Abstract

Abstract : Aim: To report neurological examination findings at 5 to 12 months of age in infants with congenital heart disease (CHD) and to identify predictors of abnormal neurological examination. Method: This retrospective observational study included infants who required cardiac surgery at less than 3 months of age and underwent a standard neurological examination from a neurologist in the cardiac neurodevelopmental outpatient clinic between age 5 months and 12 months. Predictors for abnormal neurological examination (concerns on structured developmental history, demographic factors, medical history, and newborn neurodevelopmental assessment) were considered for multivariate regression. Results: The sample included 127 infants (mean age 7mo 2wks), who underwent first cardiac surgery at 7 days (4–49 interquartile range [IQR]) of age and were seen for a neurological examination in the cardiac neurodevelopmental clinic. Neurological abnormalities were common; 88% of infants had an abnormal neurological examination in at least one domain assessed. The most common abnormalities were abnormal axial (48%) and extremity (44%) tone, mostly hypotonia. Abnormal neurological examination was associated with concerns on the concurrent structured developmental history, genetic condition, extracardiac anomaly, longer length of stay, more than one cardiac surgery, ongoing early intervention services, and abnormalities on newborn neurodevelopmental assessment. Interpretation: Neurological examination abnormalities are common in infants with CHD after infant heart surgery, supporting the need for early and ongoing therapeutic developmental services and adherence to American Heart Association recommendations for developmental follow‐up for children with CHD. What this paper adds Neurological examination abnormalities are common in infants who undergo open‐heart surgery. Medical complications in infancy increase risk for neurological abnormalities. Family‐reported concerns on structured developmental history may predict abnormal neurological examination at 5 to 12 months of age. Abnormal newborn neurodevelopmental assessment may predict abnormal neurological examination at 5 to 12 months of age.
