目的探讨超声心动图检测孕12-14周胎儿三尖瓣反流的可行性及其临床意义。方法对614例孕12-14周高危孕妇的胎儿超声心动图检查结果进行分析,对早期三尖瓣反流的检出率、三尖瓣反流情况及相关原因进行探讨。结果共检出三尖瓣反流68例,检出率为11%,胎儿水肿、先天性心脏病、心律失常、宫内窘迫、孕妇糖尿病是胎儿早期中～重度三尖瓣的常见原因。结论超声心动图能检测孕早期胎儿三尖瓣反流,分析反流原因,评估预后,有重要的临床应用价值。
Objective To investigate the feasibility and clinical significance of echocardiography in the detection of fetal tricuspid regurgitation during 12-14 weeks of gestation. Methods The results of fetal echocardiography in 614 pregnant women at high risk of 12-14 weeks were analyzed. The detection rate of early tricuspid regurgitation and the causes of tricuspid regurgitation were discussed. Results Totally 68 cases of tricuspid regurgitation were detected, with a detection rate of 11%. Fetal edema, congenital heart disease, arrhythmia, intrauterine distress and maternal diabetes were the common causes of moderate to severe tricuspid valve in early stage of fetus. Conclusion Echocardiography can detect tricuspid regurgitation in the first trimester of pregnancy, analyze the causes of reflux, evaluate the prognosis, and have important clinical value.
