PMID 38819704WHAT IT FOUND
In 34 infants with congenital heart disease, 24-hour post-operative EEG severity and longer cross-clamp time were associated with lower language scores at 12-24 months.
Motor and cognitive outcomes were not linked to these EEG findings.
Key findings
01Severity of encephalopathy on the 24-hour post-operative EEG was significantly associated with lower language composite scores on the Bayley-III.
02Longer cross-clamp time during surgery was significantly associated with below-average language composite scores.
03Pre-operative and post-operative EEG background activity components were not associated with poor cognitive or motor outcomes.

What it does not show
The study had a very small sample size of 34 infants, which limits the reliability of the findings. Approximately 50% of the eligible infants were lost to follow-up and did not receive Bayley assessments, introducing potential selection bias. The study was retrospective, so it cannot prove causation. The wide spectrum of cardiac defects included prevented subgroup analysis by disease complexity. The Bayley-III assessment at 12-24 months has limited predictive value for later outcomes like IQ or behavioral issues in adolescence.
Declared interests
The study was funded by Cleveland Clinic Children’s Hospital. The authors declared no conflicts of interest.
The easy way to misread this
Do not assume that normal EEG background patterns rule out neurodevelopmental risk. In this study, all 34 infants had neurological abnormalities at follow-up, and EEG severity was only linked to language scores, not motor or cognitive outcomes.
