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 کاملRight and left ventricular adaptation to hypoxia: a tissue Doppler imaging study.
Hypoxia has been reported to alter left ventricular (LV) diastolic function, but associated changes in right ventricular (RV) systolic and diastolic function remain incompletely documented. We used echocardiography and tissue Doppler imaging to investigate the effects on RV and LV function of 90 min of hypoxic breathing (fraction of inspired O(2) of 0.12) compared with those of dobutamine to re...
متن کاملHaemodialysis: effects of acute decrease in preload on tissue Doppler imaging indices of systolic and diastolic function of the left and right ventricles.
AIMS Conventional echocardiographic (ECHO) parameters of left ventricular (LV) and right ventricular (RV) systolic and diastolic function have been shown to be load-dependent; however, the impact of preload reduction on tissue Doppler (TD) parameters of LV and RV function is incompletely understood. The aim of this study was to examine the effect of acute preload reduction by haemodialysis (HD)...
متن کاملassessment of right ventricular function by tissue doppler, strain and strain rate imaging in patients with left-sided valvular heart disease and pulmonary hypertension
background pulmonary artery hypertension is the presentation of various types of cardiovascular and systematic diseases. there are different kinds of noninvasive methods to determine right ventricular function, pulmonary artery pressure, and effect of pulmonary hypertension on right ventricular function. these methods include the tissue doppler imaging (tdi) of the tricuspid annulus and the lon...
