Webimaging (TDI)-derived early diastolic mitral annular velocity (E’) and color M-mode (CMM) imaging flow propagation velocity (Vp) have been reported to be less load-dependent methods to assess LV relaxation [8]. TDI in evaluating left ventricular diastolic function was investigated by comparing the TDI with blood flow doppler method in this ... WebThe TDI mitral annulus systolic velocity and the early diastolic mitral annular velocity (Em) were significantly lower in the non-survivors (all P < 0.001). The pseudonormal (PN) or restrictive filling pattern (RFP) was associated with cardiac mortality. The other parameters associated with cardiac mortality were LV ejection fraction, LV mass ... This has become a major echocardiographic tool for assessment of both systolic and diastolic ventricular function. However, as this is a spectral technique, it is important to realise that measurement of peak values is dependent on the width of the spectrum, which again is a function of gain setting.
