Abstract

Individuals with congenital heart disease (CHD) have an increased risk of neurodevelopmental impairments. Given the hypothesized complexity linking genomics, atypical brain structure, cardiac diagnoses and their management, and neurodevelopmental outcomes, unsupervised methods may provide unique insight into neurodevelopmental variability in CHD. Using data from the Pediatric Cardiac Genomics Consortium Brain and Genes study, we identified data-driven subgroups of individuals with CHD from measures of brain structure. Using structural magnetic resonance imaging (MRI; N = 93; cortical thickness, cortical volume, and subcortical volume), we identified subgroups that differed primarily on cardiac anatomic lesion and language ability. In contrast, using diffusion MRI (N = 88; white matter connectivity strength), we identified subgroups that were characterized by differences in associations with rare genetic variants and visual-motor function. This work provides insight into the differential impacts of cardiac lesions and genomic variation on brain growth and architecture in patients with CHD, with potentially distinct effects on neurodevelopmental outcomes.

1. Introduction

Congenital heart disease (CHD) is the most common congenital anomaly (Hoffman and Kaplan, 2002; Wu et al., 2020), accounting for approximately 3 % of infant deaths (Sadowski, 2009). Significant advances in surgical and medical treatments in the past several decades have greatly reduced mortality for individuals born with CHD (Khairy et al., 2010), making their increased likelihood for neurodevelopmental differences more apparent (Liamlahi and Latal, 2019). Approximately 10 % of children with CHD present with impairments in domains including cognition, motor, language, executive function, social interaction, attention, and impulsivity, increasing to 50 % among individuals with severe forms of CHD (Liamlahi and Latal, 2019; Marino et al., 2012). While patient-specific, postoperative, and preoperative factors have been found to be more predictive of poor neurodevelopmental outcomes in CHD than modifiable intraoperative techniques (Gaynor et al., 2007; Limperopoulos et al., 2010; Miller and McQuillen, 2007; Ortinau et al., 2018), our ability to explain much of the variance remains limited (Gaynor et al., 2007; Goldberg et al., 2019; Marino et al., 2012). Genetic and epigenetic factors have been proposed as possible contributing factors (Limperopoulos et al., 2010), with CHD and neuro-developmental differences potentially sharing genetic etiology (Homsy et al., 2015; Jin et al., 2017).

Neuroimaging is a promising approach to bridge the gap between the diverse neurodevelopmental pathways modulated by CHD-related genetic and non-genetic factors and the variability of neurodevelopmental outcomes in CHD. Magnetic resonance imaging (MRI) studies have shown altered brain maturation in utero (Limperopoulos et al., 2010; Ortinau et al., 2018; Rollins et al., 2021), thought to be caused by genetic factors and oxygen and nutrient deficiencies caused by disease-related disruptions in blood flow (Rollins et al., 2021; Sun et al., 2015). This atypical maturation has persistent effects on brain structure, such as reductions in global and regional brain volumes (Bonthrone et al., 2021), predominantly decreased cortical thickness (Verrall et al., 2021; Watson et al., 2017, 2016), reduced white matter integrity (Ehrler et al., 2021; 2020; Rollins et al., 2014; Watson et al., 2018) and altered white matter connectivity (Panigrahy et al., 2015; Schmithorst et al., 2016), which have been shown to be associated with neuro-developmental outcomes (Bonthrone et al., 2021; Ma et al., 2020; Panigrahy et al., 2015; Schmithorst et al., 2016; Verrall et al., 2021; Watson et al., 2018).

Investigations linking the atypical brain structure in CHD and the subsequent behavioral and cognitive sequelae with their genetic underpinnings are an important first step in understanding the complex relationship between genetics, brain, and behavior in CHD. Recent work from the Pediatric Cardiac Genomics Consortium’s (PCGC) Brain and Genes study (ClinicalTrials.gov #NCT01196182) was the first study to compare neurodevelopmental outcomes and brain structure in CHD individuals with (cases) and without (controls) predicted deleterious de novo variants (Morton et al., 2022). The study excluded participants with a damaging variant in a gene associated with neurodevelopmental disabilities, designed particularly to identify new genetic sources of variance in neuropsychiatric measures. Although they reported no differences in neurological outcomes between cases and controls, a small group of individuals with rare, loss-of-function (LOF) variants were found to have worse behavioral outcomes and exhibit differences in some measures of brain structure and function(Morton et al., 2022).

