Abstract
OBJECTIVE It is often assumed, that adult patients with CHD (ACHD) have impairments regarding their cognitive function (CF) and health-related quality of life. In particular, it seems reasonable to assume that cyanosis may have a potential impact on CF as well as surgical or drug treatment into adulthood. This study assesses neuromental health aspects such as CF and health-related quality of life in ACHD patients. METHODS Seventy-eight ACHD patients (female n = 39 (50%); 34.1 ± 12.9 years; cyanotic CHD n = 49 (62.8%) with a cyanosis duration of 159.8 ± 196.2 month) who underwent open heart surgery as first intervention were asked to participate during routinely follow-up in 2018. Wechsler Intelligence Scale IV was used for CF and the Short Form 36 Health Survey to assess health-related quality of life. RESULTS Intelligence quotient measures showed significant differences comparing never cyanotic and with a cyanotic phase in verbal comprehension (p = 0.013). There was no association of CF with cyanosis duration, number of surgery or catheter, CHD severity, and time of first surgery. The group of early surgery showed significantly better results in physical function (p = 0.040) of health-related quality of life, and in comparison with their assigned reference, both groups showed significantly reduced results in all domains except in bodily pain and mental health. Full-Scale intelligence quotient correlates with physical function of health-related quality of life. CONCLUSIONS The results show normal CF in ACHD. Health-related quality of life was weak in comparison with the reference. There is a need to improve the well-being of our ACHD with structured programmes, including physical activity programmes. This growing ACHD population should be focused in order of their needs, medical ones on one hand and on the other hand psychosocial matters.

Implications of attention and executive functioning weaknesses in youth with Fontan circulation. Child Neuropsychol 2023; 29:1021-1040. [PMID: 36082702 DOI: 10.1080/09297049.2022.2120191] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/20/2022] [Accepted: 08/26/2022] [Indexed: 10/14/2022]
Abstract
Youth with Fontan circulation (Fontan) are at-risk for impairments in attention and executive functioning (EF) due to a confluence of genetic, prenatal, surgical, and medical risk factors. We sought to describe attention and EF in this population, measured via standardized performance-based tests and caregiver rating scales. We then examined how weaknesses in attention and EF were related to outcomes in other neurobehavioral domains, including adaptive behavior and academic achievement. Our sample included 93 youth with Fontan who were referred for neuropsychological evaluations as part of standard clinical care. The cohort as a whole measured between 0.18 to 0.99 standard deviations below normative means across domains of attention, EF, academic achievement, and intellectual ability. In addition, caregiver-reported concerns for attention, EF, anxiety, and depression were elevated, and approximately 0.35 to 0.85 standard deviations above normative means. Lastly, caregiver-reported adaptive behavior measured 0.93 to 1.24 standard deviations below normative values. Academic outcomes were differentially affected by demographic and attention/EF variables, while depression and caregiver-reported EF predicted adaptive behavior. Findings from this study underscore the importance of routine neuropsychological evaluation as part of comprehensive, multidisciplinary care for individuals with Fontan, with the goal of enhancing neurobehavioral and functional outcomes across the lifespan.

The Association Between Congenital Heart Disease and Autism Spectrum Disorder: A Systematic Review and Meta-Analysis. Pediatr Cardiol 2023; 44:1092-1107. [PMID: 36964783 DOI: 10.1007/s00246-023-03146-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/22/2022] [Accepted: 03/11/2023] [Indexed: 03/26/2023]
Abstract
Congenital heart disease (CHD) is linked to an increased incidence of neurodevelopmental impairments in young patients. Given the number of published studies on this topic, a synthesis of the literature is timely and needed. We performed a systematic review and meta-analysis of the medical literature to assess the evidence linking CHD to incidence of autism spectrum disorder (ASD). A systematic review of studies on CHD and ASD in PubMed, Cochrane and Institute for Scientific Information (ISI) from 1965 to May 2021 was conducted. Quantitative estimates of association between CHD and ASD were extracted from eligible studies for the meta-analysis. Pooled estimates were obtained using a random effect models fit by a generalised linear mixed model. We screened 2709 articles and 24 articles were included in this review. Among the 24 studies, there was a total of 348,771 subjects (12,114 CHD, 9829 ASD and 326,828 controls). Seven of 24 studies were eligible for the meta-analysis, which included information on a total of 250,611 subjects (3984 CHD, 9829 ASD, and 236,798 controls). The summary estimate indicated that having CHD is associated with almost double the odds of ASD compared with patients without CHD (OR 1.99, 95% CI 1.77-2.24, p < 0.01). Early developmental delay, perinatal factors, and genetics were potential risk factors and etiologies for the onset of ASD symptoms in CHD patients. Having CHD is associated with an increased risk of presenting with a diagnosis or symptoms suggestive of ASD.

The Genetics of Neurodevelopment in Congenital Heart Disease. Can J Cardiol 2023; 39:97-114.

Abstract
Congenital heart disease (CHD) is the most common birth anomaly, affecting almost 1% of infants. Neurodevelopmental delay is the most common extracardiac feature in people with CHD. Many factors may contribute to neurodevelopmental risk, including genetic factors, CHD physiology, and the prenatal/postnatal environment. Damaging variants are most highly enriched among individuals with extracardiac anomalies or neurodevelopmental delay in addition to CHD, indicating that genetic factors have an impact beyond cardiac tissues in people with CHD. Potential sources of genetic risk include large deletions or duplications that affect multiple genes, such as 22q11 deletion syndrome, single genes that alter both heart and brain development, such as CHD7, and common variants that affect neurodevelopmental resiliency, such as APOE. Increased use of genome-sequencing technologies in studies of neurodevelopmental outcomes in people with CHD will improve our ability to detect relevant genes and variants. Ultimately, such knowledge can lead to improved and more timely intervention of learning support for affected children.

A guide to prenatal counseling regarding neurodevelopment in congenital heart disease. Prenat Diagn 2022; 43:661-673. [PMID: 36575573 DOI: 10.1002/pd.6292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 12/07/2022] [Accepted: 12/17/2022] [Indexed: 12/29/2022]
Abstract
Advances in cardiac surgical techniques taking place over the past 50 years have resulted in the vast majority of children born with congenital cardiac malformations now surviving into adulthood. As the focus shifts from survival to the functional outcomes of our patients, it is increasingly being recognized that a significant proportion of patients undergoing infant cardiac repair experience adverse neurodevelopmental (ND) outcomes. The etiology of abnormal brain development in the setting of congenital heart disease is poorly understood, complex, and likely multifactorial. Furthermore, the efficacy of therapies available for the learning disabilities, attention deficit, and hyperactivity disorders and other ND deficits complicating congenital heart disease is currently uncertain. This situation presents a challenge for prenatal counseling as current antenatal testing does not usually provide prognostic information regarding the likely ND trajectories of individual patients. However, we believe it is important for parents to be informed about potential issues with child development when a new diagnosis of congenital heart disease is disclosed. Parents deserve a comprehensive and thoughtful approach to this subject, which conveys the uncertainties involved in predicting the severity of any developmental disorders encountered, while emphasizing the improvements in outcomes that have already been achieved in infants with congenital heart disease. A balanced approach to counseling should also discuss what local arrangements are in place for ND follow-up. This review presents an up-to-date overview of ND outcomes in patients with congenital heart disease, providing possible approaches to communicating this information to parents during prenatal counseling in a sensitive and accurate manner.

