实时三维超声心动图Heart Model模式定量评价左室容量及左室射血分数

Quantitative evaluation of left ventricular volume and left ventricular ejection fraction by real-time 3D echocardiogram Heart Model

目的探讨三维超声心动图全自动左心定量技术(three-dimensional echocardiography Heart Model,3D-HM)在左室收缩功能评估中的应用价值。方法选取我院2018年1月~2019年5月健康体检的正常成年人58例,男24例,女34例。均采用常规M型超声、双平面辛普森法、二维心功能定量(2DQ)、三维自动化心功能定量(3DQA)、3D-HM分别测量左室舒张末期容积(LVEDV)、收缩末期容积(LVESV)、射血分数(LVEF),对比分析3D-HM与其他方法测量的差异性和相关性。结果ESV:3D-HM组较M型超声、Bi-plane、X-plane、2DQ、3DQA组ESV值偏高,差异具有显著统计学意义(P<0.01);EDV:3D-HM组较Bi-plane、X-plane、2DQ、3DQA组EDV值偏高,差异具有显著统计学意义(P<0.01),较M型超声组EDV值差异无统计学意义(P>0.05);EF:3D-HM组较M型超声、Bi-plane、2DQ组EF值偏低,差异具有显著统计学意义(P<0.01),较X-plane、3DQA组EF值差异无统计学意义(P>0.05)。相关性分析:ESV:3D-HM组与M型超声、Bi-plane、2DQ、X-plane、3DQA组ESV值呈正相关关系(P<0.05);EDV:3D-HM组与M型超声、Bi-plane、X-plane、2DQ、3DQA组EDV值呈正相关关系(P<0.05);EF:3D-HM组与M型超声、Bi-plane、2DQ、3DQA组EF值呈正相关(P<0.05),与X-plane组EF值无直线相关关系。结论3D-HM可以准确、快速量化左室容量及射血分数,在左心收缩功能评价中具有较高的临床价值。

Objective To investigate the application value of three-dimensional echocardiography Heart Model(3D-HM)in the assessment of left ventricular systolic function.Methods A total of 58 normal adults in our hospital from January 2018 to May 2019 were selected,including 24 males and 34 females.Left ventricular end-diastolic volume(LVEDV),end-systolic volume(LVESV)and ejection fraction(LVEF)were measured by conventional M-mode ultrasound,biplane Simpson method,two-dimensional cardiac function quantification(2DQ),three-dimensional automated cardiac function quantification(3DQA),and 3D-HM.The differences and correlations between 3D-HM and other methods were compared and analyzed.Results ESV:3D-HM group had higher ESV value than the M-mode ultrasound,Bi-plane,X-plane,2DQ,and 3DQA group,and the difference was statistically significant(P<0.01).The EDV:The EDV value in the 3D-HM group was higher than that in the Bi-plane,X-plane,2DQ,and 3DQA group,and the difference was statistically significant(P<0.01);and there was no significant difference in EDV value between the 3D-HM group and the M ultrasound group(P>0.05).EF:3D-HM group had lower EF value than M-mode ultrasound,Bi-plane,and 2DQ groups,and the difference was statistically significant(P<0.01).There was no significant difference in the EF value between 3D-HM group and X-plane,3DQA group(P>0.05).Correlation analysis:ESV:3D-HM group had positive correlation with ESV value of M-mode ultrasound,Bi-plane,2DQ,X-plane,and 3DQA group(P<0.05);EDV:3D-HM group was positively correlatedwith the EDV value of M-mode ultrasound,Bi-plane,X-plane,2DQ,and 3DQA group(P<0.05).EF:3D-HM group was positively correlated with the M-mode ultrasound,Bi-plane,2DQ,and 3DQA group(P<0.05),and there was no linear correlation in the EF values between the 3D-HM group and the X-plane group.Conclusion 3D-HM can accurately and quickly quantify left ventricular volume and ejection fraction,and has high clinical value in the evaluation of left ventricular systolic function.
