Congenital heart disease in school-aged children: Cognition, education, and participation in leisure activities

School Performance and Learning Challenges in Children and Adolescents with Congenital Heart Disease

Children with congenital heart disease are at risk for neurocognitive and neurodevelopmental challenges, learning disabilities, and psychosocial difficulties. Our narrative review draws literature-based evidence for the effect of congenital heart disease on school performance. We conducted a literature review and extracted relevant articles from Google Scholar, Medline, and PubMed. Evidence showcases that school performance is impacted directly by congenital heart disease. This seems to be underlined by different factors inherent to congenital heart disease, like inattention, language difficulties, and decreased fine and gross motor skills. Moreover, the operative and postoperative periods present various physical challenges that can hinder development, ultimately affecting daily activities and quality of life. The consequent stressors in childhood can have long-lasting effects, leading to an increased prevalence of anxiety and depression affecting patients as they transition into adolescence and adulthood and placing significant social and emotional burdens on their direct environment. Children with congenital heart disease face both direct and indirect challenges related to their disease. These challenges are most likely to be the source of poor school performance and learning, as suggested by the literature. Close monitoring, early interventions, and multidisciplinary care are essential to address these vulnerabilities and improve educational outcomes in children with congenital heart disease.

Executive function profiles in survivors of neonatal critical illness - a latent profile analysis in school-aged children born very preterm or with complex congenital heart disease and in typically developing peers

Executive function (EF) impairments are prevalent in survivors of neonatal critical illness such as children born very preterm (VPT) or with complex congenital heart disease (cCHD). This paper aimed to describe EF profiles in school-aged children born VPT or with cCHD and in typically developing peers, to identify child-specific and family-environmental factors associated with these profiles and to explore links to everyday-life outcomes. Data from eight EF tests assessing working memory, inhibition, cognitive flexibility, switching, and planning in n = 529 children aged between 7 and 16 years was subjected into a latent profile analysis. Three EF profiles were identified: The "favorable" profile was defined by mean scores in the normal range (z-scores ≤ -0.5 below the norm; n = 263, 49.7%). The "at-risk" profile's mean scores were 0.5 to 1 SD below the norm (n = 236, 44.6%). The "impaired" profile's mean scores were >1 SD below the norm (n = 30, 5.8%). Children of the two clinical groups were more likely to fall into the at-risk or impaired profile. Irrespective of clinical group, lower socioeconomic status, slower processing speed and poorer fine motor skills were associated with a more impaired profile. In turn, falling into the at-risk or impaired profile was associated with a higher need for educational support, poorer everyday-life EFs and more behavioral problems. Children in the impaired profile reported lower psychosocial quality of life. This study provides evidence for an increased risk of survivors of neonatal critical illness to present with an impaired EF profile that translates into everyday-life difficulties. Long-term monitoring is needed to promote optimal outcome.

Physical, social, and emotional impact on patients with congenital heart disease undergoing cardiac catheterization

INTRODUCTION

The management of congenital heart disease (CHD) has evolved, improving patient outcomes; however, challenges persist for patients, emphasizing the importance of assessing health-related quality of life (HRQoL). The widely used Pediatric Quality of Life Inventory underscores the relevance of HRQoL assessment, especially in children subject to medical procedures.

OBJECTIVE

To evaluate HRQoL in children with congenital heart disease undergoing cardiac catheterization, analysing its association with clinical and sociodemographic variables in a tertiary care hospital.

MATERIALS AND METHODS

We conducted a cross-sectional study in paediatric patients aged 2-18 years undergoing haemodynamic procedures for congenital heart diseases. We used the Pediatric Quality of Life Inventory (PedsQL) to assess HRQoL. The statistical analysis included descriptive statistics, χ2 tests, Kruskal-Wallis tests and multivariate linear regression analysis with the aim of identifying factors associated with HRQoL.