Abstract
IMPORTANCE Clinical studies of neurodevelopmental outcomes after anesthetic exposure have evaluated a range of outcomes with mixed results. OBJECTIVE To examine via meta-analyses the associations between exposure to general anesthesia and domain-specific neurodevelopmental outcomes in children. DATA SOURCES PubMed/MEDLINE, Embase, CINAHL, Web of Science and the Cochrane Library were searched from inception to August 31, 2021. STUDY SELECTION Inclusion criteria were exposures to procedures requiring general anesthesia at younger than 18 years and evaluation of long-term neurodevelopmental function after exposure. Studies lacking unexposed controls or focused on children with major underlying comorbidities were excluded. DATA EXTRACTION AND SYNTHESIS Extracted variables included effect size; hazard, risk, or odds ratio; number of exposures; procedure type; major comorbidities; age of exposure and assessment; presence of unexposed controls; and study design. Studies were independently reviewed by 2 coders, and review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Data were pooled using a random-effects model. MAIN OUTCOMES AND MEASURES The main outcomes were standardized mean differences (SMD) for scores in the neurodevelopmental domains of academics, behavioral problems, cognition, executive function, general development, language, motor function, nonverbal reasoning, social cognition, and hazard and risk of neurodevelopmental disorder diagnoses. RESULTS A total of 31 studies contributed data for meta-analysis. For each of the assessed neurodevelopmental domains, the numbers of children evaluated ranged from 571 to 63 315 exposed and 802 to 311 610 unexposed. Children with any exposure (single or multiple) had significantly worse behavioral problems scores, indicating more behavioral problems (SMD, -0.10; 95% CI, -0.18 to -0.02; P = .02), and worse scores in academics (SMD, -0.07; 95% CI -0.12 to -0.01; P = .02), cognition (SMD, -0.03; 95% CI, -0.05 to 0.00; P = .03), executive function (SMD, -0.20; 95% CI, -0.32 to -0.09; P < .001), general development (SMD, -0.08; 95% CI, -0.13 to -0.02; P = .01), language (SMD, -0.08; 95% CI, -0.14 to -0.02; P = .01), motor function (SMD, -0.11; 95% CI, -0.21 to -0.02; P = .02), and nonverbal reasoning (SMD, -0.15; 95% CI, -0.27 to -0.02; P = .02). Higher incidences of neurodevelopmental disorder diagnoses were also reported (hazard ratio, 1.19; 95% CI, 1.09 to 1.30; P < .001; risk ratio, 1.81; 95% CI, 1.25 to 2.61; P = .002). CONCLUSIONS AND RELEVANCE These findings support the hypothesis that associations between anesthetic exposure during childhood and subsequent neurodevelopmental deficits differ based on neurodevelopmental domain.

Abstract
The prognosis for infants born with complex heart disease improved dramatically with the introduction of the Fontan circulation 50 years ago. With today's carefully designed and staged operations to a Fontan circulation, life expectancy has increased and most children will survive into adult life. The Fontan circulation entails an unphysiological circulation with high risk for multiple organ system dysfunction. Neurodevelopmental disabilities with adverse psychosocial effects are prevalent. The Fontan circulation may eventually fail and necessitate heart transplantation. CONCLUSION: Fifty years development of the Fontan circulation to today's staged surgical procedures has improved survival but also revealed the burden of a high morbidity for a growing number of patients.

A Path FORWARD: Development of a Comprehensive Multidisciplinary Clinic to Create Health and Wellness for the Child and Adolescent with a Fontan Circulation. Pediatr Cardiol 2022; 43:1175-1192.

Abstract
Today, it is anticipated most individuals diagnosed with single-ventricle malformation will survive surgical reconstruction through a successful Fontan operation. As greater numbers of patients survive, so has the recognition that individuals with Fontan circulation face a variety of challenges. The goal of a normal quality and duration of life will not be reached by all. The hurdles fall into a variety of domains. From a cardiovascular perspective, the Fontan circulation is fundamentally flawed by its inherent nature of creating a state of chronically elevated venous pressure and congestion, accompanied by a relatively low cardiac output. Ventricular dysfunction, atrioventricular valve regurgitation, and arrhythmia may directly impact cardiac performance and can progress with time. Problems are not limited to the cardiovascular system. Fontan circulatory physiology impacts a multitude of biological processes and health parameters outside the heart. The lymphatic circulation is under strain manifesting as variable degrees of protein-rich lymph loss and immune system dysregulation. Organ system dysfunction develops through altered perfusion profiles. Liver fibrosis is ubiquitous, and a process of systemic fibrogenesis in response to circulatory stressors may affect other organs as well. Somatic growth and development can be delayed. Behavioral and mental health problems are common, presenting as clinically important levels of anxiety and depression. Most striking is the high variability in prevalence and magnitude of these complications within the population, indicating the likelihood of additional factors enhancing or mitigating their emergence. We propose that optimal care for the individual with single ventricle and a Fontan circulation is ideally offered in a comprehensive multidisciplinary manner, with attention to elements that are beyond cardiac management alone. In this report, we share the concepts, our experiences, and perspectives on development of a clinic model-the "Fontan rehabilitation, wellness and resilience development" or FORWARD program. We provide insights into the mechanics of our multidisciplinary model of care and the benefits offered serving our growing population of individuals with a Fontan circulation and their families.

Abstract
OBJECTIVE To characterize the neuropsychological outcome of children with congenital heart disease (CHD) at age 5 years; the stability of cognitive and language abilities across childhood; and to identify early neurodevelopmental markers of neuropsychological outcomes in these children. STUDY DESIGN Five-year-old children (n = 55) with complex CHD were assessed using standardized and comprehensive neuropsychological measures. Stability of language and cognitive performance was assessed by comparing standardized scores between ages 1, 2, and 5 years old. Association between 5-year-old skills and scores obtained in early childhood was studied to identify potential early markers of preschool performance. Receiver operating characteristic curves were used to evaluate the classification accuracy of Bayley Scales of Infant Development, Third Edition scales in identifying later impairments. RESULTS At age 5 years, our cohort obtained scores significantly below the norms on most developmental domains, with 35% to 65% of participants showing impaired short-term/working memory, attention, and preacademic skills. Developmental patterns measured between ages 1 and 5 years were different for cognitive and language domains, with a decline with age for cognitive functioning and stable results for expressive language. The Bayley Scales of Infant Development, Third Edition language scores at age 2 years provided a good predictive value in identifying children with impaired language at age 5 years. CONCLUSIONS In our cohort, we found a high prevalence of impairments affecting higher-order cognitive domains. Although language difficulties can be detected as early as 2 years of age, other neuropsychological impairments, such as attention and pre-academic skills, only appear later during development, which reinforces the need for long-term monitoring and systematic assessment before school entry.

