Synopsis

Fetuses with complex congenital heart disease (CHD, n=23) and healthy gestational age-matched controls (n=25) were investigated. Hemodynamics were assessed by Doppler examinations. Fetal brain MR images were segmented to get global and regional morphological measurements. Results showed that fetuses with CHD have abnormally higher umbilical artery pulsation index and smaller global and regional brain volumes as early as 20-30 weeks; however, thickness, mean curvature, and sulcal depth of different brain lobes showed no statistical difference from the healthy controls. These results add to growing evidence of antenatal brain abnormalities of the CHD fetuses during the second and early third trimesters.