RESULTS

The sample included 164 patients, among whom pulmonary atresia and patent ductus arteriosus were frequent diagnoses. Physical functioning and school functioning were significantly impaired, with median scores of 32.14 (IQR, 17.14-62.87) and 56 (IQR, 28-88), respectively. The results were more favourable for emotional functioning and social functioning, with median scores of 62 (IQR, 32-74) and 68 (IQR, 44-100), respectively. Single ventricle defects and pulmonary atresia were associated with lower quality of life scores in emotional functioning (P = .035) and physical functioning (P = .048), respectively.

CONCLUSION

This study highlights the current challenges in evaluating HRQoL for children with CHD. It identified significant associations between specific diagnoses and decreased HRQoL scores, emphasizing the need for comprehensive care strategies.

Exploring frailty: muscle strength, functional capacity, activities of daily living and cognition in adult congenital heart disease

PURPOSE

The study aimed to assess frailty in adults with congenital heart disease (ACHD) and to compare muscle strength, functional capacity, activities of daily living (ADL), and cognition between frail and non-frail ACHD patients.

MATERIALS AND METHODS

A cross-sectional study design was used. Sixty people with ACHD aged between 18 and 45 years were included. Frailty was determined according to the Fried criteria. Peripheral muscle strength was assessed with a digital dynamometer, functional capacity with the 6-min walk test (6MWT), ADL with the Glittre ADL test, and cognition with the Montreal Cognitive Assessment (MoCA) test.

RESULTS

Frailty was seen in 38.33% (frail = 23 and non-frail = 37) of the participants. In the frail patients, dominant knee extensor strength (p = 0.002), shoulder abductor strength (p = 0.005), 6MWT distance (p = 0.021), and MoCA score (p = 0.005) were significantly lower than those in the non-frail patients. Glittre ADL test (p = 0.002) was significantly higher in the frail patients.

CONCLUSIONS

Muscle strength, functional capacity, ADL, functional mobility, and cognition were lower in the frail participants with ACHD. Early assessment of frailty in ACHD and planning individualized exercise training programs for frail individuals may be a strategy to reduce the impact of frailty on adverse clinical outcomes.

Physical Activity and Executive Functioning in Children and Adolescents with Congenital Heart Defects: A Scoping Review

Children and adolescents (C&As) with congenital heart defects (CHDs) have decreased functional capacity and executive functioning (EF) due to brain abnormalities and decreased cerebral perfusion. Exercise may improve EF via increased cognitive demands and cerebral blood supply. The purpose of this review was to identify evidence describing the impact of physical activity (PA) interventions on EF in C&As with CHDs. The following databases were searched from 2000 to 2024: MEDLINE, EMBASE, CINAHL, Scopus, CENTRAL, and PsycInfo. The inclusion criteria consisted of participants aged from birth to 18 years with CHD, interventions related to PA, and EF as an outcome measure. Articles were excluded if adults were included, translation to English was impossible, and full access was unavailable. Of 613 initial articles, 3 were analyzed, with only 1 meeting all inclusion criteria. The included study found significant improvements in self-reported cognitive functioning and parent-reported social functioning after 12 weeks of aerobic exercise in children aged 10-15 years with CHDs. Common themes among the reviewed articles indicated that EF remains impaired throughout the lifespan, children have unique interventional and developmental needs, and research remains limited despite theoretical benefits. Further investigation of the effect of PA on EF in C&As with CHDs is needed.

The cumulative impact of clinical risk on brain networks and associations with executive function impairments in adolescents with congenital heart disease

