目的研究三尖瓣反流超声心动图特征与快速诊断出先天性心脏病的类型的关联性。方法选择2010年至2015年行产前彩超检查并诊断出有三尖瓣反流特征的胎儿138例,按照三尖瓣反流类型分成生理组(生理性三尖瓣反流)和病理组(病理性三尖瓣反流),每组69例。分析并对比两组胎儿三尖瓣反流相关参数与先天性心脏病的关系。结果三尖瓣反流相关参数右心室与左心室横径比值(DRV/DLV)、右室壁与左室壁的厚度比值(TRV/TLV)组间比较差异未见统计学意义(P>0.05),其他相关指标如最大三尖瓣反流速(VTR)、反流速根部宽度(WTR)、反流持续时间与心室收缩时间比值(TTR/TS)等组间比较差异有统计学意义(P均<0.05)。结论胎儿三尖瓣反流超声心动图的相关参数的变化能快速准确地诊断出先天性心脏病的疾病类型。
Objective To study the association between tricuspid regurgitation echocardiography and rapid diagnosis of congenital heart disease. Methods 138 cases of fetuses with tricuspid regurgitation were diagnosed by prenatal color Doppler ultrasonography between 2010 and 2015. They were divided into physiological group (physiological tricuspid regurgitation) and pathological group (pathological group Tricuspid regurgitation), 69 cases in each group. The relationship between fetal tricuspid regurgitation related parameters and congenital heart disease was analyzed and compared. Results There was no significant difference between DRV / DLV and TRV / TLV in the parameters of tricuspid regurgitation (P> 0.05 ), Other related indicators such as the maximum tricuspid regurgitation velocity (VTR), anti-reflux root width (WTR), duration of reflux and ventricular systolic time ratio (TTR / TS) were statistically significant difference between groups <0.05). Conclusion The changes of fetal tricuspid regurgitation echocardiography can quickly and accurately diagnose the disease type of congenital heart disease.
