Fetal and neonatal conventional and spectral tissue Doppler and two\u2010dimensional speckle tracking echocardiography were performed a few days before and within hours after birth.

The poorest perinatal outcomes occurred in FGR fetuses with the most impaired cardiac functional indices. When compared with normally grown neonates, FGR neonates showed persistent alteration in cardiac parameters (LV\u2010SI, 0.53 <jats:italic>vs<\/jats:italic> 0.50; RV\u2010SI, 0.54 <jats:italic>vs<\/jats:italic> 0.44; LV torsion, 1.1\u2009\u00b0\/cm <jats:italic>vs<\/jats:italic> 1.4\u2009\u00b0\/cm; LV myocardial performance index (MPI\u2032), 0.52 <jats:italic>vs<\/jats:italic> 0.42; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.01 for all). Paired comparison of fetal <jats:italic>vs<\/jats:italic> neonatal cardiac indices in FGR demonstrated that birth was associated with a significant improvement in some, but not all, cardiac indices (RV\u2010SI, 0.60 <jats:italic>vs<\/jats:italic> 0.54; RV\u2010MPI\u2032, 0.49 <jats:italic>vs<\/jats:italic> 0.39; <jats:italic>P<\/jats:italic>\u2009&lt;\u20090.001 for all).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Compared with normal pregnancies, FGR fetuses and neonates at term exhibit altered cardiac indices indicative of myocardial impairment that reflect adaptation to placental hypoxemia and alterations in hemodynamic load around the time of birth. Elucidating potential mechanisms that contribute to the alterations in perinatal cardiac adaptation in FGR could improve management and aid the development of better therapeutic strategies to reduce the risk of adverse pregnancy outcome.
