Echocardiographic 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 کاملLeft atrial mechanical functions in patients with anterior myocardial infarction: a velocity vector imaging-based study.
BACKGROUND The contribution of the left atrium (LA) to left ventricular (LV) function increases in myocardial infarction (MI). AIM To evaluate LA function by using volume measurements and a novel strain imaging method, namely velocity vector imaging (VVI), in patients with acute anterior MI. METHODS Twenty-four patients with previous anterior MI (aged 63.8 ± 4.2 years, 56% men) and 30 healt...
متن کاملChanges in left atrial deformation in hypertrophic cardiomyopathy: Evaluation by vector velocity imaging
OBJECTIVES Hypertrophic cardiomyopathy (HCM) represents a generalized myopathic process affecting both ventricular and atrial myocardium. We assessed the global and regional left atrial (LA) function and its relation to left ventricular (LV) mechanics and clinical status in patients with HCM using Vector Velocity Imaging (VVI). METHODS VVI of the LA and LV was acquired from apical four- and t...
متن کاملLeft atrial mechanical functions in chronic primary mitral regurgitation patients: a velocity vector imaging-based study
INTRODUCTION Assessment of the left atrium (LA) mechanical function provides further information on the level of cardiac compensation. We aimed to evaluate LA function using a strain imaging method: velocity vector imaging (VVI) in chronic primary mitral regurgitation (MR). MATERIAL AND METHODS We recruited 48 patients with chronic, isolated, moderate to severe MR (54.70 ±15.35 years and 56% ...
