目的：探讨产前超声心动图诊断胎儿三尖瓣下移畸形的临床价值。
Objective: To explore the clinical value of ultrasonic diagnosis of fetal Ebstein anomaly in prenatal.
提示右心发育受限，如肺动脉(瓣)狭窄、三尖瓣下移畸形。法洛氏四联症、右室双出口等。
This would thus suggest a right-sided restriction such as pulmonary stenosis, an Ebstein anomaly, tetralogy of Fallot, or a double-outlet right ventricle.
我还有一些尚未实施三尖瓣下移畸形根治治疗的患者，如果可能的话，我想与你讨论一下最适合他们的手术治疗方法。
I still have some cases of Ebstein's anomaly who did not received complete surgical correction, if possible, I would like to discuss with you about the best surgical treatment for them.
方法回顾性分析5例胎儿三尖瓣下移畸形（经胎儿心脏超声检查诊断）的超声图像与随访结果，分析各切面的二维声像和彩色多普勒血流特点。
Methods Retrospective analyses of 2D-heart views and CDFI(color Doppler flow image) as well as the follow-up findings were made in 5 cases with fetal Ebstein anomaly.
术后3月三尖瓣环下移距离有所增大（P<0.05）；
The SD of tricuspid annuli began to increase 3 month after operation (P<0.05).
患者较正常对照组心脏二尖瓣环、三尖瓣环下移距离显著减小（P<0.01），二尖瓣E波最大流速显著增大（P<0.01）；
The SD of mitral and tricuspid annuli were more lower than control group (P<0.01), and E velocity of mitral flow is higher (P<0.01) .
