- W2353255924 abstract "Objective To observe the value of tissue motion tracking of mitral annular displacement(TMAD)method in the assessment of left ventricular systolic function in patients with congestive heart failure(CHF).Methods Forty patients with CHF and forty healthy subjects were enrolled in this study.Left ventricular end-diastolic dimension(LVEDd),left ventricular end-systolic volume(LVESV),left ventricular end-diastolic volume(LVEDV)and left ventricular ejection fraction(LVEF)were measured with two-dimensional echocardiography.The maximal displacement of the six points of mitral annulus(DS)was measured with TMAD,and the correlation between mean displacement and LVEF was analyzed.Results Compared with healthy subjects,the LVDd,LVESV and LVEDV increased significantly(P0.01),and the LVEF decreased significantly(P0.01)in the CHF group.The Ds of the six points of mitral annulus were significantly lower in the CHF than those in the health group(P0.01).Compared with healthy subjects,the displacement of the six points of mitral annulus decreased significantly(P0.01),and the time to peak systolic displacement increased significantly(P0.01)in the CHF group.TMAD correlated well with biplane EF in the normal group(r=0.853,P0.01)and also correlated with biplane EF in the CHF group(r=0.419,P0.05).Conclusion TMAD is a new technology to evaluate global LV systolic function." @default.
