Assessment of foetal cardiac function by myocardial tissue doppler in foetal growth restriction

“…A similar study was undertaken by Naujorks et al where the results obtained were comparable to the present study. 6 A paradoxical finding in the present study which is not in accordance with the present literature is the finding of lower MPI' in IUGR babies in comparison to normal babies. All other studies show a higher value in IUGR babies explained by decreased stiffness of myocardial tissue in normal growth babies not seen in IUGR babies with increasing gestational age.…”

Assessment of Cardiac Dysfunction in the Intrauterine Growth-restricted Fetuses from Pre-eclamptic Mothers

“…12,18 In contrast with conventional ultrasound measurements, we observed differences in the TDI diastolic velocities parameters in the series of fetuses with IUGR included in this analysis as compared to values recorded in literature for fetuses from normal pregnancies. Our findings are similar to those reported by Naujorks et al, 3 which observed higher values of the E/A ratios at the interventricular septum in a group of IUGR fetuses with placental insufficiency as compared with appropriate for gestationalage fetuses from normal mothers. In contrast, other studies did not shown significant differences in TDI measurements in IUGR fetuses defined only by reduced weight or found similar TDI measurements in fetuses coming from healthy pregnancies and IUGR affected fetuses.…”

“…These findings are in line with those reported in other studies. 3,4,7 However, reduced or increased E/A ratios have also been reported. 10,11 The lack of significant differences in our study may be explained by the inclusion of only two cases with an umbilical artery reverse flow pattern as an indirect marker of an advanced fetal heart distress.…”

“…1 Fetal cardiovascular status can be assessed by both con ventional Doppler ultrasonography and myo cardial Tissue Doppler Imaging (TDI). 3 This former echo cardio graphic technique allows a quantitative measurement of motion and timing of myocardial events. 3 Considering the importance of assessing the fetal car diac function pattern, especially in the case of fragile IUGR fetuses, from the obstetrical management and neonatal prognosis perspective, diastolic dysfunction may be an early marker of fetal hypoxia.…”
