Prognostic Power of Mitral Annulus Indices of Left Ventricular Diastolic Function
L eft ventricular (LV) diastolic function (LVDF) is an important determinant of exercise tolerance in patients with normal and depressed ejection fraction (EF). Several studies have also shown that noninvasive Doppler measurements of LV relaxation and filling pressures are predictors of outcome in several patients with cardiovascular (CV) disorders, including patients with HFrEF, HFpEF, atrial ...
متن کاملMitral flow derived Doppler indices of left ventricular diastolic function.
AIMS Left ventricular diastolic dysfunction has been proposed as the basis of heart failure in patients with normal left ventricular systolic function. Doppler indices of mitral inflow have been widely used to diagnose this condition and have been shown to correlate well with increased left atrial pressure in patients with cardiovascular disease. We wanted to establish age-specific criteria for...
متن کاملAssessment of left ventricular diastolic function by early diastolic mitral annulus peak acceleration rate: experimental studies and clinical application.
We sought to examine the hemodynamic determinants and clinical application of the peak acceleration rate of early (Ea) diastolic velocity of the mitral annulus by tissue Doppler. Simultaneous left atrial and left ventricular (LV) catheterization and Doppler echocardiography were performed in 10 dogs. Preload was altered using volume infusion and caval occlusion, whereas myocardial lusitropic st...
متن کاملDoppler echocardiographic indices of left ventricular diastolic function
The influence of age on six Doppler echocardiographic indices of left ventricular diastolic function was assessed in 86 normal volunteers aged from 20 to 74 years (mean 36). Five of the six indices showed a linear relation with age. Duration of isovolumic relaxation and maximal late diastolic (atrial) flow velocity increased significantly with age (r = 0-34 and r = 0-69, respectively). Converse...
متن کاملClinical validity of measuring time difference between onset of mitral inflow and onset of early diastolic mitral annulus velocity in the evaluation of left ventricular diastolic function.
OBJECTIVES This study was performed to validate the clinical usefulness of measuring the time difference between onset of mitral inflow and onset of early diastolic mitral annulus velocity (T(E'-E)) for the evaluation of left ventricular (LV) diastolic function. BACKGROUND In recent studies, T(E'-E) correlated well with the time constant of LV pressure decay (tau), and the ratio of IVRT/T(E'-...