Studies investigating CHD have thus far employed classic case-control approaches, where differences in brain structure and/or outcome are compared between pre-specified groups. Given the hypothesized complexity of the relationships linking genomics, the various measures of brain structure, the types of cardiac lesion and their management, and subsequent neurodevelopmental outcomes, unsupervised methods with no a priori assumptions may provide unique, complementary insights into the structure of such multivariable data.

In this secondary analysis of the CHD Brain and Genes study, we used clustering techniques on measures of brain structure to identify subgroups of individuals with CHD, beyond case and control definitions. We compared the subgroups on their genetic, clinical, and behavioral characteristics to provide insights into how genomic, cardiac lesion and clinical care features may impact brain structure and ultimately neurodevelopmental outcomes. We performed clustering separately for measures derived from structural MRI (thickness and volume) and diffusion MRI (connectivity strength), allowing for different neural mechanisms and embryological origins to differentially relate to CHD pathology and neurodevelopmental outcomes.

2. Materials and methods

2.1. Participants

Participants’ data were extracted from the PCGC CHD Brain and Genes study, details of which are outlined in the primary study (Morton et al., 2022). The Pediatric Cardiac Genomics Consortium (PCGC) Brain and Genes study, a cross-sectional study performed from September 2017 to June 2020, included individuals with CHD who were at least eight years of age and who had available research-based genetic sequencing data, and excluded those who had a history of cardiac transplant, underwent a cardiac surgical procedure within six months of enrollment, had a known clinical genetic syndrome, had brain injury that a center investigator determined would overshadow the effect of a genetic variant on neurodevelopmental outcomes, lacked ability to communicate in English or Spanish, or were unable to undergo MRI scanning. Participants were also excluded if they had the presence of a clinically pathogenic copy number variant or damaging coding variant in a gene associated with neurodevelopmental delay; this criterion included both autosomal dominant genes with a single damaging variant or autosomal recessive genes where two variants were present. One hundred participants were recruited for MRI scanning at one of seven participating institutions: Boston Children’s Hospital (BCH; Boston, United States), Children’s Hospital of Philadelphia (CHOP; Philadelphia, United States), the Icahn School of Medicine at Mount Sinai (ISMMS; New York, United States), the University of California, San Francisco (UCSF; San Francisco, United States), the University of Rochester (ROC; Rochester, United States), the University of Utah (UTAH; Salt Lake City, United States), Yale University (YALE; New Haven, United States). Informed consent and assent were obtained from all participants and/or their parents or guardians. A central institutional research ethics board approved the trial’s protocol, and participating sites approved reliance agreements. This secondary analysis was also approved by the Holland Bloorview Kids Rehabilitation Hospital’s research ethics board.

2.2. Data acquisition

Information on the nature of the participant’s cardiac lesions and medical histories was obtained from chart review and participant interviews, and included the total number of cardiac surgeries, the total number of open cardiac surgeries, age at first hospital admission, and age of first open cardiac surgery. Participants were classified clinically as having either single ventricle (SV) or biventricular (BV) lesions, and the Fyler coding system was also used to categorize the lesions.

Neuroimaging data were acquired at one of seven participating institutions in the United States. Structural MRI (sMRI) data were obtained with a T1-weighted acquisition and diffusion MRI (dMRI) data were obtained with a multi-shell sequence (see the Supplemental Information and Supplemental Table 1). A neuroradiology reader assessed the structural MRIs for brain injury, providing the number of focal infarcts, the size of focal infarcts if present, and the number of foci with low and high T2 signal; a participant was determined to have MRI findings based on the presence of infarcts and/or foci. Genomic results are described in the primary study (Morton et al., 2022). Participants were classified by heterozygous status for the presence (case) or absence (control) of a damaging de novo variant in a gene that was not recognized as a definitive cause of neurodevelopmental disability (NDD; Homsy et al., 2015; Jin et al., 2017) at the time participant stratification (June 2017). Cases were further classified based on whether variants are predicted to cause loss of function (pLOF; Jin et al., 2017; Seidman et al., 2021) in a gene involved in chromatin remodelling (CHR), altered a gene that is highly expressed in the developing brain (HBE), altered a constrained gene with a high probability of intolerance to loss (H-pLI), caused a single abnormal allele in an autosomal recessive NDD gene, or occurred in a gene newly associated with NDD, after participant stratification. Note that this is distinct from the exclusion criteria at study enrollment. The NDD gene list used in this analysis phase does contain NDD genes discovered since enrollment, but most of the individuals with NDD gene variants have a single variant in a NDD gene with an autosomal recessive mechanism (while exclusion criteria required two variants). NDD gene variant status was included in our analysis to fully consider the potential impact of known NDD genes in the cohort, based on updated information at the time of analysis.

