Toward a characterization of language development in children with congenital heart disease: A pilot study

Congenital heart diseases (CHDs) represent one of the most common types of congenital abnormalities. More than 90% of children with critical heart defects achieve adulthood due to improvements in medical and surgical treatments. Nonetheless, survivors are at risk for neurodevelopmental disorders that may lead also to language impairments. The current study analyzed the linguistic profiles of a group of school-aged children treated surgically for CHD.Fifteen Children with CHDs (7 girls and 8 boys; mean age = 9.31 with SD = 2.10), without intellectual disability (i.e., IQ>70), who underwent cardiac surgery on cardiopulmonary bypass (CPB), were administered a selection of tests from the language assessment tool BVL 4-12. Their performance was compared with that of 15 healthy children matched for age and gender. As a result, children with CHDs scored significantly lower than healthy peers on tasks tapping lexical and grammatical processing as well as the episodic buffer component of working memory. Interestingly, the two groups did not differ on tasks assessing their lexical repertoire and phonological discrimination abilities. These findings are discussed in light of current theories of cognitive development and functioning.
