Abstract

Background This study aimed to assess cortical gray matter growth and maturation in neonates with congenital heart disease (CHD).Methods Thirty-one (near) term neonates with severe CHD (8 univentricular heart malformation (UVH), 21 d-transposition of great arteries (d-TGA) and 2 aortic coarctation) underwent cerebral MRI before (postnatal-day 7) and after (postnatal-day 24) surgery. Eighteen controls with similar gestational age had one MRI (postnatal-day 23). Cortical gray matter volume (CGM), inner cortical surface (iCS), and median cortical thickness were extracted as measures of volumetric growth, and gyrification index (GI) as measure of maturation.Results Over a median of 18 d, CGM increased by 21%, iCS by 17%, thickness and GI both by 9%. Decreased postoperative CGM and iCS were seen for CHD compared to controls (P values < 0.01), however with similar thickness and GI. UVH showed lower postoperative iCS, thickness (P values < 0.05) and GI (P value < 0.01) than d-TGA and controls. Infants requiring preoperative balloon-atrioseptostomy (BAS, 61%) had reduced postoperative CGM, iCS, and GI (P values < 0.05).Conclusion Infants with severe CHD show reduced cortical volumes compared to controls with gyrification being delayed in UVH, but not in d-TGA. Infants requiring BAS show higher risk of impaired cortical volume and gyrification.

  • Reductions in brain volumetric growth, cortical folding, and microstructural white matter maturation are well recognized in this high-risk population.

    “Additionally, reductions in brain volumetric growth, cortical folding, and microstructural white matter maturation are well recognized in this high-risk population.7,8”

    From Perioperative neonatal brain injury is associated with worse school-age neurodevelopment in children with critical congenital heart disease (2018) · cites this paper as [8]

    The Postoperative Cortical Morphology Compared to Healthy Controls section reports lower cortical gray matter volume in the CHD infants, supporting a volumetric difference, though it does not establish reduced growth rates relative to controls. The same section reports similar gyrification indices, contrary to a general reduction in cortical folding in this cohort. The paper discusses white matter abnormalities but does not report a measurement of microstructural white matter maturation. (LLM, conf=0.89)

  • Delayed cortical development, manifesting as delayed cortical folding, cortical depth asymmetry and reduced cortical thickness, has been reported in CHD fetuses and neonates.

    “delayed cortical development has been reported in CHD fetuses and neonates; the manifestations include delayed cortical folding, cortical depth asymmetry and reduced cortical thickness (25, 33).”

    From Changes in Cortical Thickness Are Associated With Cognitive Ability in Postoperative School-Aged Children With Tetralogy of Fallot (2020) · cites this paper as [33]

    The Discussion reports delayed gyrification in neonates with univentricular heart malformations and cites earlier findings of immature cortices in fetuses with hypoplastic left heart syndrome. The Perinatal Risk Factors section reports lower cortical thickness in the univentricular group than in infants with d-TGA, but the Postoperative Cortical Morphology section finds similar thickness in CHD infants and healthy controls and no significant left-right differences in cortical parameters. The paper therefore does not support cortical depth asymmetry or a general reduction in cortical thickness in CHD fetuses and neonates. (LLM, conf=0.90)

    Experimental — accuracy not yet measured
  • Neonates with transposition of the great arteries show a degree of cortical folding comparable to healthy controls.

    “Neonates with TGA (n=21) show a comparable degree of cortical folding to healthy controls.39”
  • Less complex sulci are already seen in fetuses with hypoplastic left heart syndrome around 30 weeks' gestation, and cortical folding is diminished in neonates with single ventricle pathology.

    “Less complex sulci (delayed first appearance or reduced depth) can already be seen in fetuses with HLHS around 30 weeks' gestation, 38 and cortical folding is diminished in neonates with SVP.38,39,42”
  • In neonatal studies, white matter and cortical gray matter are comparably reduced in transposition of the great arteries and single ventricle pathology.

    “In neonatal studies, white matter and CGM are comparably reduced in TGA and SVP.34,39”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
