Sequence of changes in myocardial performance index in relation to aortic isthmus and ductus venosus Doppler in fetuses with early-onset intrauterine growth restriction

To explore the sequence of changes in myocardial performance index (MPI) and aortic isthmus (AoI) and ductus venosus (DV) flow in fetuses with early-onset intrauterine growth restriction (IUGR).MPI and AoI and DV pulsatility indices (PI) were evaluated every 1-7 days in a cohort of IUGR fetuses with abnormal umbilical artery Doppler PI (> 95(th) percentile) delivered before 34 weeks' gestation. The longitudinal changes were analyzed in the last...
