ABSTRACT
Objective To evaluate the effectiveness of spatio-temporal image correlation with M-mode display ( STIC-M ) in monitoring fetal left ventricular systolic function in fetuses with congenital heart disease(CHD) . Methods Five hundred and thirty-six normal fetuses and 34 fetuses with CHD( 29 without hydrops and 5 with hydrops) were involved in the study . Left ventricular fractional shortening ( LVFS) was measured using STIC-M . The data of normal fetuses was used to construct reference ranges of LVFS for assessment of fetuses with CHD . Results The LVFS of the normal fetuses [ range26 .8% - 42 .9% , mean( 34 .9 ± 4 .1) % ] was negatively correlated with gestational age ( r = - 0 .16 , P < 0 .001) . Compared with the normal controls ,LVFS was significantly decreased in CHD fetuses with hydrops ( P < 0 .001) . However ,there was no significant difference in LVFS between normal controls and CHD fetuses without hydrops ( P > 0 .05) . Conclusions STIC-M is a new method that can be used to measure LVFS to evaluate fetal ventricular systolic function . The fetal ventricular contractile function of CHD fetuses without hydrops may not be damaged or is in compensation stage . The fetuses with cardiac hydrops generally become lower .
