Evaluation of left ventricular systolic and twist function in patients with heart transplantation using ultrasound speckle tracking imaging / 中华超声影像学杂志

ABSTRACT

Objective To investigate the feasibility of ultrasound speckle tracking imaging(STI)in assessing left ventricular(LV)systolic and twist function in patients with heart transplantation.Methods Nine patients with heart transplantation and 10 subjects with normal LV function were examined by GE Vivid 7 with a M3S probe.Eighteen regional peak systolic strain and displacement in longitudinal,radial,circumferential,and 18 regional degree of rotation were measured respectively.Results The segmental regional peak systolic strain and displacement were less than those in subjects with normal LV function(P ＜0.05),but segmental regional degree of rotation was more than that in subjeets with normal LV function (P＜0.05).Conclusions STI may provide a noninvasive,simple and quick tool for evaluation of left ventricular systolic and twist function in patients with heart transplantation.