Abstract
PURPOSE OF REVIEW This review aims to summarize and organize the current body of literature on this contemporary topic, alongside a more general discussion of neurodevelopmental complications of congenital heart disease. RECENT FINDINGS It is theorized that the causes of the neurodevelopment disabilities are multifactorial resulting from structural central nervous system abnormalities, haemodynamic alterations and/or biochemical changes. It is therefore imperative that all patients with single ventricle anatomy and physiology receive long-term neurologic and developmental assessments in addition to their cardiac monitoring. SUMMARY Advancements in surgical techniques and medical management have improved survivorship of these medically complex patients. Neurodevelopmental sequelae are one of the most common comorbidities affecting this patient population leading to long-term challenges in motor, language, social and cognitive skills.

Abstract
While survival for children with hypoplastic left heart syndrome (HLHS) has improved, compromised cardiac output and oxygen delivery persist, and children show cognitive deficits. Most research has assessed young children on broad cognitive indices; less is known about specific indices in older youth. In this pilot study, cognitive function and attention in youth ages 8 to 16 years with HLHS (n = 20) was assessed with the Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V) and NIH Toolbox Cognition Battery (NTCB); parents completed the Child Behavior Checklist. Children scored significantly lower than normative means on the WISC-V Full Scale IQ, Verbal Comprehension, Visual Spatial, Working Memory, and Processing Speed indices, and the NTCB Fluid Cognition Composite; effect sizes ranged from medium to large. Attention problems had a large significant effect. Child age corresponded to lower visual spatial scores. Findings highlight the importance of assessing multiple cognitive indices for targeted intervention and investigating age and disease factors as potential correlates in larger samples.

Abstract
Neurodevelopmental disabilities are the most common noncardiac conditions in patients with congenital heart disease (CHD). Executive function skills have been frequently observed to be decreased among children and adults with CHD compared with peers, but a neuroanatomical basis for the association is yet to be identified. In this study, we quantified sulcal pattern features from brain magnetic resonance imaging data obtained during adolescence among 41 participants with tetralogy of Fallot (ToF) and 49 control participants using a graph-based pattern analysis technique. Among patients with ToF, right-hemispheric sulcal pattern similarity to the control group was decreased (0.7514 vs. 0.7553, P = 0.01) and positively correlated with neuropsychological testing values including executive function (r = 0.48, P < 0.001). Together these findings suggest that sulcal pattern analysis may be a useful marker of neurodevelopmental risk in patients with CHD. Further studies may elucidate the mechanisms leading to different alterations in sulcal patterning.

Abstract
Infants born with congenital heart disease (CHD) are at increased risk of neurodevelopmental difficulties in childhood. The extent to which perioperative factors, cardiac physiology, brain injury severity, socioeconomic status, and home environment influence early neurodevelopment is not clear. Sixty-nine newborns with CHD were recruited from St Thomas' Hospital. Infants underwent presurgical magnetic resonance imaging on a 3-Tesla scanner situated on the neonatal unit. At 22 months, children completed the Bayley Scales of Infant and Toddler Development-3rd edition and parents completed the cognitively stimulating parenting scale to assess cognitive stimulation at home. Level of maternal education and total annual household income were also collected. Hospital records were reviewed to calculate days on the intensive care unit post-surgery, time on bypass during surgery, and days to corrective or definitive palliative surgical intervention. In the final analysis of 56 infants, higher scores on the cognitively stimulating parenting scale were associated with higher cognitive scores at age 22 months, correcting for gestational age at birth, sex, and maternal education. There were no relationships between outcome scores and clinical factors; socioeconomic status; or brain injury severity. Supporting parents to provide a stimulating home environment for children may promote cognitive development in this high-risk population.

Abstract
OBJECTIVE To investigate potential relationships between neuropsychologic functioning and cardiac, gastroenterologic/hepatologic, and pulmonary complications in the single ventricle heart disease (SVHD) post-Fontan population. STUDY DESIGN Following the initiation of a Fontan Multidisciplinary Clinic, patients with SVHD were evaluated systematically according to a clinical care pathway, and data from multiple subspecialty evaluations were collected prospectively from 2016 to 2019. Biomarkers of cardiology, pulmonary, and hepatology/gastroenterology functioning were abstracted, along with neuropsychologic testing results. Bivariate correlations and regression analyses examined cross-sectional relationships between physiologic predictors and neuropsychologic outcomes. RESULTS The sample included a cohort of 68 youth with SVHD age 3-19 years, after Fontan palliation. Sleep-disordered breathing was related to poorer visual-motor integration skills (r = -0.33; P < .05) and marginally related to poorer executive functioning (r = -0.33; P = .05). Lower arterial blood oxygen content was related to poorer executive functioning (r = .45; P < .05). Greater atrioventricular valve regurgitation was related to lower parent-rated adaptive functioning (ρ = -0.34; P < .01). These results were maintained in regression analyses controlling for history of stroke and/or seizures. CONCLUSIONS We demonstrated associations between neuropsychologic functioning and potentially modifiable aspects of physiologic functioning in a prospectively evaluated cohort of patients with SVHD with Fontan physiology. Our findings emphasize the importance of multidisciplinary screening and care after a Fontan procedure and suggest avenues for intervention that may improve patient outcomes and quality of life.

Abstract
OBJECTIVE Despite surgical palliation, children with hypoplastic left heart syndrome (HLHS) have compromised cardiac functioning and increased risk for cognitive deficits. We quantitatively reviewed the empirical data from this literature. METHODS The present meta-analysis included 13 studies reporting cognitive function for children with HLHS between the ages of 2 years and 6 months and 17 years that used standardized assessments of Full Scale IQ (FSIQ), Verbal IQ (VIQ), and Performance IQ (PIQ). Differences in cognitive function were assessed relative to normative data, and we examined sample mean age and publication year as moderators. RESULTS Large effects were found for FSIQ (g = -.87, 95% CI [-1.10, -.65], M = 86.88) and PIQ (g = -.89, 95% CI [-1.11, -.68], M = 86.56), and a medium effect was found for VIQ (g = -.61, 95% CI [-.84, -.38], M = 90.82). All models demonstrated significant heterogeneity. Meta-regression analyses of effect size via Hedges' g on child age revealed a significant effect on FSIQ (coefficient = -.07, 95% CI [-.12, -.01], p < .01, R2 = .40) indicating a loss of 1.1 FSIQ points across studies with each increased year of mean sample age. CONCLUSIONS Deficits in FSIQ may reflect chronic brain injury or failure to make expected gains as children age. This review highlights the importance of early intervention in this population, and the need for longitudinal studies analyzing more specific domains of cognitive function and potential moderators.

