Early Emotional, Behavioural and Social Development of Infants and Young Children with Congenital Heart Disease: A Systematic Review.

The experiences of diagnosis of congenital heart disease (CHD), cardiac surgery and hospitalisation(s) are distressing and represent a significant stressor for a child and family, which may impact psychosocial development. This systematic review provides a synthesis of psychosocial outcomes of infants and young children with congenital heart disease who had cardiac surgery early in life. Twenty-eight studies related to infant and young children's psychosocial development, specifically emotional, social and behavioural functioning were identified. Variability was related to methodological factors including differences in study design, varying measurement tools and heterogeneous samples. Despite these limitations, the majority of studies were of high quality. The most common finding was a high prevalence of low-severity emotional and behavioural dysregulation. Young children with severe CHD or comorbid conditions experienced greater impairment, with higher rates of externalising behaviour problems, although internalising behaviour problems were also evident. This review integrates findings from literature in the past 28 years on the psychosocial well-being of infants and young children with CHD and demonstrates a risk for emotional, social and behavioural development difficulty, and, importantly, that symptoms of psychosocial impairment are detectable very early in infancy. We advocate for assessment and monitoring of emotional and behavioural regulation and social development to be routinely conducted from infancy to enable prevention and early intervention.
