As the number of CHD survivors have increased there is a growing focus on developmental morbidity.The objective of the current study is to compare symptoms of communication and social impairment in 18-month-old children with different severity of CHD with those of controls. Method We linked prospective data from the Norwegian Mother and Child Cohort Study, conducted by the Norwegian Institute of Public Health, with a nationwide medical CHD registry and identified 198 18-month-olds with CHD in a cohort of 47 692. Three groups of CHD were distinguished: mild/moderate (n = 122), severe (n = 54) and CHD with comorbidity (n = 22). Mothers reported on the child’s communication and social skills by completing items from the Ages and Stages Questionnaire as part of the Norwegian Mother and Child Cohort Study. Results Children aged 18 months old with CHD differed significantly from controls in levels of symptoms of communication impairment (P 0.0001) and social impairment (P 0.0001). The largest differences were found in children with CHD and comorbidity. Children with severe CHD also showed higher levels of both symptoms of communication and social impairment. Children with mild/moderate CHD showed a small difference only in symptoms of communication impairment. Conclusion Children with severe CHD and CHD with comorbidity show more symptoms of communication and social impairment compared with a large cohort at the age of 18 months. It is important to broaden the scope of inquiry to involve communication and social developmental domains. Introduction Every year 0.5%–1% of all infants are born with a congenital heart defect (CHD) (Hoffman & Kaplan 2002) making CHD the most common congenital malformations. With improved survival in the current era, it has become increasingly evident that neurological and developmental abnormalities compromise the quality of life in many children with severe CHD (Hovels-Gurich et al. 2002; Landolt et al. 2008).
