Abstract

Background Neurodevelopmental disabilities in children with congenital heart defects (CHDs) have been primarily attributed to intraoperative events without consideration of preoperative and postoperative factors.Objective To describe the preoperative and postoperative neurodevelopmental status of newborns and infants with CHDs.Study design One hundred thirty-one children (56 newborns and 75 infants) were evaluated before and after surgery by using standardized neurobehavioral (newborn) and motor assessments (infant) and neurologic examinations.Results In newborns, neurobehavioral abnormalities were documented in >50% before surgery, with abnormalities persisting in most after surgery. In infants, neurodevelopmental abnormalities were observed in 38% before surgery. There was a significant association between preoperative and postoperative neurodevelopmental status, with status remaining unchanged in most. Newborns with acyanotic heart lesions were more likely to demonstrate neurologic compromise than those with cyanotic defects. For infants, arterial oxygen saturations <85% were significantly associated with an abnormality. There was a trend for a longer circulatory arrest time to be associated with greater risk for neurologic sequelae in newborns, whereas prolonged cardiopulmonary bypass was an important risk factor for infants.Conclusions Neurodevelopmental abnormalities are common in young infants with CHDs and are often present before open heart surgery. These developmental concerns are clinically underappreciated. Early systematic developmental screening may be warranted in this population of interest.

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.
