Time-course changes in left ventricular myocardial deformation in STZ-induced rabbits on velocity vector imaging
OBJECTIVES To clarify the time-course changes in left ventricular myocardial deformation using velocity vector imaging and to provide insights into our understanding of the cardiac pathophysiology in diabetes mellitus. METHODS Thirty New Zealand white rabbits were randomly divided into either the control group (n = 10) or the diabetes mellitus (DM) group (induced with STZ, n = 20). For the my...
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 کاملNoninvasive 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 کاملTime course changes of oxidative stress and inflammation in hyperoxia-induced acute lung injury in rats
Objective(s):Therapies with high levels of oxygen are commonly used in the management of critical care. However, prolonged exposure to hyperoxia can cause acute lung injury. Although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (HALI). Materials ...