Patients with congenital heart disease (CHD) demonstrate altered structural brain network connectivity. However, there is large variability between reported results and little information is available to identify those patients at highest risk for brain alterations. Thus, we aimed to investigate if network connectivity measures were associated with the individual patient's cumulative load of clinical risk factors and with family-environmental factors in a cohort of adolescents with CHD. Further, we investigated associations with executive function impairments. In 53 adolescents with CHD who underwent open-heart surgery during infancy, and 75 healthy controls, diffusion magnetic resonance imaging and neuropsychological assessment was conducted at a mean age of 13.2 ± 1.3 years. Structural connectomes were constructed using constrained spherical deconvolution tractography. Graph theory and network-based statistics were applied to investigate network connectivity measures. A cumulative clinical risk (CCR) score was built by summing up binary risk factors (neonatal, cardiac, neurologic) based on clinically relevant thresholds. The role of family-environmental factors (parental education, parental mental health, and family function) was investigated. An age-adjusted executive function summary score was built from nine neuropsychological tests. While network integration and segregation were preserved in adolescents with CHD, they showed lower edge strength in a dense subnetwork. A higher CCR score was associated with lower network segregation, edge strength, and executive function performance. Edge strength was particularly reduced in a subnetwork including inter-frontal and fronto-parietal-thalamic connections. There was no association with family-environmental factors. Poorer executive functioning was associated with lower network integration and segregation. We demonstrated evidence for alterations of network connectivity strength in adolescents with CHD - particularly in those patients who face a cumulative exposure to multiple clinical risk factors over time. Quantifying the cumulative load of risk early in life may help to better predict trajectories of brain development in order to identify and support the most vulnerable patients as early as possible.

Early educational attainment in children with major congenital anomaly in the UK

OBJECTIVE

To describe early educational attainment and special educational needs (SEN) provision in children with major congenital anomaly (CA) compared with peers.

DESIGN

Analysis of educational data linked to the ongoing Born in Bradford cohort study. Confounders were identified via causal inference methods and multivariable logistic regression performed.

SETTING

Children born in Bradford Royal Infirmary (BRI), West Yorkshire.

PATIENTS

All women planning to give birth at BRI and attending antenatal clinic from March 2007 to December 2010 were eligible. 12 453 women with 13 776 pregnancies (>80% of those attending) were recruited. Records of 555 children with major CA and 11 188 without were linked to primary education records.

OUTCOMES

Key Stage 1 (KS1) attainment at age 6-7 years in Maths, Reading, Writing and Science. SEN provision from age 4 to 7 years.

RESULTS

41% of children with major CA received SEN provision (compared with 14% without), and 48% performed below expected standards in at least one KS1 domain (compared with 29% without). The adjusted odds of children with CA receiving SEN provision and failing to achieve the expected standard at KS1 were, respectively, 4.30 (95% CI 3.49 to 5.31) and 3.06 (95% CI 2.47 to 3.79) times greater than their peers. Those with genetic, heart, neurological, urinary, gastrointestinal and limb anomalies had significantly poorer academic achievement.

CONCLUSIONS

These novel results demonstrate that poor educational attainment extends to children with urinary, limb and gastrointestinal CAs. We demonstrate the need for collaboration between health and education services to assess and support children with major CA, so every CA survivor can maximise their potential.

Cognitive Functioning and Psychosocial Outcomes in Adults with Complex Congenital Heart Disease: A Cross-sectional Pilot Study

Adults with complex congenital heart disease (CHD) are at risk for cognitive dysfunction. However, associations between cognitive dysfunction and psychosocial outcomes are poorly defined. Between June and November 2022, we prospectively recruited 39 adults with complex CHD who completed a computerized cognitive assessment (Cogstate) and validated psychosocial scales measuring psychological distress, health-related quality of life (HRQOL), and resilience. Participants had a mean age of 36.4 ± 11.2 years. Over half (62%) were women, most (79%) had complex biventricular CHD, and 21% had Fontan physiology. Prevalence of cognitive dysfunction was greatest in the domains of attention (29%), working memory (25%), and psychomotor speed (21%). Adjusting for age and sex, Pearson partial correlations between Cogstate z-scores and self-reported cognitive problems were small. Participants who lived in the most disadvantaged areas and those with a below-average annual household income had lower global cognitive z-scores (p = 0.02 and p = 0.03, respectively). Two-thirds (64%) reported elevated symptoms of depression, anxiety, and/or stress. Small correlations were observed between psychological distress and cognitive performance. Greater resilience was associated with lower psychological distress (r ≥ -0.5, p < 0.001) and higher HRQOL (r = 0.33, p = 0.02). Our findings demonstrate that adults with complex CHD have a high risk of cognitive dysfunction, though may not recognize or report their cognitive challenges. Lower socioeconomic status may be an indicator for those at risk of poorer cognitive functioning. Psychological distress is common though may not be a strong correlate of performance-based cognitive functioning. Formal cognitive evaluation in this patient population is essential. Optimizing resilience may be a protective strategy to minimize psychological distress and bolster HRQOL.

