组织速度显像结合实时三维超声心动图对右心衰竭患者右室功能的分析

The analysis of right ventricular function with tissue velocity imaging and real time three-dimension echocardiography

目的探讨组织速度显像(Tissue velocity imaging,TVI)结合实时三维超声心动图(real time threedimension echocardiography,RT-3DE)在右心衰竭患者右室功能评价中的应用价值。方法应用TVI结合RT-3DE技术,对新疆医科大学附属中医医院超声诊断为右室增大患者47例与正常对照组50例进行右室功能分析。根据有无右心衰竭临床表现将右室增大患者分为A组(右心衰竭)20例、B组(无右心衰竭)27例,分别测其心尖四腔心切面右室游离壁三尖瓣瓣环的组织速度Vs、Ve及Ve/Va值,实时三维测RVEDV、RVESV、RVSV及RVEF值。结果右室增大A组、B组患者RVEDV、RVESV均高于正常对照组(P<0.05),RVSV和RVEF及Vs、Ve、Ve/Va值均低于正常对照组(P<0.05)。结论 TVI结合实时三维超声可较敏感的评估右室地舒缩功能。

Objective We evaluated the right ventricular function with tissue velocity imaging （TVI）and real time three-dimension echocardiography （RT-3DE）.Methods 50 healthy control patients and 47 patients with right ven-tricular enlargement in our hospital were divided into group A （20 cases）and B （27 cases）according to the pres-ence or absence of right heart failure.All patients obtained both tissue velocity imaging of ultrasound examination and real time three-dimension echocardiography.The data were obtained from the velocity of right ventricular free wall′s three tricuspid valve ring on apical four chamber view,including Vs,Ve,Ve/Va ratios,EDV,ESV,SV and EF.Results ESV and EDV of patients in group A and B were higher than those of the control group （P ＆lt;0.05）.SV,EF,Vs,Ve and Ve/Va ratios of patients in group A and B were lower than those of the control group （P ＆lt;0.05）.Conclusion TVI combined with RT-3DE could assess more sensitively the right ventricular systolic and diastolic function.
