['Fetuses with congenital heart disease (CHD) show evidence of abnormal brain development before birth, which is thought to contribute to adverse neurodevelopment during childhood. Our aim was to evaluate whether brain development in late pregnancy can be predicted by fetal brain Doppler, head biometry and the clinical form of CHD at the time of diagnosis.', "This was a prospective cohort study including 58 fetuses with CHD, diagnosed at 20-24\u2009weeks' gestation, and 58 normal control fetuses. At the time of diagnosis, we recorded fetal head circumference (HC), biparietal diameter, middle cerebral artery pulsatility index (MCA-PI), cerebroplacental ratio (CPR) and brain perfusion by fractional moving blood volume. We classified cases into one of two clinical types defined by the expected levels (high or low) of placental (well-oxygenated) blood perfusion, according to the anatomical defect. All fetuses underwent subsequent 3T-magnetic resonance imaging (MRI) at 36-38\u2009weeks' gestation.", 'Abnormal prenatal brain development was defined by a composite score including any of the following findings on MRI: total brain volume\u2009<\u2009\u200910(th) centile, parietoccipital or cingulate fissure depth\u2009<\u2009\u200910(th) centile or abnormal metabolic profile in the frontal lobe. Logistic regression analysis demonstrated that MCA-PI (odds ratio (OR), 12.7; P\u2009=\u20090.01), CPR (OR, 8.7; P\u2009=\u20090.02) and HC (OR, 6.2; P\u2009=\u20090.02) were independent predictors of abnormal neurodevelopment; however, the clinical type of CHD was not.'] Do mid-gestation brain Doppler and head biometry in fetuses with congenital heart disease predict abnormal brain development at birth?
