Triphasic mitral inflow velocity with mid-diastolic flow: the presence of mid-diastolic mitral annular velocity indicates advanced diastolic dysfunction.
Mitral inflow filling pattern usually consists of 2 forward flow velocities in sinus rhythm: early rapid filling (E) and late filling with atrial contraction (A). However, additional mid-diastolic flow velocity may be present resulting in triphasic mitral inflow filling pattern. When mitral inflow is triphasic, mitral annulus velocity recorded by tissue Doppler imaging (TDI) frequently demonstr...
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'-...
متن کاملEvaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملPredictors of mitral annulus early diastolic velocity: impact of long-axis function, ventricular filling pattern, and relaxation.
AIMS Although left ventricular (LV) relaxation is well recognized as a predictor of mitral annulus (MA) early diastolic (E') velocity, its significance relative to other predictors of E' is less well understood. METHODS AND RESULTS We assessed 40 healthy volunteers, 43 patients with acutely decompensated chronic systolic heart failure (HF), and 36 patients with hypertrophic obstructive cardio...
متن کاملPeak early diastolic mitral annulus velocity by tissue Doppler imaging adds independent and incremental prognostic value.
OBJECTIVES The aim of this study was to ascertain if left ventricular mitral annulus velocities measured by tissue Doppler imaging (TDI) are more powerful predictors of outcome compared with clinical data and standard Doppler-echocardiographic parameters. BACKGROUND Tissue Doppler imaging of basal or mitral annulus velocities provides rapid assessment of ventricular long axis function. But it...
