【摘要】：目的应用时间-空间关联成像(STIC)-M模式测量三尖瓣瓣环收缩期位移(TAPSE),探讨TAPSE定量评价胎儿右心收缩功能的价值。方法应用M型超声心动图及STIC-M模式成功测量正常中晚孕胎儿TAPSE 170胎,每个孕周10胎,比较两种方法测量结果是否存在差异。分析TAPSE与孕周(GA)、胎儿体质量预测值(EFW)、三尖瓣口舒张早期血流峰值速度(E)、舒张晚期血流峰值速度(A)的相关性。结果应用STIC-M模式和M型超声心动图测量TAPSE结果差异无统计学意义。应用STIC-M模式测得的TAPSE与GA、EFW、E、A呈显著相关性(P均0.001)。结论正常中晚孕胎儿TAPSE随GA、EFW增加而增长,与E、A等传统右心功能评价参数显著相关。STIC-M模式测量TAPSE具有简单、可重复性强、受胎儿体位影响小的特点,可作为一种新的准确评估胎儿右心功能的方法。
[Abstract]:Objective to measure the systolic displacement of tricuspid annulus using STIC-M mode in time-space correlation imaging (STIC-M). Methods M-mode echocardiography and STIC-M mode were used to measure fetal right ventricular systolic function. 10 fetuses per gestational week were compared for the difference between the two methods. Analysis of TAPSE and gestational weeks, fetal body mass prediction value (EFW). Early diastolic peak velocity of tricuspid valve. Peak late diastolic flow velocity. Results there was no significant difference in the results of TAPSE measured by STIC-M mode and M-mode echocardiography. The TAPSE and GA measured by STIC-M mode were not significantly different. There was a significant correlation between TAPSE and E. conclusion the TAPSE of normal middle and late pregnant fetus increased with the increase of GAEFW. The traditional right heart function evaluation parameters such as A were significantly correlated. STIC-M model was simple, reproducible and less affected by fetal posture. It can be used as a new method to evaluate fetal right ventricular function accurately.

【正文快照】： 胎儿心功能不全见于胎儿期许多疾病,如先天性心脏病、胎儿宫内发育迟缓、双胎输血综合征、特发性水肿、胎儿心律失常等,也可见于孕妇有妊娠期合并症的胎儿,如妊娠合并糖尿病、妊娠合并先兆子痫等,这些妊娠期合并症也是高危妊娠胎儿宫内死亡的重要原因之一[1-2]。快速准确评估