Neurocognitive testing was performed in conjunction with, or within six months of the MRI data. For the purposes of this study, we examined primary and secondary measures pre-specified in the original Brain and Genes study (Morton et al., 2022) capturing academic achievement, visual-motor integration, intelligence, memory, executive function and added the Vineland Adaptive Behavior Scales, Third Edition (Vineland-3; Sparrow et al., 2016) from exploratory measures to capture overall adaptive function.

2.3. Preprocessing

For the sMRI preprocessing, the Adolescent Brain Cognitive Development (ABCD) Study pipeline was performed (Hagler et al., 2019). The dMRI data were preprocessed and reconstructed using QSIPrep (version 0.14.3; Cieslak et al., 2021), followed by tractography to generate structural connectivity networks of streamline count between pairs of regions in the FreeSurfer cortical and subcortical parcellation. Further details are provided in the Supplemental Information. ComBat harmonization (Fortin et al., 2018) was used to correct for site effects, and the effects of age at imaging (linear and quadratic), sex, and intracranial volume were regressed from each measure. For both steps, bootstrapping (63.2 % of the sample (Efron, 1979), 100,000 iterations) was used to increase robustness (Da-ano et al., 2020). The residual data were z-scored for the clustering analysis.

2.4. Clustering

The clustering pipeline was run separately for the sMRI and dMRI data. The pipeline consisted of 100,000 bootstrap iterations, each with 63.2 % of the sample, the square root of the number of features (Efron, 1979), and the number of clusters pre-selected as a value between two and five. The difference between pairs of participants was computed for each selected feature, converted to a similarity matrix (Ontanon, 2020), and averaged across all features; spectral clustering (Ng et al., 2001) was then performed using the pre-selected number of clusters. These 100,000 clustering solutions were collected and used to generate a participant co-assignment matrix containing the probability pairs of participants were clustered together across the bootstrap iterations. Finally, hierarchical clustering was performed on the co-assignment matrix. Hierarchical clustering produces a dendrogram, or clustering decision tree, where for each layer (two to five considered in this study) a root node is split into two leaves. Further details on the clustering pipeline are provided in the Supplemental Information.

2.5. Statistics

Differences in participant demographics, CHD lesion categories, genetic categories, MRI findings, and behavioural measures between pairs of leaves in each layer of the dendrograms were evaluated using chi-squared tests for categorical variables, ordinal logistic regression for ordinal variables, and either one-way analysis of variances (ANOVAs) or Kruskal-Wallis tests for continuous variables depending on normality; participants with missing data were excluded on a case-by-case basis, and significance was held at p < 0.05, uncorrected. Differences in the brain measures between the leaf clusters were also tested and resulting p-values were corrected across the brain regions (Benjamini and Hochberg, 1995), holding significance at pcorr<0.05.

In the first layer of the dendrogram, the sample is split into Subgroup-A1 and Subgroup-B1, which show differences in CHD category and language abilities. Specifically, a higher proportion of the individuals with SV lesions were classified into Subgroup-A1 compared to Subgroup-B1, and the SV-enriched subgroup performed worse on all three language measures compared to the BV-dominant subgroup. The SV-enriched subgroup was characterized by widespread decreases in cortical thickness, cortical volume, and subcortical volume, with nearly all regions showing significant differences. As an exploratory analysis, we also performed within-lesion comparisons between the leaf clusters; results are presented in the Supplemental Information.

In the second layer of the dendrogram, the SV-enriched Subgroup-A1 was split into Subgroup-D1 and Subgroup-C1, who differed in the proportion of individuals with a d-transposition of the great arteries: all eight of the participants with this lesion belonged to Subgroup-D1. Localized increases in cortical thickness and cortical volume were observed in Subgroup-D1.

In the next layer, the BV-dominant Subgroup-B1 was split into Subgroup-E1 and Subgroup-F1, which differed in CHD diagnosis, the presence of a pLOF variant in a HBE gene, the presence of a pLOF variant in a H-pLI gene, and the socialization domain of adaptive functioning. Subgroup-F1 contained over half the SV individuals, and Subgroup-E1 contained over 80 % of the BV individuals as well as most of the individuals with a pLOF variant in HBE and H-pLI genes (14 of these individuals had co-occurring variants, eight of whom had a single variant that met criteria for both). However, despite having a decreased genetic impact, the subgroup with most SV individuals had a 14-point reduction in the socialization domain of adaptive functioning compared to Subgroup-E1. Subgroup-F1 had widespread decreased cortical thickness in all lobes, and localized increased volume compared to Subgroup-E1.

