    • 摘要: Objective To explore the relationship between the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle in uremic patients with maintenance hemodialysis.Methods One hundred and thirty five uremic patients with maintenance hemodialysis (hemodialysis group) and 41 healthy subjects (control group) were enrolled in the study.The systolic tissue velocity,systolic tissue displacement,early distolic velocity and atrial systolic velocity of every segment of right ventricle were measured by echocardiography,and the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle were compared between two groups.The linear regression correlation between the parameters of myocardial motions of right ventricular walls and the indices of cardiac functions of left ventricle in patients of hemodialysis group was analyzed.Results The parameters of myocardial motions of right ventricular wall and the indices of cardiac functions of left ventricle in the patients of hemodialysis group were lower than those in control group (all P<0.05).The systolic velocity of basal segment of lateral wall (LVbs) was correlated with left ventricular cardiac output (LVCO)in hemodialysis group (r =0.31,P<0.05) with a linear regression equation of Y=0.28X + 4.76.The systolic displacement of mid segment of inferior wall (IDms) was correlated with atrial velocity of mitral valve annulus (MVa) (r =0.25,P<0.05) with a linear regression equation of Y=0.37X + 10.02.Conclusion In the uremic patients with hemodialysis,the integral systolic and diastolic function of left ventricle can affect the myocardial motions of right ventricular wall;on the contrary,the right ventricular regional myocardial motions can reflect the left ventricular integral function.%目的 探讨维持性血液透析尿毒症患者右心室壁局部心肌运动参数与左心室功能指标的关系.方法 选取维持性血液透析的尿毒症患者135例(血液透析组)和体检的正常成人41例(正常对照组)为研究对象,均进行超声心动图检查,测定右心室前、下、侧壁的基底段、中段、心尖段心肌的收缩期组织速度和位移,以及舒张早、晚期组织速度.比较两组受检者右心室壁局部心肌运动参数与左心室功能指标,并分析血液透析组患者右心室壁心肌运动参数与左心室功能指标的相关性.结果 血液透析组患者大部分右心室壁心肌运动参数与左心室功能指标均低于正常对照组(均P<0.05).血液透析组患者侧壁基底段收缩期组织速度与左心室心输出量相关性较强(r=0.31,P<0.05),直线回归方程为Y=0.28X+ 4.76;下壁中段收缩期组织位移与二尖瓣环舒张晚期速度相关性较强(r=0.25,P<0.05),直线回归方程为Y=0.37X+ 10.02.结论 维持性血液透析尿毒症患者左心室整体收缩与舒张功能对右心室壁局部心肌运动有一定影响,同时右心室壁局部心肌运动可反映左心室整体心功能.

    • 摘要: The ultrasonic technology is applied more and more widely in the assessment of the left ventricular torsion , and it has both advantages and shortcomings .Tissue Doppler imaging ( TDI) can accurately evaluate the left ventricular twist , but it may lead to an underestimatation .The quantitative tissue velocity imaging ( QTVI) can be used to observe the left ventricular twist mo-tion directly and accurately , but it is limited to the qualitative research of the torsion .The speckle tracking imaging ( STI) is ac-curate and reproducible , but it need higher quality of the image .This review is about the research progress of various ultrasonic techniques assessing the left ventricular twist .%近年来,超声技术在左室扭转运动评估中的应用越来越广泛,其自身技术特性各有优势与缺陷。组织多普勒显像可准确评价左室扭转运动,但其可能对左室扭转运动低估。定量组织速度成像可简捷直观且准确地观察左室扭转运动,但局限于对扭转的定性研究。斑点追踪技术显像准确、重现性好,但对图像质量要求较高。本文拟对各种超声技术在左室扭转运动评估中的研究进展作一综述,以期有助于超声技术的合理选择和良好应用。

    • 摘要: 目的 采用组织多普勒显像(TDI)技术评价左室肥厚(LVH)患者二尖瓣环舒张中期心肌速度曲线的特点及临床价值.方法 采用常规多普勒对168例LVH患者进行检查,测定二尖瓣舒张早期血流速度峰值(E)、舒张中期血流峰值速度(L)和舒张晚期血流峰值速度(A峰);采用TDI技术测定二尖瓣环侧壁或间壁收缩期运动速度(Sa)、舒张早期二尖瓣环运动速度(Ea)、舒张中期二尖瓣环运动速度(La)和舒张晚期二尖瓣环运动速度(Aa).结果 168例LVH患者中,56例(33%)发现有La,而且测定部位多见于二尖瓣环侧壁;42例(25%)发现有舒张中期跨二尖瓣血流L,La的存在预示左室充盈压的增加,有进一步发生心力衰竭(HF)的危险性.而当L与La相关时,发生HF的危险性增加.结论 LVH患者中多数可探测到舒张中期心肌速度La曲线,尤其在瓣环侧更容易检测到,它的存在,特别是与跨二尖瓣舒张中期血流峰值速度相关时,预示有左室充盈压增加和发生HF事件的危险性.%Objective To explore the features and clinical effectiveness of application of TDI (Tissue Doppler Imaging) in evaluation of mid-diastolic mitral annular velocity curve in patients with LVH (Left Ventricular Hypertrophy). MethodsConventional Doppler imaging was performed in 168 LVH patients to measure the indexes of early-diastolic (E), mid-diastolic (L), late-diastolic (A) blood lfow velocities of mitral valves. While, TDI was applied to measure the systolic motion velocity (Sa) of the lateral or septal wall of mitral valve annulus as well as the early-diastolic (Ea), mid-diastolic (La), late-diastolic (Aa) mitral annular motion velocity.Results Among all the 168 patients with LVH, 56 cases(33%) were identified with La especially in the lateral wall of mitral valve annulus; whereas mid-diastolic trans-mitrial blood lfow L was found in 42 (25%) cases. La indicated the increase of left ventricular iflling pressure and the risks of further HF (Heart Failure). When La was associated with the L, the risks of HF would be increased further.Conclusion La was frequently observed in patients with LVH, especially at the lateral annulus. Its presence might predict the increase of left ventricular iflling pressure and potential risks for HF events, particularly when it was associated with mid-diastolic trans-mitral blood flow velocity.

    • 摘要: Prevalent in various kinds of heart diseases, ventricular mechanical dyssynchrony could be improved owing to cardiac resynchronization therapy.Tissue Doppler imaging, real-time three dimensional echocardiography,two-dimensional speckle tracking imaging and three-dimensional speckle tracking imaging are able to provide accurate evaluation of left ventricular synchronicity and predict response to cardiac resyn-chronization therapy.Due to its noninvasive measurements,convenient operation and low cost,echocardio-graphy is rapidly emerging as a significant tool to assess ventricular mechanical synchronicity .Partially taking place of the invasive procedure in catherization and expensive equipment of magnetic resonance imaging ,ech-ocardiography seems to be a promising method in the clinical settings , as it contributes to relieved pain of patients as well as reduced cost of the patients′family.%心室运动的机械不同步在各种类型的心脏病中很普遍,而心脏再同步化治疗可改善同步性。组织多普勒显像、实时三维超声心动图、二维斑点追踪显像和三维超声斑点追踪技术可准确检测左心室的同步性,预测心脏再同步化治疗的效果。超声心动图具有无创伤、操作简便、费用少等优点,是评价左心室机械同步性的主要方法,可部分取代创伤性的心血管造影检查及昂贵的磁共振检查,减少患者的痛苦、减轻患者家属的经济负担,有广阔的临床应用前景。