Abstract
Data from neurological and radiological research show an abnormal neurological development in patients treated for hypoplastic left heart syndrome. Thus, the aim of this study was to survey the quality of life scores in comparison with healthy children and children with other heart diseases (mild, moderate, and severe heart defects, heart defects in total). Children with hypoplastic left heart syndrome (aged 6.3-16.9 years) under compulsory education requirements, who were treated at the Children's Heart Center Linz between 1997 and 2009 (n = 74), were surveyed. Totally, 41 children and 44 parents were examined prospectively by psychologists according to Pediatric Quality of Life Inventory, a health-related quality of life measurement. The results of the self-assessments of health-related quality of life on a scale of 1-100 showed a wide range, from a minimum of 5.00 (social functioning) to a maximum of 100 (physical health-related summary scores, emotional functioning, school functioning), with a total score of 98.44. The parents' assessments (proxy) were quite similar, showing a range from 10 (social functioning) up to 100. Adolescent hypoplastic left heart syndrome patients rated themselves on the same level as healthy youths and youths with different heart diseases. The results show that patients with hypoplastic left heart syndrome aged 6-16 years can be successfully supported and assisted in their psychosocial development even if they show low varying physical and psychosocial parameters. The finding that adolescent hypoplastic left heart syndrome patients estimated themselves similar to healthy individuals suggests that they learnt to cope with a severe heart defect.

Abnormal Left-Hemispheric Sulcal Patterns Correlate with Neurodevelopmental Outcomes in Subjects with Single Ventricular Congenital Heart Disease. Cereb Cortex 2020; 30:476-487. [PMID: 31216004 PMCID: PMC7306172 DOI: 10.1093/cercor/bhz101] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2018] [Revised: 04/02/2019] [Accepted: 04/25/2019] [Indexed: 12/16/2022] Open
Abstract
Neurodevelopmental abnormalities are the most common noncardiac complications in patients with congenital heart disease (CHD). Prenatal brain abnormalities may be due to reduced oxygenation, genetic factors, or less commonly, teratogens. Understanding the contribution of these factors is essential to improve outcomes. Because primary sulcal patterns are prenatally determined and under strong genetic control, we hypothesized that they are influenced by genetic variants in CHD. In this study, we reveal significant alterations in sulcal patterns among subjects with single ventricle CHD (n = 115, 14.7 ± 2.9 years [mean ± standard deviation]) compared with controls (n = 45, 15.5 ± 2.4 years) using a graph-based pattern-analysis technique. Among patients with CHD, the left hemisphere demonstrated decreased sulcal pattern similarity to controls in the left temporal and parietal lobes, as well as the bilateral frontal lobes. Temporal and parietal lobes demonstrated an abnormally asymmetric left-right pattern of sulcal basin area in CHD subjects. Sulcal pattern similarity to control was positively correlated with working memory, processing speed, and executive function. Exome analysis identified damaging de novo variants only in CHD subjects with more atypical sulcal patterns. Together, these findings suggest that sulcal pattern analysis may be useful in characterizing genetically influenced, atypical early brain development and neurodevelopmental risk in subjects with CHD.

Abstract
BACKGROUND Norwood surgery has been available in Sweden since 1993. In this national cohort study, we analysed transplantation-free survival after Norwood surgery for hypoplastic left heart syndrome with aortic atresia. METHODS Patients were identified from the complete national cohort of live-born with hypoplastic left heart syndrome/aortic atresia 1993-2010. Analysis of survival after surgery was performed using Cox proportional hazards models for the total cohort and for birth period and gender separately. Thirty-day mortality and inter-stage mortality were analysed. Patients were followed until September 2016. RESULTS The 1993-2010 cohort consisted of 208 live-born infants. Norwood surgery was performed in 121/208 (58%). The overall transplantation-free survival was 61/121 (50%). The survival was higher in the late period (10-year survival 63%) than in the early period (10-year survival 40%) (p = 0.010) and lower for female (10-year survival 34%) than for male patients (10-year survival 59%) (p = 0.002). Inter-stage mortality between stages I and II decreased from 23 to 8% (p = 0.008). For male patients, low birthweight in relation to gestational age was a factor associated with poor outcome. CONCLUSION The survival after Norwood surgery for hypoplastic left heart syndrome/aortic atresia improved by era of surgery, mainly explained by improved survival between stages I and II. Female gender was a significant risk factor for death or transplantation. For male patients, there was an increased risk of death when birthweight was lower than expected in relation to gestational age.

Abstract
Background Management of patients with hypoplastic left heart syndrome has benefited from advancements in medical and surgical care. Outcomes have improved, although survival and long‐term functional and cognitive deficits remain a concern. Methods and Results This is a cohort study of all consecutive patients with hypoplastic left heart syndrome undergoing surgical palliation at a single center. We aimed to examine demographic and perioperative factors from each surgical stage for their association with survival and neurocognitive outcomes. A total of 117 consecutive patients from 1996 to 2010 underwent surgical palliation. Seventy patients (60%) survived to the Fontan stage and 68 patients (58%) survived to undergo neurocognitive assessment at a mean (SD) age of 56.6 months (6.4 months). Full‐scale, performance, and verbal intelligence quotient, as well as visual‐motor integration mean (SD) scores were 86.7 (16.1), 86.3 (15.8), 88.8 (17.2), and 83.2 (14.8), respectively. On multivariable analysis, older age at Fontan, sepsis peri‐Norwood, lowest arterial partial pressure of oxygen postbidirectional cavopulmonary anastomosis, and presence of neuromotor disability pre‐Fontan were strongly associated with lower scores for all intelligence quotient domains. Older age at Fontan and sepsis peri‐Norwood remained associated with lower scores for all intelligence quotient domains in a subgroup analysis excluding patients with disability pre‐Fontan or with chromosomal abnormalities. Conclusions Older age at Fontan and sepsis are among independent predictors of poor neurocognitive outcomes for patients with hypoplastic left heart syndrome. Further studies are required to identify the appropriate age range for Fontan completion, balancing a lower risk of acute and long‐term hemodynamic complications while optimizing long‐term neurocognitive outcomes.

Abstract
Neurodegeneration has been reported in young animals after exposure to all commonly used general anesthetic agents. The brain may be particularly vulnerable to anesthetic toxicity during peak synaptogenesis (in gestation and infancy). Human studies of long-term neurodevelopmental outcome following general anesthesia in early childhood report contradictory findings. This review assesses the strengths and deficiencies in human research methodologies to inform future studies. We identified 76 studies, published between 1990 and 2017, of long-term neurodevelopmental outcome following early childhood or in utero general anesthesia exposure: 49 retrospective, 9 ambidirectional, 17 prospective cohort studies, and 1 randomized controlled trial. Forty-nine studies were explicitly concerned with anesthetic-induced neurotoxicity. Full texts were appraised for methodological challenges and possible solutions. Major challenges identified included delineating effects of anesthesia from surgery, defining the timing and duration of exposure, selection of a surgical cohort and intervention, addressing multiple confounding life course factors, detecting modest neurotoxic effects with small sample sizes (median, 131 children; interquartile range, 50–372), selection of sensitive neurodevelopmental outcomes at appropriate ages for different developmental domains, insufficient length of follow-up (median age, 6 years; interquartile range, 2–12 years), and sample attrition. We discuss potential solutions to these challenges. Further adequately powered, multicenter, prospective randomized controlled trials of anesthetic-induced neurotoxicity in children are required. However, we believe that the inherent methodological challenges of studying anesthetic-induced neurotoxicity necessitate the parallel use of well-designed observational cohort studies.