Finally, in the last layer of the dendrogram presented, the BV-dominant subgroup with more individuals with pLOF variants (Subgroup-E1) was split into Subgroup-G1 and Subgroup-H1, which differed in the presence of a pLOF variant in an gene newly identified as a dominant neurodevelopmental disability gene or a single variant in a recessive NDD gene (detailed in Data acquisitions), in executive functioning and in the communication domain of adaptive functioning. However, the sample size at this layer is small, and no differences in thickness and volume survived multiple comparisons.

In the first layer of the dendrogram, the sample is split into Subgroup-A2 and Subgroup-B2, which differ in the presence of a rare pLOF variant in an HBE gene and visual motor integration. Subgroup-B2 contained a higher proportion of those with an HBE gene and had better visual motor integration compared to Subgroup-A2. Subgroup-B2 had decreased structural connectivity strength in regions throughout the brain, spanning all lobes and subcortical structures.

In the next layer of the dendrogram, the HBE-dominant Subgroup-B2 was split into Subgroup-C2 and -D2 who differed in household income level. Given the trend (p < 0.07) for the proportion of individuals with a rare pLOF variant in HBE and H-pLI genes, we examined individuals with rare variants in both types of genes (a “combined hit”; 22 individuals, 12 of whom had a single variant that met criteria for both). A significant difference was observed (X2(54) = 4.13, p = 0.04), with Subgroup-D2 having a higher proportion of individuals with a rare HBE and H-pLI variant compared to Subgroup-C2. Subgroup-C2 had decreased structural connectivity strength in cortical regions (primarily in the bilateral parietal and frontal lobes) and increased strength in subcortical regions compared to Subgroup-D2.

In the fourth layer of the dendrogram, Subgroup-C2, the group with fewer individuals with combined HBE and H-pLI genetic hits, was split into Subgroup-E2 and -F2, which differed in processing speed index and executive functioning. Subgroup-F2 performed better on these measures compared to Subgroup-E2 and had localized increases in connectivity strength compared to Subgroup-E2.

In the final layer of the dendrogram, the HBE and H-pLI-dominant subgroup (Subgroup-D2) was split into Subgroup-G2 and -H2, which differed in several clinical and behavioural variables. However, results should be interpreted with the small sample size at this stage of the dendrogram in mind.

4. Discussion

Here, we undertook an unsupervised data-driven approach to show that in patients with CHD, specific measures of brain structure can delineate subgroups that have differential associations with cardiac diagnosis and related clinical characteristics, genetics, and ultimately neurodevelopmental outcomes. In general, groups based on cortical thickness and volume are more likely to reflect differences in basic cardiac anatomy and are associated with differences in language performance, whereas groups based on brain structural connectivity are more likely to reflect genomic variation and are mostly associated with differences in visual-motor integration.

Our study uses the first cohort of individuals with CHD for whom extensive genetic and neuroimaging measures had been obtained. While cortical and subcortical morphology and white matter connectivity are known to be influenced by both genetic, environmental, and CHD-specific factors (Bonthrone et al., 2021; Panigrahy et al., 2015; Verrall et al., 2021; Winkler et al., 2010; Yeh et al., 2016), we demonstrate that unsupervised data-driven approaches can identify associations between distinct brain measures and lesion- and genetic-specific influences of CHD on neurodevelopmental outcomes. These observations improve our understanding of the complex and heterogeneous relations between genetics, brain, and behavior in CHD which have not yet been apparent using classic case-control approaches. Our data contributes to the growing body of literature advocating for data-driven approaches to enhance our understanding of differences in brain development and the associated heterogeneity in both the factors contributing to its origins and downstream developmental trajectories of behavior and cognition (Zhang et al., 2020).