Patterns of WISC-V Performance in Children with Congenital Heart Disease

Congenital heart disease (CHD) is one of the most common congenital birth defects. As surgical and interventional techniques have improved, the mortality has been greatly reduced and the focus has shifted to quality of life and long-term outcomes. The impact of CHD on development and cognition is becoming increasingly recognized. However, more research is needed to understand how children with CHD perform across various cognitive and intellectual domains. This study explored the performance of children with CHD on the newest version of the Wechsler Intelligence Scale for Children compared to normative controls. Children with CHD performed more poorly than normal controls across all indices and most subtests with large effect sizes. Additionally, we explored the patterns of impairment across indices and subtests, as well as the relationships between heard disease variables and WISC-V performance. Block design, Digit Span, and Similarities were the most commonly impaired scores in children with CHD, while Symbol Search, Picture Span, Figure Weights, and Vocabulary were least likely to be impaired.

Multimodal personalised executive function intervention (E-Fit) for school-aged children with complex congenital heart disease: protocol for a randomised controlled feasibility study

INTRODUCTION

Children with congenital heart disease (CHD) are at risk for executive functions (EF) impairments. To date, interventions have limited effects on EF in children and adolescents with complex CHD. Therefore, we developed a new multimodal and personalised EF intervention (E-Fit). This study aims to test the feasibility of this intervention called 'E-Fit' for children with complex CHD and EF impairments.

METHODS AND ANALYSIS

This is a single-centre, single-blinded, randomised controlled feasibility study exploring the E-Fit intervention. We aim to enrol 40 children with CHD aged 10-12 years who underwent infant cardiopulmonary bypass surgery and show clinically relevant EF impairments (T-score ≥60 on any Behaviour Rating Inventory for Executive Function questionnaire summary scale). The multimodal intervention was developed with focus groups and the Delphi method involving children and adolescents with CHD, their parents and teachers, and health professionals. The intervention is composed of three elements: computer-based EF training using CogniFit Inc 2022, performed three times a week at home; weekly EF remote strategy coaching and analogue games. The content of the computer and strategy training is personalised to the child's EF difficulties. The control group follows their daily routines as before and completes a diary about their everyday activities four times a week. Participants will be randomised in a 1:1 ratio. Feasibility is measured by the participants' and providers' ratings of the participants' adherence and exposure to the intervention, recruitment rates and the evaluation of the intended effects of the programme.

ETHICS AND DISSEMINATION

Local ethics committee approval was obtained for the study (BASEC-Nr: 2021-02413). Parents provide written informed consent. Key outputs from the trial will be disseminated through presentations at conferences, peer-reviewed publications and directly to participating families. Furthermore, these results will inform the decision whether to proceed to a randomised controlled trial to investigate effectiveness.

Mental health-related quality of life in mothers of children with surgically repaired congenital heart disease: a 13-year longitudinal study

AIMS

Having a child with congenital heart disease (CHD) can affect parental health-related quality of life (HR-QoL). We investigated the long-term trajectories of mental HRQoL (m-HRQoL) in mothers of children with CHD and examined risk factors for persistent low m-HRQoL.

METHODS

One hundred twenty-five mothers of children with CHD completed a standardized questionnaire on m-HRQoL (mental subscale SF-12) after the children's first open-heart surgery and subsequently when the children were 1, 4, 6, 10, and 13 years old. A z-score for m-HRQoL was calculated with national norms. Latent class growth analysis (LCGA) was used to identify subgroups of mothers with regards to their m-HRQoL trajectories over time. Regression analysis investigated predictors for chronically low m-HRQoL.