Abstract
INTRODUCTION Congenital heart disease (CHD) is one of the most common causes of infant admission to pediatric intensive care and is associated with profound psychological stress for mothers, fathers and their infants. Intensive care unit admission represents an opportunity to offer evidence-based strategies to prevent or minimize severe psychological distress and promote secure bonding and attachment, alongside high-quality infant medical care. OBJECTIVES We aimed to identify, synthesize and critically appraise published evidence on the efficacy and cost-effectiveness of mental health interventions delivered in neonatal, pediatric or cardiac intensive care units for parents of infants with CHD. A secondary goal was to develop recommendations for advancing health policy, practice and research in the field. METHODS In accordance with a prospectively registered protocol (CRD42019114507), six electronic databases were systematically searched for studies reporting results of a controlled trial of a mental health intervention for parents of infants aged 0-12 months with a congenital anomaly requiring intensive care unit admission. To maximize generalizability of results, trials involving infants with any type of structural congenital anomaly requiring surgery were included. Outcomes included intervention type, process, efficacy, and cost-effectiveness. RESULTS Across all forms of congenital anomaly, only five trials met inclusion criteria (four in CHD, one in gastrointestinal malformation). All interventions engaged parents face-to-face, but each had a distinct therapeutic approach (parent-infant interaction and bonding, early pediatric palliative care, psycho-education, parenting skills training, and family-centered nursing). Four of the five trials demonstrated efficacy in reducing maternal anxiety, although the quality of evidence was low. Positive results were also found for maternal coping, mother-infant attachment, parenting confidence and satisfaction with clinical care, as well as infant mental (but not psychomotor) development at 6 months. Mixed results were found for maternal depression and infant feeding. No evidence of efficacy was found for improving parent, infant or family quality of life, physical health or length of infant hospital stay, and there were no data on cost-effectiveness. CONCLUSIONS Stronger evidence for the efficacy of mental health interventions to buffer the effects of intensive care unit admission for parents of infants with CHD is urgently needed. Robust, high-quality trials are lacking, despite the established need and demand, and health policies prioritizing parent mental health care in the context of early childhood adversity are needed.

Abstract
Background Prenatal diagnosis of single ventricle‐type congenital heart disease is associated with improved clinical courses. Prenatal counseling allows for optimal delivery preparations and opportunity for prenatal intervention. Expectant parents frequently ask what the likelihood of survival through staged palliation is and the factors that influence outcome. Our goal was specifically to quantify peri‐ and postnatal outcomes in this population. Methods and Results We identified all patients with a prenatal diagnosis of single ventricle‐type congenital heart disease presenting between July 2004 and December 2011 at our institution. Maternal data, fetal characteristics, and data from the postnatal clinical course were collected for each patient. Kaplan–Meier curves and multivariate analysis with logistic regression were used to evaluate variables associated with decreased transplant‐free survival. Five hundred two patients were identified, consisting of 381 (76%) right ventricle– and 121 left ventricle–dominant lesions. After prenatal diagnosis, 42 patients did not follow up at our center; 79 (16%) chose termination of pregnancy, and 11 had intrauterine demise with 370 (74%) surviving to birth. Twenty‐two (6%) underwent palliative care at birth. Among 348 surviving to birth with intention to treat, 234 (67%) survived to at least 6 months post‐Fontan palliation. Presence of fetal hydrops, right ventricle dominance, presence of extracardiac anomalies, and low birthweight were significantly associated with decreased transplant‐free survival. Conclusions In patients with a prenatal diagnosis of single ventricle‐type congenital heart disease and intention to treat, 67% survive transplant‐free to at least 6 months beyond Fontan operation. An additional 5% survive to 4 years of age without transplant or Fontan completion. Fetuses with right ventricle–dominant lesions, extracardiac anomalies, hydrops, or low birthweights have decreased transplant‐free survival.

Abstract
It has been 50 years since Francis Fontan pioneered the operation that today bears his name. Initially designed for patients with tricuspid atresia, this procedure is now offered for a vast array of congenital cardiac lesions when a circulation with 2 ventricles cannot be achieved. As a result of technical advances and improvements in patient selection and perioperative management, survival has steadily increased, and it is estimated that patients operated on today may hope for a 30-year survival of >80%. Up to 70 000 patients may be alive worldwide today with Fontan circulation, and this population is expected to double in the next 20 years. In the absence of a subpulmonary ventricle, Fontan circulation is characterized by chronically elevated systemic venous pressures and decreased cardiac output. The addition of this acquired abnormal circulation to innate abnormalities associated with single-ventricle congenital heart disease exposes these patients to a variety of complications. Circulatory failure, ventricular dysfunction, atrioventricular valve regurgitation, arrhythmia, protein-losing enteropathy, and plastic bronchitis are potential complications of the Fontan circulation. Abnormalities in body composition, bone structure, and growth have been detected. Liver fibrosis and renal dysfunction are common and may progress over time. Cognitive, neuropsychological, and behavioral deficits are highly prevalent. As a testimony to the success of the current strategy of care, the proportion of adults with Fontan circulation is increasing. Healthcare providers are ill-prepared to tackle these challenges, as well as specific needs such as contraception and pregnancy in female patients. The role of therapies such as cardiovascular drugs to prevent and treat complications, heart transplantation, and mechanical circulatory support remains undetermined. There is a clear need for consensus on how best to follow up patients with Fontan circulation and to treat their complications. This American Heart Association statement summarizes the current state of knowledge on the Fontan circulation and its consequences. A proposed surveillance testing toolkit provides recommendations for a range of acceptable approaches to follow-up care for the patient with Fontan circulation. Gaps in knowledge and areas for future focus of investigation are highlighted, with the objective of laying the groundwork for creating a normal quality and duration of life for these unique individuals.

Abstract
It is established that neurodevelopmental disability (NDD) is common in neonates undergoing complex surgery for congenital heart disease (CHD); however, the trajectory of disability over the lifetime of individuals with CHD is unknown. Several ‘big issues’ remain undetermined and further research is needed in order to optimise patient care and service delivery, to assess the efficacy of intervention strategies and to promote best outcomes in individuals of all ages with CHD. This review article discusses ‘gaps’ in our knowledge of NDD in CHD and proposes future directions.

Abstract
Worldwide, more than 400,000 infants are born each year with complex congenital heart disease (CCHD) requiring surgical intervention within the first months of life. Although improvements in perioperative care have resulted in increased rates of survival, more than half of infants with CCHD have neurodevelopmental impairments affecting subsequent educational achievements, job opportunities, and mental health. Brain maturity and impaired outcomes in infants with CCHD are similar to those of prematurely born infants. Developmentally supportive care, including foundational application of kangaroo care (KC), improves neurodevelopment in premature infants. Provision of developmentally supportive care with KC during the early hospitalization of infants with CCHD has the potential to similarly improve neurodevelopment. The purposes of the article are to describe common congenital heart defects, describe developmentally supportive care with an emphasis on KC, and to offer specific recommendations for KC and research in infants with CCHD.

