Evaluation of left ventricular radial myocardial motion velocity gradient in assessment of regional myocardial function by omni-directional M-mode echocardiography / 中华超声影像学杂志

ABSTRACT

Objective To assess regional myocardial function by left ventricular radial myocardial motion velocity gradient(MVG) measured by omni-directional M-mode echocardiography(OME). Methods There were 32 patients with hypertrophic cardiomyopathy(HCM), 20 patients with hypertension of left ventricular hypertrophy(HLVH),and 36 healthy volunteers in the study, LEJ-2 mode OME was used to measure and calculate MVG of 16 segment on left ventricular short axes. Results In the control group,MVG on left ventricular short axes were found to be decreased progressively from base plane to apical plane. Compared with the control group,the left ventricular MVG were reduced in HCM group and HLVH group( P <0. 05). Conclusions The left ventricular MVG can correspond directly to regional thickened myocardial motion,and can be used to evaluate left ventricular myocardial function in patients with thickened myocardium.
