摘要 目的:运用组织多普勒成像技术对胎儿左右心先心病的心功能进行评估,旨在探讨组织多普勒技术在胎儿心功能评估中的应用价值,以及胎儿左右心先心病对心功能的影响。方法:选择2017年7月—2018年9月于云南省阜外心血管病医院进行产前胎儿超声心动图检查并确诊为胎儿左心系统先心病或右心系统先性病的53例患者为研究对象,运用组织多普勒超声成像技术测量二尖瓣及三尖瓣瓣环的Sm、Em、Am,并计算Em/Am、E/Em及MPI指数,与41例同孕周正常胎儿的相应心功能指标进行比较。结果:频谱多普勒测量所得二尖瓣及三尖瓣E峰、A峰、E/A值在病例组和对照组中无明显差异(P> 0.05);病例组MPI值大于对照组MPI值;CVPS评分病例组小于对照组,结果表现出显著差异性(P <0.05),但在两个亚组的比较中无明显差异(P> 0.05)。结论:组织多普勒成像技术较传统的胎儿心功能评价方法而言,更加敏感、可重复性更高,有广阔的应用前景。
