Noninvasive Assessment of Myocardial Mechanics of the Left Ventricle in Rabbits Using Velocity Vector Imaging
BACKGROUND Our study aimed to investigate the feasibility of velocity vector imaging (VVI) to analyze left ventricular (LV) myocardial mechanics in rabbits at basal state. MATERIAL AND METHODS The animals used in this study were 30 New Zealand white rabbits. All rabbits underwent routine echocardiography under VVI-mode at basal state. The 2-dimensional (2-D) echocardiography images acquired i...
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 کاملevaluation of left atrial two-dimensional strain in patients with systolic heart failure using velocity vector imaging
background two-dimensional (2d) strain is a new reproducible technique for assessing regional myocardial function; however, its application for evaluation of left atrium (la) function is less studied. objectives we sought to assess la function in heart failure patients using velocity vector imaging (vvi). patients and methods thirty five patients (mean age: 43.34 ± 18.1 years, 59.3% male) with ...
متن کاملassessment of inter and intra-atrial asynchrony in patients with systolic heart failure using velocity vector imaging
conclusions: left ventricular systolic heart failure, may result in inter and intra-atrial asynchrony even in clinically stable patients without significant pulmonary hypertension and diastolic dysfunction. results: in heart failure patients either inter or intra-atrial asynchrony were far more common in comparison with normal subjects (p=0.008 and p=0.007 respectively). patients and methods: t...
متن کاملVelocity and deformation imaging for the assessment of myocardial dysfunction.
Recent developments in echocardiographic imaging technology and processing enabled the quantification of myocardial motion and deformation in a clinical setting. Echocardiographic strain (-rate) imaging provides a relatively easy way to study myocardial deformation. However, although (local) deformation is clearly linked to cardiac (dys-) function, it is important to understand how this informa...
