Abstract:
ObjectiveTo investigate the value of full-volume three-dimensional echocardiography (FV3DE) in evaluating left ventricular systolic function in normal pregnancy.MethodsFifty-five healthy pregnant women,including 18 cases in first trimester (first trimester group),18 cases in second trimester (second trimester group) and 19 cases in third trimester (third trimester group),and 20 healthy nonpregnant women(control group) were chosen.The hemodynamic indexes and left ventricular systolic function parameters were detected by FV3DE.ResultsThe imaging satisfactory rates of FV3DE of control group,first trimester group,second trimester group and third trimester group were 100.0％ (20/20),100.0％ (18/18),88.9％ (16/18) and 78.9％(15/19) respectively.Compared with control group,heart rates (HR) of first,second and third trimester groups were significandy quicker (P ＜ 0.05);total peripheral resistance (TPR)declined gradually (P ＜ 0.05);LVM,LVMI,LVEDV,LVSV and LVCO increased gradually (P ＜0.05) ; MAP,LVEF,PER of four groups had no significant differences (P＞ 0.05 ).LVCO in healthy pregnant women had negative correlation with TPR (P ＜0.01),and positive correlation with HR,LVM,LVMI,LVEDV,LVSV,LVEF and PER (P ＜0.01),PER had positive correlation with LVEF.ConclusionThe application of FV3DE has significant clinical value in early evaluation of left ventricular systolic function in normal pregnancy.
