Velocity vector imaging provided valuable information for

detection and follow-up of cardiac abnormalities in patients with end stage renal disease.
REFER TO THE PAGE 171-176 Concept of ventricular torsion has long history and valuable concepts were established for ventricular torsion contributing to left ventricular (LV) diastolic relaxation and early diastolic filling to generate rapid “suction” power during diastole. However, ventricular torsion had been recognized as only interesting research tools for clinicians because of hard to assess the ventricular torsion in vivo; only available method was tagging magnetic resonance image for a while. Recently interests for ventricular torsion Inhibitors,research,lifescience,medical increased after two Inhibitors,research,lifescience,medical dimensional (2D) speckle tracking methods has been introduced. Velocity vector imaging is also an equipped image GABA inhibitor drugs analysis technique and provides strain, strain rate and LV torsion. Basal and apical rotation curve is derived by simple offline analysis and ventricular torsion is automatically calculated by equipped software.1) Non-invasive, bed-side approach using transthoracic echocardiography can provide better information for change of ventricular torsion according to patient’s clinical situation. Easier assessment attributed to increase number of researches and clinical trials to apply

the ventricular torsion to clinical field to improve the understanding Inhibitors,research,lifescience,medical for myocardial mechanics. Further approaches to LV torsion were made as a clinical indicator for decision making and prognostic indicator. Various studies about ventricular torsion Inhibitors,research,lifescience,medical in recent studies have suggested clinical implication.2) To measure LV function accurately, many noninvasive echocardiographic parameters have been developed. LV ejection fraction (LVEF) is a good parameter for ventricular function and Inhibitors,research,lifescience,medical even though it has numerous limitations, still it is the best clinical indicator to evaluate the ventricular function in most of clinics. Doppler and tissue Doppler follows to

LVEF and then, strain is now suggested as a better marker to evaluate the ventricular function but still stands between clinician and researchers. To be used as a clinical indicator, predominant accuracy beyond other functional markers as well as easy approach and reproducibility for measurement. In observational cohort study, to prove higher accuracy of ventricular torsion aminophylline can be hard to be achieved; however can be suggested with multivariate statistical analysis or subgroup analysis. Ventricular torsion is as far as it goes with other ventricular functional parameters, especially ejection fraction,3) harder to discriminate its superiority as a clinical indicator especially in patients group with dramatic change of LVEF during observational periods. This study by Deng et al.4) investigated about the change of ventricular torsion before and after kidney transplantation.