RESULTS

Compared to norms, mothers of children with CHD had significantly lower m-HRQoL immediately after open-heart surgery (β = -0.30 (CI-95: -0.44, -0.15)). Subsequently, m-HRQoL increased to a normal level (m-HRQoL compared to the norm from 1 to 13 years: β ranges between 0.05 and 0.27). LCGA revealed two distinct groups of m-HRQoL trajectories: A group with normal m-HRQoL (75% of mothers, means z-scores range between - 0.76 and 0.62) and a group with chronically low m-HRQoL (25% of mothers, mean z-scores range between -1.32 and -0.10). Chronically, low m-HRQoL was associated with poorer social support (OR = 3.39 (CI-95: 1.40, 8.49), p = 0.008) but not with parental education, migration background, number of open-heart surgeries, diagnosis of a univentricular CHD, or low IQ.

CONCLUSION

A quarter of mothers of children with CHD have chronically low m-HRQoL throughout their child's development, especially those mothers with poor social support. Further studies of family-oriented approaches are needed to identify and support these mothers and reinforce parental well-being.

Critical congenital heart disease beyond HLHS and TGA: neonatal brain injury and early neurodevelopment

BACKGROUND

Characterization of brain injury and neurodevelopmental (ND) outcomes in critical congenital heart disease (cCHD) has primarily focused on hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA). This study reports brain injury and ND outcomes among patients with heterogeneous cCHD diagnoses beyond HLHS and TGA.

METHODS

This prospective cohort study included infants with HLHS, TGA, or heterogenous "Other cCHD" including left- or right-sided obstructive lesions, anomalous pulmonary venous return, and truncus arteriosus. Brain injury on perioperative brain MRI and ND outcomes on the Bayley-II at 30 months were compared.

RESULTS

A total of 218 participants were included (HLHS = 60; TGA = 118; "Other cCHD" = 40, including 8 with genetic syndromes). Pre-operative (n = 209) and post-operative (n = 189) MRI showed similarly high brain injury rates across groups, regardless of cardiopulmonary bypass exposure. At 30 months, participants with "Other cCHD" had lower cognitive scores (p = 0.035) compared to those with HLHS and TGA, though worse ND outcome in this group was driven by those with genetic disorders.

CONCLUSIONS

Frequency of brain injury and neurodevelopmental delay among patients with "Other cCHD" is similar to those with HLHS or TGA. Patients with all cCHD lesions are at risk for impaired outcomes; developmental and genetic screening is indicated.

IMPACT

This study adds to literature on risk of brain injury in patients with critical congenital heart disease (cCHD) diagnoses other than hypoplastic left heart syndrome (HLHS) and transposition of the great arteries (TGA), a heterogenous cohort of patients that has often been excluded from imaging studies. Children with cCHD beyond HLHS and TGA have similarly high rates of acquired brain injury. The high rate of neurodevelopmental impairment in this heterogenous group of cCHD diagnoses beyond HLHS and TGA is primarily driven by patients with comorbid genetic syndromes such as 22q11.2 deletion syndrome.

Long-term neurodevelopmental outcome and serial cerebral magnetic resonance imaging assessment in Fontan patients at school age

OBJECTIVES

Children with univentricular congenital heart disease undergoing staged surgical palliation are at risk for impaired neurodevelopmental (ND) outcome. Little is known about the long-term effects on brain growth until school age.

METHODS

In a prospective two-centre study, consecutive patients undergoing stage I (Hybrid or Norwood) to stage III (Fontan procedure) were evaluated by 2 serial cerebral magnetic resonance imaging examinations, somatic growth and ND testing before Fontan procedure at 2 years of age (Bayley-III) and after Fontan at 6-8 years of age (Wechsler Intelligence Scale for Children-third edition). Magnetic resonance imaging findings were compared with 8 healthy controls. Medical and sociodemographic characteristics were documented and related to cerebral and ND findings.

RESULTS

We examined 33 children (16 female) at a mean age of 2.3 (0.35) and 6.8 (± 0.7) years. The mean Bayley-III cognitive scales were 99.1 (9.9), language scales 98.4 (11.9) and motor scales 98.5 (13.8) at the first examination. Follow-up at school age showed a mean total IQ of 86.7 (13.6). The rate of structural brain lesions increased from 39% at 2 years to 58% at school age. Bayley-III language scale (P = 0.021) and mean Wechsler Intelligence Scale for Children-third edition (P = 0.019) were lower in children with pathological MR findings. Total brain volume (P < 0.001), total grey matter volume (P = 0.002), deep grey matter volume (P = 0.001) and white matter volume (P < 0.001) were smaller in patients compared to age- and gender-matched healthy controls.

