Children with Congenital Heart Disease Show Increased Behavioral Problems Compared to Healthy Peers: A Systematic Review and Meta-Analysis

Millions of children and adults are living with congenital heart disease (CHD). Their risk for behavioral problems has not been the subject of a meta-analysis. We performed a systematic review and meta-analysis of measures of behavioral problems in people born with CHD compared to peers without CHD. We searched Pubmed, CINAHL, Embase, PsycInfo, and the Cochrane Library from January 1, 1986 to November 15, 2021. We included studies that reported a measure of behavioral problems in patients with CHD in children and adults older than 3 years of age. We screened 26,343 search results, and 24 studies met inclusion criteria. The quality of evidence was generally low. Subjects with CHD had a small increase in internalizing problems [standardized mean difference (SMD): 0.198, p = 0.02] and total behavior problems (SMD: 0.287, p = 0.013), but no difference in externalizing behavioral problems. There was significant heterogeneity in all three domains of behavior problems analyzed, and it could not be explained by variables such as age, severity, assessor, or assessment tool. There are small increases in parent- and self-reported overall behavioral problems and internalizing problems in patients with CHD compared to healthy controls. Wide confidence intervals in the meta-analyses leave open the possibility that certain factors may increase the risk of behavioral problems in this group, and future studies with important attention paid to potential confounders may help identify risk factors.

Parent-child bonding and attachment during pregnancy and early childhood following congenital heart disease diagnosis

Diagnosis and treatment of congenital heart disease (CHD) can present challenges to the developing parent-child relationship due to periods of infant hospitalization and intensive medical care, parent-infant separations, child neurodevelopmental delay and feeding problems, and significant parent and child distress and trauma. Yet, the ways in which CHD may affect the parent-child relationship are not well-understood. We systematically reviewed the evidence on parental bonding, parent-child interaction, and child attachment following CHD diagnosis, according to a pre-registered protocol (CRD42019135687). Six electronic databases were searched for English-language studies comparing a cardiac sample (i.e., expectant parents or parents and their child aged 0-5 years with CHD) with a healthy comparison group on relational outcomes. Of 22 unique studies, most used parent-report measures (73%) and yielded mixed results for parental bonding and parent-child interaction quality. Observational results also varied, although most studies (4 of 6) found difficulties in parent-child interaction on one or more affective or behavioural domains (e.g., lower maternal sensitivity, lower infant responsiveness). Research on parental-fetal bonding, father-child relationships, and child attachment behaviour was lacking. Stronger evidence is needed to determine the nature, prevalence, and predictors of relational disruptions following CHD diagnosis, and to inform targeted screening, prevention, and early intervention programs for at-risk dyads.

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.

Postnatal Cardiac Autonomic Nervous Control in Pediatric Congenital Heart Disease

Congenital heart disease is the most common congenital defect. During childhood, survival is generally good but, in adulthood, late complications are not uncommon. Abnormal autonomic control in children with congenital heart disease may contribute considerably to the pathophysiology of these long term sequelae. This narrative review of 34 studies aims to summarize current knowledge on function of the autonomic nervous system in children with a congenital heart defect. Large scale studies that measure both branches of the nervous system for prolonged periods of time in well-defined patient cohorts in various phases of childhood and adolescence are currently lacking. Pending such studies, there is not yet a good grasp on the extent and direction of sympathetic and parasympathetic autonomic function in pediatric congenital heart disease. Longitudinal studies in homogenous patient groups linking autonomic nervous system function and clinical outcome are warranted.
