Abstract

Objective Adverse neurodevelopmental sequelae are common in children with congenital heart defects. Tetralogy of Fallot is part of the clinical phenotype of many genetic syndromes. We evaluated the determinants of neurodevelopmental outcome in patients with tetralogy of Fallot.Methods We performed a subgroup analysis of children with tetralogy of Fallot undergoing complete repair before 6 months of age who were enrolled in a trial assessing apolipoprotein E genotype as a predictor of neurodevelopmental outcome. Assessment included genetic evaluation, neurologic examination, and the Bayley Scales of Infant Development-II, yielding the Mental Developmental Index and Psychomotor Developmental Index.Results Sixty children were tested at 1 year of age. A confirmed or suspected genetic syndrome was identified in 18.3%. The mean Mental Developmental Index was 89 +/- 13, and the mean Psychomotor Developmental Index was 81 +/- 17. Scores for the Mental Developmental Index (76 +/- 13 vs 92 +/- 11) and Psychomotor Developmental Index (63 +/- 13 vs 85 +/- 15) were significantly lower for patients with genetic syndromes. The presence of a genetic syndrome was a predictor of lower Mental Developmental Index and Psychomotor Developmental Index (P = .002 and P = .001). The presence of tetralogy of Fallot with pulmonary atresia and the apolipoprotein E epsilon2 allele were predictive of a lower Mental Developmental Index (P = .001 and P = .035). No other preoperative or operative variables were predictive of worse neurodevelopmental outcome.Conclusions At 1 year of age after repair of tetralogy of Fallot, most patients had neurodevelopmental scores within the normal range. Genetic syndromes and the apolipoprotein E epsilon2 allele were important risk factors for neurodevelopmental dysfunction and accounted for some interindividual differences in outcome.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Most TOF survivors had neurodevelopmental scores within the normal range 1 year after surgical repair.

    “most of TOF survivors had neurodevelopmental scores within the normal range 1 year after their surgical repair”

    From Neurodevelopmental Outcomes in Tetralogy of Fallot: A Systematic Review (2022) · cites this paper as [17]

    The Conclusions and Abstract state that most patients had normal neurodevelopmental scores at 1 year of age after TOF repair. The claim instead places the assessment 1 year after surgery; the One-year Neurodevelopmental Examination section specifies assessment at 12 months of age, not 12 months postoperatively. (LLM, conf=0.88)

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.