CONCLUSIONS

Smaller brain volumes and structural brain lesions in complex congenital heart defect patients at school age are associated with impaired ND outcome. For the evaluation of predictive surgical or clinical factors, larger multicentre studies are needed.

Exercise as therapy for neurodevelopmental and cognitive dysfunction in people with a Fontan circulation: A narrative review

People with a Fontan circulation are at risk of neurodevelopmental delay and disability, and cognitive dysfunction, that has significant implications for academic and occupational attainment, psychosocial functioning, and overall quality of life. Interventions for improving these outcomes are lacking. This review article discusses current intervention practices and explores the evidence supporting exercise as a potential intervention for improving cognitive functioning in people living with a Fontan circulation. Proposed pathophysiological mechanisms underpinning these associations are discussed in the context of Fontan physiology and avenues for future research are recommended.

Habilitation of Executive Functions in Pediatric Congenital Heart Disease Patients through LEGO®-Based Therapy: A Quasi-Experimental Study

Congenital heart disease is defined as an abnormality in the cardiocirculatory structure or function. Various studies have shown that patients with this condition may present cognitive deficits. To compensate for this, several therapeutic strategies have been developed, among them, the LEGO® Education sets, which use the pedagogic enginery to modify cognitive function by didactic material based on mechanics and robotics principles. Accordingly, the goal of this study was to evaluate the effect of cognitive habilitation by using LEGO®-based therapy in pediatric congenital heart disease patients. This was a quasi-experimental study; eligible patients were identified, and their general data were obtained. In the treatment group, an initial evaluation with the neuropsychological BANFE-2 test was applied; then, once a week, the interventions were performed, with a final test at the end of the interventions. In the control group, after the initial evaluation, a second appointment was scheduled for the final evaluation. Our results show that >50% of children presented cognitive impairment; nevertheless, there was an overall improvement in treatment patients, showing a significant increase in BANFE scores in areas related to executive functions. LEGO®-based therapy may be useful to improve cognitive abilities; however, future research should be performed to strengthen the data.

Mental sequelae of the COVID-19 pandemic in children with and without complex medical histories and their parents: well-being prior to the outbreak and at four time-points throughout 2020 and 2021

The objective of this study is to understand the long-term mental sequelae for families over the course of the COVID-19 pandemic by longitudinally investigating the well-being of children with and without complex medical histories and their parents. Well-being of 200 children (between 7 and 18 years of age; 73 typically developing, 46 born very preterm, 73 with complex congenital heart disease) and 175 of their parents was assessed prior to and during the first (April-May 2020), second (October-November 2020), third (April-May 2021), and fourth wave (October-November 2021) of the pandemic with standardized questionnaires. Linear mixed models were used to investigate longitudinal changes in child and parent well-being compared to before the pandemic. Social and COVID-19-specific determinants were investigated as predictors of impaired well-being. To illustrate clinical relevance, the proportion of children and parents scoring > 1 SD below normative mean/median was reported. Compared to before the pandemic, child proxy-reported well-being was lower during the first but not the second, third, and fourth waves. Child self-reported well-being was not lower during the pandemic compared to before. Parent well-being dropped during the first wave and remained low throughout the subsequent waves. Proxy-reported child and self-reported parent well-being was lower in families with sparse social support and poor family functioning. Parents of typically developing children reported lower well-being than parents of children born very preterm or with a complex congenital heart disease. In November 2021, 20% of children (both self- and proxy-report) and 24% of parents scored below the normal range compared to 11% (child self-report), 10% (child proxy-report), and 16% (parent self-report), respectively, before the pandemic. The pandemic continues to impact the well-being of parents of school-aged children with and without complex medical histories more than 1 year after its outbreak. Children's well-being was specifically affected during the first wave of the pandemic and has recovered thereafter. Families with sparse social support and poor family functioning are particularly at risk for compromised well-being and support should be provided to them.
