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 کاملechocardiographic assessment of left ventricular twisting and untwisting rate in normal subjects by tissue doppler and velocity vector imaging: comparison of two methods
conclusions results suggest that these methods cannot be interchanged, and vvi showed significantly lower lv peak twist, peak twisting rate and peak untwisting rate. however, when lv twist and lv twisting rates were normalized to lv length, values were comparable for both imaging techniques. results twist degree was significantly lower in the vvi group than in the tdi group (p = 0.008, r = 0.56...

متن کاملEvaluation of left ventricular function in obese children without hypertension by a tissue Doppler imaging study
Background The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Aims Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. Settings and Design The present crosssectional study investigates subclinical systolic and diastolic dysfunction...
