Background: This study aimed to investigate fetal cardiac functions by spectral tissue Doppler imaging (s-TDI) in pregnancies complicated with late-onset fetal growth restriction (LO-FGR) and small-for-gestational age (SGA). Methods: Forty pregnancies complicated with late-onset FCR and 40 pregnancies complicated with SGA between the 34th and 37th weeks of gestation were enrolled in this study. Forty gestational age-matched pregnant women with no obstetrics complication were randomly selected as a control group. Small fetuses were classified as fetal growth restriction or SGA according to estimated fetal weight (EFW), umbilical artery pulsatility index (PI), cerebroplacental ratio (CPR) and uterine artery PI. s-TDI measurements were obtained at the right atrioventricular valve annulus. Results: SGA and LO-FGR fetuses had significantly lower A' and S' values, and higher E'/A' ratio than the control group (P < 0.001). In comparison to controls, significantly prolonged isovolumetric contraction time (ICT') and isovolumetric relaxation time (IRT') and, significantly shortened ejection time (ET') were observed in fetuses with SGA and LO-FGR. Increased myocardial performance index (MPI') values were also found in fetuses with SGA and LO-FGR compared to controls. Conclusion: The signs of cardiac dysfunction were observed both in fetuses with SGA and LO-FGR. The fetal cardiac function assessment with s-TDI could be a valuable method in the diagnosis of true growth restricted fetuses and in the management of these fetuses.
