Abstract

BACKGROUND: Congenital heart disease in newborns is associated with global impairment in development. We characterized brain metabolism and microstructure, as measures of brain maturation, in newborns with congenital heart disease before they underwent heart surgery. METHODS: We studied 41 term newborns with congenital heart disease--29 who had transposition of the great arteries and 12 who had single-ventricle physiology--with the use of magnetic resonance imaging (MRI), magnetic resonance spectroscopy (MRS), and diffusion tensor imaging (DTI) before cardiac surgery. We calculated the ratio of N-acetylaspartate to choline (which increases with brain maturation), the ratio of lactate to choline (which decreases with maturation), average diffusivity (which decreases with maturation), and fractional anisotropy of white-matter tracts (which increases with maturation). We compared these findings with those in 16 control newborns of a similar gestational age. RESULTS: As compared with control newborns, those with congenital heart disease had a decrease of 10% in the ratio of N-acetylaspartate to choline (P=0.003), an increase of 28% in the ratio of lactate to choline (P=0.08), an increase of 4% in average diffusivity (P<0.001), and a decrease of 12% in white-matter fractional anisotropy (P<0.001). Preoperative brain injury, as seen on MRI, was not significantly associated with findings on MRS or DTI. White-matter injury was observed in 13 newborns with congenital heart disease (32%) and in no control newborns. CONCLUSIONS: Term newborns with congenital heart disease have widespread brain abnormalities before they undergo cardiac surgery. The imaging findings in such newborns are similar to those in premature newborns and may reflect abnormal brain development in utero.

  • 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 [7]

    The Results passage in our copy (indexed under Abstract; page not supplied) reports lower white-matter fractional anisotropy in newborns with congenital heart disease, supporting reduced microstructural white-matter maturation. The paper does not report reductions in brain volumetric growth or cortical folding in this population; a reference to cortical gyration concerns a separate study of premature newborns. (LLM, conf=0.87)

  • Fetuses with CHDs benefit from intra-uterine growth, including a possible beneficial effect of growth on brain maturation.

    “This association is likely due to the fact that fetuses with CHDs benefit from intra-uterine growth, including a possible beneficial effect of growth on brain maturation [28–30].”

    From Early Evaluation and the Effect of Socioeconomic Factors on Neurodevelopment in Infants with Tetralogy of Fallot. (2021) · cites this paper as [30]

    The paper describes brain maturation with advancing maturity (Introduction, page not available) and discusses brain development in utero in fetuses with congenital heart disease (Discussion, page not available). It does not show that intrauterine growth benefits these fetuses or improves their brain maturation; the Discussion instead reports evidence of impaired prenatal brain development. (LLM, conf=0.74)

    Experimental — accuracy not yet measured
  • A high prevalence of anatomic and functional neurologic abnormalities has been documented before surgery in newborns with congenital heart disease, and such abnormalities are associated with childhood developmental status.

    “Reports from a number of investigators have documented a high prevalence of anatomic and functional neurologic abnormalities prior to surgery in newborns with CHD [9-17], and an association of such abnormalities with childhood developmental status [11,13,18,19].”
  • Adverse neurodevelopmental outcomes in children with complex congenital heart disease are due not only to perioperative insult but also to inborn factors.

    “However, there is increasing evidence that adverse neurodevelopmental outcomes in children with complex CHD are due not only perioperative insult, but to inborn factors as well.”
  • Cerebral lactate is a marker of anaerobic metabolism in the newborn and fetus, has been found in up to 50% of preoperative infants with congenital heart disease, and is associated with adverse outcome in other high-risk infants.

    “Cerebral lactate, a marker of anaerobic metabolism in the newborn and fetus [38,39], has been found in up to 50% of preoperative infants with CHD [14,15] and is associated with adverse outcome in other high-risk infants [40].”

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.
