Objective To characterize the systolic torsion in dilated cardiomyopathy (DCM) by velocity vector imaging(VVI).Methods Eighty-seven subjects were studied using VVI:27 patients with DCM and 60 healthy control subjects.Left ventricular short-axis acoustic images were acquired at base and apex levels.The rotation angle and rotation velocity of endocardium and epicardium were measured.Results LVEF of DCM group was significantly lower than that of control group ( P＜0.01).The basal and apical rotation angle, rotation velocity were significantly lower in DCM group.The endocardial and epicardial rotation angle, rotation velocity were also significantly lower in DCM group than those in control group (P＜0.01).Conclusions VVI is a rapid and noninvasive tool to quantitatively assess cardiac torsional deformation in DCM patients,which providing another useful modality for evaluating cardiac function.

Objective To investigate strain and strain rate of right ventricular(RV)based on twodimensional image by velocity vector imaging in normal subjects.Methods Thirty-two healthy adults were rolled in this study.Echocardiographic images in 4 chamber view were analyzed by conventional manual tracing for volumes and ejection fractions,which were also measured by velocity vector imaging.Myocardial velocity,strain rate,and strain were determined at the basal,mid,and apical segments of the RV free wall and ventricular septum by velocity vector imaging.Results RV ejection fractions obtained with manual tracing correlated strongly with the same indexes obtained by velocity vector imaging method in all subjects(r=0.91,P＜0.01).The strain and strain rate value of middle segment and basal segment in RV free wall were higher than those of apical segment.There were same trend in ventricular septal.The strain and strain rate of middle segment and basal segment in RV free wall were higher than those of homologous segments in ventricular septal,but the indexes of apical segment in free wail and septal had no difference.The strain and strain rate in RV were not correlated with age.Conclusions Velocity vector imaging could accurately and quantitatively assess the strain and strain rate of RV.