When using sMRI measures (thickness and volume), the primary division revealed two subgroups characterized by significantly different proportions of the single-ventricle and biventricular participants, with the subgroup with more single-ventricle individuals being associated with decreased thicknesses and volumes and decreased performance on language measures. The observation confirms the idea that the presence of a single ventricle has profound effect on brain structure which may be independent of a genetic effect and aligns with previous literature reporting widespread decreases in volumes and thickness across the lifespan as well as decreased language abilities in single ventricle cohorts (Brosig et al., 2013; Burns et al., 2021; Claessens et al., 2016; Clouchoux et al., 2013; Hiraiwa et al., 2020; Hövels-Gürich et al., 2008; Mahle et al., 2000; Rajagopalan et al., 2018; Singh et al., 2018; Verrall et al., 2021; Watson et al., 2017). Lower in utero substrate delivery to the brain may contribute, in part, to diminished brain volume and cortical thickness, which can increase the likelihood of neurodevelopmental differences. This is supported by the observation that most of the individuals with d-TGA, who are expected to also have poor substrate and oxygen delivery, were clustered into the subgroup that was single-ventricle enriched.

Decreased cortical thickness and cortical volume were observed in the single-compared to bi-ventricular subgroup throughout the brain. Decreased cerebral volume in individuals with CHD compared to typical development has been reported throughout the lifespan, with some evidence of larger reductions in individuals with single-ventricular and cyanotic CHD (see (Bonthrone et al., 2021) for a review), aligning with our findings. For cortical thickness, the largest effects were observed in bilateral entorhinal cortices (part of the medial temporal lobe), pars orbitales (part of the inferior frontal gyrus), and isthmus of the cingulate gyri, and for cortical volume, some of the largest effects were also observed in similar regions (specifically, the right caudal anterior cingulate gyri and the right entorhinal cortex). Decreases in the volumes and thicknesses of frontal, temporal, and cingulate regions have been reported in severe CHD compared to controls throughout development (Cordina et al., 2014; Ortinau et al., 2012; Singh et al., 2018). The pars orbitalis is a well-established region in the language processing network (Price, 2010). Furthermore, the entorhinal cortices and cingulate gyri are part of the limbic system, which is frequently implicated memory (Rolls, 2015), a function that has classically been viewed as distinct from language. However, recent advances in our understanding of cross-function relationships have proposed a language-and-memory network (Banjac et al., 2021b, 2021a; Roger et al., 2022; 2020). This network is thought to be responsible for the intersection of language and declarative memory and includes the entorhinal cortex and isthmus of the cingulate gyri (Roger et al., 2022). Together, this suggests that alterations in the cortical thickness and volume of these brain regions may be the underlying mechanism accompanying differences in language ability. This is supported by evidence in the existing literature, which has shown associations between whole brain and temporal lobe volumes and language ability in CHD (Jakab et al., 2019; Meuwly et al., 2019).

Further division of the biventricular-dominant group revealed two subgroups that contained statistically different proportions of individuals with rare pLOF variants in addition to lesion type. In this higher performing group with predominantly more benign cardiac lesions, the influence of genomic variation starts to become apparent. However, even within this group, those with single ventricles had fewer rare genetic variants and decreased performance, highlighting, again, the impact of single ventricle physiology in the fetal, perinatal, and peri- and postoperative periods on brain development (Clouchoux et al., 2013; Kelly et al., 2017; Newburger et al., 2012; Sun et al., 2015; Zeng et al., 2015).

We chose to investigate structural connectivity separately from brain volume and cortical thickness given their distinct embryological origin, developmental timing, and effects on development. In the first division of the structural connectivity analysis, we identified two subgroups that differed in the proportion of those with rare pLOF variants in HBE genes. The subgroup with more genetic variants was associated with decreased white matter connectivity strength compared to the group with fewer such variants. Despite both groups scoring below average in visual-motor integration, as expected from previous studies (Bellinger and Newburger, 2016; Schaefer et al., 2013; Teixeira et al., 2021), the subgroup with more genetic variants performed better on visuomotor integration. This is the first report of structural connectivity differences between subgroups with differing proportions of pLOF variants. While the primary study examined measures of white matter integrity, finding differences between those with and without a variants in an NDD risk gene, white matter connectivity was not examined (Morton et al., 2022). Some of the largest effect sizes of connectivity strength differences between these two subgroups were observed in the bilateral precentral gyri, right inferior parietal lobule, left lateral occipital cortex and bilateral insulae, amongst others. The primary motor cortex is located within the precentral gyrus (Banker and Tadi, 2021), while the lateral occipital cortex is associated with both the dorsal and ventral visual streams (Goodale and Milner, 2018, 1992), and the parietal lobules and insulae have been shown to be important visuomotor integration (Andersen, 1987; Cauda et al., 2011; Sepulcre, 2014). Together, our results suggest a link between pLOF variants in HBE genes in individuals with CHD with white matter connectivity strength in visuomotor-related regions, which has functional implications. In the subsequent division, the subgroups again separate based on proportion of individuals with pLOF variants, further underscoring that white matter connectivity measures track with genetic influences in CHD.