Abstract
OBJECTIVES To assess health-related quality of life (HRQOL) in families of young children with complex congenital heart disease (CHD), and identify the demographic, clinical, and psychosocial factors that place these children and their mothers at greater risk of vulnerability. STUDY DESIGN This cross-sectional study took place from June 2015 to October 2016 at The Sydney Children's Hospitals Network Cardiac Service, Australia. Mothers of a child aged 1-5 years with either single ventricle CHD or CHD requiring neonatal biventricular repair were invited to participate. Eighty-seven mothers completed a suite of validated measures, including the Pediatric Quality of Life Inventory, which assessed the outcomes of child and maternal HRQOL. RESULTS Sixty percent of children with single ventricle CHD and 25% of children with biventricular repair had total Pediatric Quality of Life Inventory scores within the at-risk range. Lower child HRQOL was strongly associated with single ventricle CHD (β = -0.38; P < .001), physical comorbidity (β = -0.32; P = .001), feeding difficulties (β = -0.26; P = .008), and greater maternal psychological stress (β = -0.18; P = .045), accounting for 52% of the variance in child HRQOL. Lower maternal HRQOL was strongly associated with poorer family functioning (β = 0.61; P < .001), greater maternal psychological stress (β = -0.23; P = .004), child physical comorbidity (β = -0.17; P = .01), and a 'difficult' child temperament (β = -0.14; P = .01), accounting for 73% of the variance in maternal HRQOL. CONCLUSIONS Lower HRQOL is common in young children with complex CHD, particularly single ventricle CHD. Several predictors of HRQOL are potentially modifiable, offering possible pathways for prevention and early intervention. Routine screening is a necessary first step toward developing models of care to improve HRQOL in this population.

Abstract
BACKGROUND Children with acquired and congenital heart disease both have low mortality but an increased risk of neurologic morbidity that is multifactorial. Our hypothesis was that acute neurologic injuries contribute to mortality in such children and are an important cause of death. METHODS All admissions to the pediatric cardiac intensive care unit (CICU) from January 2011 through January 2015 were retrospectively reviewed. Patients were assessed for any acute neurologic events (ANEs) during admission, as defined by radiologic findings or seizures documented on an electroencephalogram. RESULTS Of the 1,573 children admitted to the CICU, the incidence of ANEs was 8.6%. Mortality of the ANE group was 16.3% compared with 1.5% for those who did not have an ANE. The odds ratio for death with ANEs was 8.55 (95% confidence interval, 4.56 to 16.03). Patients with ANEs had a longer hospital length of stay than those without ANEs (41.4 ± 4 vs 14.2 ± 0.6 days; p < 0.001). Need for extracorporeal membrane oxygenation, previous cardiac arrest, and prematurity were independently associated with the presence of an ANE. CONCLUSIONS Neurologic injuries are common in pediatric CICUs and are associated with an increase in mortality and hospital length of stay. Children admitted to the CICU are likely to benefit from improved surveillance and neuroprotective strategies to prevent neurologic death.

Abstract
BACKGROUND Loeys-Dietz syndrome (LDS) is a congenital multisystem disorder affecting the cardiovascular and musculoskeletal system. Limited data have reported neurodevelopmental (ND) issues in LDS. AIMS To determine the extent of ND issues in patients with LDS. METHODS A prospective study was performed of LDS patients or their caregivers. The study included data collected via an online survey of age-specific questions. Standard statistical methods were used for baseline and demographic characteristics, as well as group comparisons. OUTCOMES Data were obtained from 67 patients with LDS (54% female). Median age was 14.9 years. Gene mutations included TGFBR1 (39%), TGFBR2 (40%), SMAD3 (7%), and unknown (14%). Motor delays (30%, 18/61) and hypotonia (63%, 37/60) occurred frequently. Physical (62%, 39/62), occupational (41%, 23/56), and speech therapies (34%, 20/58) were common. Feeding issues were common (41%, 23/56). TGFBR1 mutations were more frequent among those with motor delays and feeding issues. CONCLUSIONS Patients with LDS and/or their caregivers report at least one ND problem in most cases, and many require therapies. These data suggest ND disorders should be considered to be part of the phenotype.

Abstract
Functional abilities are needed for activities of daily living. In general, these skills expand with age. We hypothesised that, in contrast to what is normally expected, children surviving the Fontan may have deterioration of functional abilities, and that peri-Fontan stroke is associated with this deterioration. All children registered in the Western Canadian Complex Pediatric Therapies Follow-up Program who survived a Fontan operation in the period 1999-2016 were eligible for inclusion. At the age of 2 years (pre-Fontan) and 4.5 years (post-Fontan), the Adaptive Behavior Assessment System-II general adaptive composite score was determined (population mean: 100, standard deviation: 15). Deterioration of functional abilities was defined as ⩾1 standard deviation decrease in pre- to post-Fontan scores. Perioperative strokes were identified through chart review. Multivariable logistic regression analysis determined predictors of deterioration of functional abilities. Of 133 children, with a mean age at Fontan of 3.3 years (standard deviation 0.8) and 65% male, the mean (standard deviation) general adaptive composite score was 90.6 (17.5) at 2 years and 88.3 (19.1) at 4.5 years. After Fontan, deterioration of functional abilities occurred in 34 (26%) children, with a mean decline of 21.8 (7.1) points. Evidence of peri-Fontan stroke was found in 10 (29%) children who had deterioration of functional abilities. Peri-Fontan stroke (odds ratio 5.00 (95% CI 1.74, 14.36)) and older age at Fontan (odds ratio 1.67 (95% CI 1.02, 2.73)) predicted functional deterioration. The trajectory of functional abilities should be assessed in this population, as more than 25% experience deterioration. Efforts to prevent peri-Fontan stroke, and to complete the Fontan operation at an earlier age, may lead to reduction of this deterioration.

Neuro-developmental outcome in single-ventricle patients: is the Norwood procedure a risk factor? Eur J Cardiothorac Surg 2018; 52:558-564. [PMID: 28472306 DOI: 10.1093/ejcts/ezx119] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2016] [Accepted: 03/19/2017] [Indexed: 11/15/2022] Open
Abstract
OBJECTIVES Complex neonatal surgery is considered a risk factor for neuro-developmental impairment in single-ventricle patients. Neuro-developmental outcome was compared between preschool-aged Fontan patients who underwent a Norwood procedure and single-ventricle patients not requiring neonatal surgery with cardiopulmonary bypass. METHODS Verbal, performance and full-scale intelligence quotient (IQ) were evaluated with the Wechsler Preschool and Primary Scale of Intelligence. Cognitive functions were assessed with the German 'Kognitiver Entwicklungstest für das Kindergartenalter' (KET-KID). Risk factors for impaired neuro-development were evaluated. RESULTS Neuro-developmental assessment was completed in 95 patients (Norwood: n = 69; non-Norwood: n = 26). Median (interquartile range) IQ and KET-KID scores were in the normal range. Except for verbal KET-KID, scores did not differ between Norwood and non-Norwood patients (verbal IQ: 98 (86-105) vs 93 (85-102), P = 0.312; performance IQ: 91 (86-100) vs 96 (86-100), P = 0.932; full-scale IQ: 93 (86-101) vs 89 (84-98), P = 0.314; KET-KID verbal: 48 (17-72) vs 25 (2-54), P = 0.020; KET-KID non-verbal: 33 (18-62) vs 45 (15-54), P = 0.771; KET-KID global: 42 (14-65) vs 28 (6-63), P = 0.208). Full-scale IQ was below average (<85 points) in 14 (20%) Norwood and 9 (35%) non-Norwood cases (P = 0.181). Global KET-KID was below average (<16th percentile) in 19 (28%) and 10 (38%) patients (P = 0.326). Smaller head circumference z-score and complications before neonatal surgery were independently associated with lower scores. CONCLUSIONS Neuro-developmental outcome of preschool-aged Fontan patients was in the normal range. The Norwood procedure was not a risk factor for neuro-developmental impairment. Preoperative condition and patient-related factors were more important determinants than variables related to surgical palliation.

