspid malformation were analyzed retrospectively from January 2010 to October 2012. Results There were 42 cases with tricuspid atresia （13.55%）, 9 cases with Ebsteiffs a- nomaly （2.9%）, 7 cases with tricuspid stenosis （2.26%）, 5 cases with tricuspid hypoplasia （1.61%）, 247 cases with simple tricuspid regurgitation （79.68%）, including 207 cases of mild reflux, 25 cases of moderate regurgitation, 15 cases of severe reflux. In all eases, 142 eases were after birth and autopsy eases and 168 cases were lost to follow. Conclusion Fetal eehocardiography clearly displays tricuspid pattern of thickening and mobility. CDFI could detect the flow through the tricuspid valve and evaluate the hemodynamics. Fetal echocardiography is an important method in prenatal diagnosis of tricuspid malformation.
