Tissue Doppler imaging as a long-term prognostic index in left ventricular systolic dysfunction.
BACKGROUND Tissue Doppler parameters correlate with left ventricular (LV) filling pressure and can be useful as prognostic indexes for patients with heart failure. OBJECTIVE Determine whether tissue Doppler parameters can predict events during long term follow-up of outpatients with LV systolic dysfunction. METHODS Retrospective study with 73 patients (aged 60.9+/-12.1 years) who underwent ...
متن کاملEchocardiographic Assessment of Left Ventricle Torsion by Tissue Doppler and Velocity Vector Imaging
Introduction Left ventricular (LV) twist is believed to store potential energy and plays an important role in generating diastolic suction. Recent advances in echocardiography techniques have allowed quantification of LV twist. The aim of the present study was to compare LV twist and torsion in healthy human subjects determined by velocity vector imaging (VVI) and tissue Doppler imaging (TDI) a...
متن کاملdoppler tissue imaging: a non-invasive technique for estimation of left ventricular end diastolic pressure in severe mitral regurgitation
background: conventional doppler measurements, including mitral inflow and pulmonary venous flow, are used to estimate left ventricular end diastolic pressure (lvedp). however, these parameters have limitations in predicting lvedp among patients with mitral regurgitation. this study sought to establish whether the correlation between measurements derived from tissue doppler echocardiography and...

متن کاملEvaluation of left ventricular function in obese children without hypertension by a tissue Doppler imaging study
Background The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Aims Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. Settings and Design The present crosssectional study investigates subclinical systolic and diastolic dysfunction...