Abstract
Children with congenital heart disease (CHD) have poorer neurodevelopmental and psychological outcomes. The mechanisms underlying this remain unclear. One mechanism could be that the stressful experience of cardiac surgery early in life influences long-term hypothalamic-pituitary-adrenal (HPA) axis regulation. Dysregulation of the HPA axis has been linked to poorer neurocognitive and psychological outcomes in other study populations. This case-control study aims to compare HPA-axis regulation (circadian rhythm and reactivity) using salivary cortisol in 3- to 5-year-olds with CHD who did and did not have cardiac surgery prior to 6 months of age. Saliva samples for cortisol analysis were collected from preschoolers with CHD (N = 28, Males = 18, Females = 10) over two weekend days, and before and after an echocardiogram. Caregiver education, child age, sex, and cardiac disease severity score were included as confounders. Multilevel analysis (hierarchical linear modeling) was used to analyze the data. The analysis for the cortisol circadian rhythm shows that the early surgery group has a flatter diurnal slope secondary to lower mean weekend morning waking cortisol levels than controls but similar mean bed time values. Multilevel analysis of the stress response to an echocardiogram indicates that the early surgery group has an increased response when compared to the control group. This is the first study to show that cardiac surgery prior to 6 months of age is associated with a different pattern of HPA-axis regulation at 3-5 years of age.

Abstract
Neurological and radiologic research results show an abnormal cerebral microstructure as well as abnormal neurodevelopment in patients treated for hypoplastic left heart syndrome. The aim of this study was to assess the varying cognitive performance these children have developed in dependence upon prenatal diagnosis, surgical techniques, surgical learning effects, anatomy, perfusion techniques, gender, pedagogic, and sociodemographic parameters in comparison to age-adjusted normative values. School-age children (6.3-16.9 years) with hypoplastic left heart syndrome, who were treated at the Children's heart Center Linz between 1997 and 2009, (n = 74), were surveyed in reference to cognitive achievements. 43 patients were examined prospectively by psychologists using the Wechsler intelligence scale for children IV in order to determine the respective total intelligence quotient index for each child's developmental stage. The mean index was 84.5 (percentile rank 26.4). The statistical spread and standard deviation ranged from a minimum of 40 to a maximum of 134 ± 20.8. The results for verbal comprehension, perceptual reasoning, and processing speed corresponded with total index results and were thus lower than the mean value of the normative values. The assessment of working memory showed results in the average. Prenatal diagnosis, type of lung perfusion, anatomy, and various cerebral perfusion techniques did not significantly affect the cognitive results of the patients. The results show that hypoplastic left heart syndrome patients can be successfully tutored formally as well as personally in cognitive areas, although when compared to healthy children, they showed lower results for intellectual area parameters.

Tetralogy of Fallot Surgical Repair: Shunt Configurations, Ductus Arteriosus and the Circle of Willis. Cardiovasc Eng Technol 2017; 8:107-119.

Abstract
In this study, hemodynamic performance of three novel shunt configurations that are considered for the surgical repair of tetralogy of Fallot (TOF) disease are investigated in detail. Clinical experience suggests that the shunt location, connecting angle, and its diameter can influence the post-operative physiology and the neurodevelopment of the neonatal patient. An experimentally validated second order computational fluid dynamics (CFD) solver and a parametric neonatal diseased great artery model that incorporates the ductus arteriosus (DA) and the full patient-specific circle of Willis (CoW) are employed. Standard truncated resistance CFD boundary conditions are compared with the full cerebral arterial system, which resulted 21, -13, and 37% difference in flow rate at the brachiocephalic, left carotid, and subclavian arteries, respectively. Flow splits at the aortic arch and cerebral arteries are calculated and found to change with shunt configuration significantly for TOF disease. The central direct shunt (direct shunt) has pulmonary flow 5% higher than central oblique shunt (oblique shunt) and 23% higher than modified Blalock Taussig shunt (RPA shunt) while the DA is closed. Maximum wall shear stress (WSS) in the direct shunt configuration is 9 and 60% higher than that of the oblique and RPA shunts, respectively. Patent DA, significantly eliminated the pulmonary flow control function of the shunt repair. These results suggests that, due to the higher flow rates at the pulmonary arteries, the direct shunt, rather than the central oblique, or right pulmonary artery shunts could be preferred by the surgeon. This extended model introduced new hemodynamic performance indices for the cerebral circulation that can correlate with the post-operative neurodevelopment quality of the patient.

Reduced cortical volume and thickness and their relationship to medical and operative features in post-Fontan children and adolescents. Pediatr Res 2017; 81:881-890.

Abstract
BACKGROUND We compared brain cortical and subcortical gray matter volumes and cortical thickness between post-Fontan patients and healthy controls, and examined brain anatomical associations with operative and medical history characteristics. METHODS Post-Fontan (n = 128 volumes; n = 115 thickness) and control subjects (n = 48 volumes; n = 45 thickness) underwent brain MRI at ages 10-19 y. Subcortical and cortical volumes and cortical thicknesses were measured for intergroup comparison. Associations between brain measures and clinical measures were assessed in the Fontan group. RESULTS Widespread, significant reduction in brain volumes and thicknesses existed in the Fontan group compared to controls, spanning all brain lobes and subcortical gray matter. Fontan subjects treated with vs. without the Norwood procedure had smaller volumes in several terminal clusters, but did not differ in cortical thickness. Older age at first operation and increasing numbers of cardiac catheterizations, operative complications, and catheterization complications were associated with lower regional volumes and thicknesses. Increasing numbers of operative complications and cardiac catheterizations were associated with smaller regional volumes in the Norwood group. CONCLUSION The post-Fontan adolescent brain differs from the normal control brain. Some of these differences are associated with potentially modifiable clinical variables, suggesting that interventions might improve long-term neurocognitive outcome.