This study takes a step towards personalized approaches to the care of children with CHD and potential neurodevelopmental concerns. Our current ability to explain the variability of neurodevelopmental conditions in CHD is limited (Gaynor et al., 2007; Goldberg et al., 2019; Marino et al., 2012). This has meant that we are currently unable to confidently determine who is at risk of developing poor outcomes, challenging our ability to deliver anticipatory guidance and secondary prevention interventions before challenges emerge. This calls for a precision medicine approach that takes into consideration each patient’s neurobiology alongside their clinical and genetic factors. As a first step, we identified subgroups of individuals with CHD with specific patterns of brain structure that are associated with less optimal neurodevelopmental outcomes. Although this is not ready for clinical use at this point, as precision medicine advances, subgroups based on brain and other biological markers which predict specific developmental trajectories, will be identified to facilitate the early detection of patients with a high risk of poor neurodevelopmental outcomes. Clinicians then will develop anticipatory guidelines and proactively intervene to optimize outcomes, ultimately improving the quality of life of those affected.

We acknowledge the sample sizes required for reproducible results in neuroimaging studies and the necessity to replicate data-driven approaches in independent samples to enable the clinical translation of findings (Fröhlich et al., 2018; Klapwijk et al., 2021; Marek et al., 2022), and thus the sample size and lack of a replication cohort is a limitation to our study. The sample size increases the risk of type II errors and has also restricted our diffusion features to connectivity strength rather than the raw connectivity values, as otherwise, the number of features would exceed the number of samples, which can lead to less meaningful and interpretable subgroups (Assent, 2012). We also took an exploratory approach to this study given its novelty and our limited sample size, and thus did not correct for multiple comparisons across the behavioural measures, to avoid missing important signal to be explored in future studies. However, we are the first to use such approaches with extensive neuroimaging and genetic measures collected on a cohort of individuals with congenital heart disease and as such no replication cohort is available yet. Our work highlights the importance of understanding both genomic influences and heart anatomy and related factors to influence neurodevelopmental outcomes in individuals with CHD, and advocates for future studies to collect neuroimaging, genetic, clinical, and behavioural measures to allow for further delineation of such influences in large samples and the ability to independently replicate.

This study had several other limitations. We have used cross-sectional data, which only captures neurobiology and cognition at a specific point in time. Future studies should take a longitudinal approach, tracking developmental trajectories of brain structure and connectivity to better understand their impact on neurodevelopmental outcomes in CHD; in particular, the stability of data-driven subgroups across development should be investigated. Other limitations include only studying rare pLOF variants in four gene categories and the exclusion of participants with genetic variants known to be associated with neurodevelopmental delay or impairment. We also did not evaluate for subdural hemorrhage and other known confounding morbidities that affect neurodevelopmental outcomes such as history of prematurity, access to care, race, ethnicity, and the cumulative burden of ionizing radiation from medical imaging procedures (Pasqual et al., 2021). We did consider whether household income and maternal education level as a proxy for social determinants of health contributes to the subgroupings; however, in our dataset we see its contributions further in the dendrogram suggesting that much larger sample sizes may be required to understand the impact of social determinants of health. We also used the FreeSurfer gray matter cortical and subcortical parcellation for diffusion tractography, which may not be the most suitable due to the unreliability of tensor fitting near gray matter regions; however, using the same parcellation for the sMRI and dMRI clustering procedure ensured we were able to make cross-modality comparisons. Of note, we have only used measures of neurobiology to derive the subgroups; while neurobiology acts as an intermediary between the diverse neurodevelopmental pathways modulated by clinical, genetic, and environmental factors and the variability of outcomes in CHD, future work could also use these factors to inform the subgroups.

In conclusion, we used a data-driven approach to investigate the relation between patterns of brain structure/connectivity, rare genomic variation and types of cardiac lesions and behaviour and cognition in individuals with CHD. We identified that whereas measures of cortical thickness and cortical and subcortical volumes mostly relate to cardiac lesion anatomical type and subsequent language outcomes, white matter connectivity strength was more associated with the presence or absence of rare loss-of-function genetic variants and subsequent visuo-motor integration differences. Such insights are foundational to our understanding of distinct impacts of cardiac anatomy versus genomic variation on brain structure and associated neurodevelopmental effects.
