Assessment of left atrial-left ventricular-arterial coupling using 2-dimensional speckle tracking echocardiography.
by 2D-STE, and investigated the effect of cardiovascular risk factors on LA-LV-arterial coupling.1 In their multivariate linear regression analysis, peak early diastolic LV longitudinal strain rate (SR-LVe) and E/e’/S-LAs were independent predictors related to abdominal aortic stiffness in patients with cardiovascular risk factors. On the other hand, only age contributed to abdominal aortic sti...
متن کاملNew noninvasive method for assessment of left ventricular rotation: speckle tracking echocardiography.
BACKGROUND Left ventricular (LV) torsion is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of LV function. In the present study, we introduce and validate speckle tracking echocardiography (STE) as a method for assessment of LV rotation and torsion. METHODS AND RESULTS Apical and basal rotation by STE was measured from short-axis images by aut...
متن کاملRadial left ventricular dyssynchrony by speckle tracking in apical versus non apical right ventricular pacing- evidence of dyssynchrony on medium term follow up.
INTRODUCTION To study effects of various sites of right ventricular pacing lead implantation on left ventricular function by 2-dimensional (2D) speckle tracking for radial strain and LV dyssynchrony. METHODS This was retrospective prospective study. Fifteen patients each with right ventricular (RV) apical (RV apex and apical septum) and non-apical (mid septal and low right ventricular outflow...
متن کاملImpact of Phase Analysis of Gated SPECT to Assessment of Left Ventricular Mechanical Dyssynchrony in Diabetic Patients with Normal MPI
Objective: Diabetes mellitus is an important cause of heart failure deployment of left ventricular mechanical dyssynchrony. Nuclear cardiology phase analysis is an accurate, repeatable and reproducible modality for measurement LV dyssynchrony .The aim of study was assessment of phase analysis parameter including Standard deviation (SD) and band width (BW) in diabetic patient with normal MPI com...
متن کاملImpact of loading condition on the 2D speckle tracking-derived left ventricular dyssynchrony index in nonischemic dilated cardiomyopathy.
BACKGROUND The effects of left ventricular (LV) loading conditions on LV dyssynchrony have not been elucidated. We modified LV loading conditions to reveal their effects on echocardiography-derived LV dyssynchrony index (LVdys) in patients with documented nonischemic dilated cardiomyopathy. METHODS AND RESULTS Thirty-seven patients were consecutively enrolled. After baseline measurements, pne...