Abstract
Universally fatal only 4 decades ago, the progress in the 3-stage palliation of hypoplastic left heart syndrome and related single right ventricular lesions has drastically improved the outlook for these patients. Although the stage II operation (hemi-Fontan or bidirectional Glenn) and stage III Fontan procedure have evolved into relatively low-risk operations, the stage I Norwood procedure remains one of the highest-risk and costliest common operations performed in congenital heart surgery. Yet, despite this fact, experienced centers now report hospital survivals of >90% for the Norwood procedure. This traditional 3-stage surgical palliation has seen several innovations in the past decade aimed at improving outcomes, particularly for the Norwood procedure. One significant change is a renewed interest in the right ventricle-to-pulmonary artery shunt as the source of pulmonary blood flow, rather than the modified Blalock-Taussig shunt for the Norwood. The multi-institutional Single Ventricle Reconstruction trial randomly assigned 555 patients to one or the other shunt, and these subjects continue to be followed closely as they now approach 10 years postrandomization. In addition to modifications to the Norwood procedure, the hybrid procedure, a combined catheter-based and surgical approach, avoids the Norwood procedure in the newborn period entirely. The initial hybrid procedure is then followed by a comprehensive stage II, which combines components of both the Norwood and the traditional stage II, and later completion of the Fontan. Proponents of this approach hope to improve not only short-term survival, but also potentially longer-term outcomes, such as neurodevelopment, as well. Regardless of the approach, traditional surgical staged palliation or the hybrid procedure, survivals have vastly improved, and large numbers of these patients are surviving not only through their Fontan in early childhood, but also into adolescence and young adulthood. As this population grows, it becomes increasingly important to understand the longer-term outcomes of these Fontan patients, not only in terms of survival, but also in terms of the burden of disease, neurodevelopmental outcomes, psychosocial development, and quality of life.

Abstract
OBJECTIVE To describe preschool neurodevelopmental outcomes of children with complex congenital heart disease (CHD), who were evaluated as part of a longitudinal cardiac neurodevelopmental follow-up program, as recommended by the American Heart Association and the American Academy of Pediatrics, and identify predictors of neurodevelopmental outcomes in these children. STUDY DESIGN Children with CHD meeting the American Heart Association/American Academy of Pediatrics high-risk criteria for neurodevelopmental delay were evaluated at 4-5 years of age. Testing included standardized neuropsychological measures. Parents completed measures of child functioning. Scores were compared by group (single ventricle [1V]; 2 ventricles [2V]; CHD plus known genetic condition) to test norms and classified as: normal (within 1 SD of mean); at risk (1-2 SD from mean); and impaired (>2 SD from mean). RESULTS Data on 102 patients were analyzed. Neurodevelopmental scores did not differ based on cardiac anatomy (1V vs 2V); both groups scored lower than norms on fine motor and adaptive behavior skills, but were within 1 SD of norms. Patients with genetic conditions scored significantly worse than 1V and 2V groups and test norms on most measures. CONCLUSIONS Children with CHD and genetic conditions are at greatest neurodevelopmental risk. Deficits in children with CHD without genetic conditions were mild and may not be detected without formal longitudinal testing. Parents and providers need additional education regarding the importance of developmental follow-up for children with CHD.

Abstract
BACKGROUND AND OBJECTIVES Mental health outcomes for survivors of critical congenital heart disease (CHD) remain under-investigated. We sought to examine psychiatric disorders and psychosocial functioning in adolescents with single ventricle CHD and to explore whether patient-related risk factors predict dysfunction. METHODS This cohort study recruited 156 adolescents with single ventricle CHD who underwent the Fontan procedure and 111 healthy referents. Participants underwent comprehensive psychiatric evaluation including a clinician-rated psychiatric interview and parent- and self-report ratings of anxiety, disruptive behavior, including attention-deficit/hyperactivity disorder (ADHD), and depressive symptoms. Risk factors for dysfunction included IQ, medical characteristics, and concurrent brain abnormalities. RESULTS Adolescents with single ventricle CHD had higher rates of lifetime psychiatric diagnosis compared with referents (CHD: 65%, referent: 22%; P < .001). Specifically, they had higher rates of lifetime anxiety disorder and ADHD (P < .001 each). The CHD group scored lower on the primary psychosocial functioning measure, the Children's Global Assessment Scale, than referents (CHD median [interquartile range]: 62 [54-66], referent: 85 [73-90]; P < .001). The CHD group scored worse on measures of anxiety, disruptive behavior, and depressive symptoms. Genetic comorbidity did not impact most psychiatric outcomes. Risk factors for anxiety disorder, ADHD, and lower psychosocial functioning included lower birth weight, longer duration of deep hypothermic circulatory arrest, lower intellectual functioning, and male gender. CONCLUSIONS Adolescents with single ventricle CHD display a high risk of psychiatric morbidity, particularly anxiety disorders and ADHD. Early identification of psychiatric symptoms is critical to the management of patients with CHD.

Morbidity and mortality prediction in pediatric heart surgery: Physiological profiles and surgical complexity. J Thorac Cardiovasc Surg 2017; 154:620-628.e6.

Abstract
OBJECTIVES Outcome prediction for pediatric heart surgery has focused on mortality but mortality has been significantly reduced over the past 2 decades. Clinical care practices now emphasize reducing morbidity. Physiology-based profiles assessed by the Pediatric Risk of Mortality (PRISM) score are associated with new significant functional morbidity detected at hospital discharge. Our aims were to assess the relationship between new functional morbidity and surgical risk categories (Risk Adjustment for Congenital Heart Surgery [RACHS] and Society for Thoracic Surgery Congenital Heart Surgery Database Mortality Risk [STAT]), measure the performance of 3-level (intact survival, survival with new functional morbidity, or death) and 2-level (survival or death) PRISM prediction algorithms, and assess whether including RACHS or STAT complexity categories improves the PRISM predictive performance. METHODS Patients (newborn to age 18 years) were randomly selected from 7 sites (December 2011-April 2013). Morbidity (using the Functional Status Scale) and mortality were assessed at hospital discharge. The most recently published PRISM algorithms were tested for goodness of fit, and discrimination with and without the RACHS and STAT complexity categories. RESULTS The mortality rate in the 1550 patients was 3.2%. Significant new functional morbidity rate occurred in 4.8%, increasing from 1.8% to 13.9%, 1.7%, and 12.9% from the lowest to the highest RACHS and STAT categories, respectively. The 3-level and 2-level PRISM models had satisfactory goodness of fit and substantial discriminative ability. Inclusion of RACHS and STAT complexity categories did not improve model performance. CONCLUSIONS Both mortality and new, functional morbidity are important outcomes associated with surgical complexity and can be predicted using PRISM algorithms. Adding surgical complexity to the physiologic profiles does not improve predictor performance.

Abstract
Throughout the past few decades, advances in cardiology, neonatal intensive care, and surgical techniques have resulted in a growing cohort of thriving school-aged children with previously lethal complex congenital heart diseases. While survival has increased, there remains significant morbidity following repair including neurodevelopmental sequelae. Compared to children with a structurally normal heart, these infants and children have a higher frequency of abnormalities in tone, feeding, and delayed developmental milestones, as well as challenges with speech and learning disabilities, while a higher proportion of adolescents suffer from problems with processing speed, executive function, and a unique set of medical hardships related to exercise intolerance and obesity, medication burden, and mental health comorbidities. Innovative perioperative techniques and early psychosocial intervention in these young survivors has shown that despite the obstacles, the majority of these children can grow to have fulfilling lives with intelligence and social skills in the normal range. Additionally, a comprehensive medical home aids in optimizing the quality of life for these children and their families.
