Maternal occupational exposure to polycyclic aromatic hydrocarbons and the risk of isolated congenital heart defects among offspring. ENVIRONMENTAL RESEARCH 2020; 186:109550. [PMID: 32335433 PMCID: PMC8756335 DOI: 10.1016/j.envres.2020.109550] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/29/2020] [Revised: 04/07/2020] [Accepted: 04/15/2020] [Indexed: 05/19/2023]
Abstract
BACKGROUND Although there is evidence in experimental model systems that exposure to polycyclic aromatic hydrocarbons (PAHs) is linked with congenital heart defects (CHDs), few studies have examined the association in humans. We conducted a case-control study to examine the association between maternal exposure to PAHs and CHDs in offspring using data from the National Birth Defects Prevention Study (NBDPS) (1997-2011). METHODS We obtained detailed information on maternal occupation during the month before to three months after conception. Expert raters, masked to case-control status, assessed job descriptions to assign categorical levels of exposure. Categories were quantitatively mapped to estimate cumulative exposure to PAHs, incorporating exposure intensity, frequency, work duration, and work hours. Quartiles were generated for cumulative maternal exposure to PAHs. Crude and adjusted odds ratios (ORs) with 95% confidence intervals (CIs) were estimated using unconditional logistic regression for quartiles of PAH exposure and six CHD groupings (e.g. conotruncal) and specific subtypes (e.g. tetralogy of Fallot [ToF]). Final models were adjusted for maternal age, race/ethnicity, education, smoking, anticonvulsant use, folic acid supplementation, and study center. RESULTS There were 4,775 case and 7,734 control infants eligible for the study. The prevalence of occupational exposure to PAHs was 10.2% among both case and control mothers. In adjusted analysis, compared to mothers with no occupational PAH exposure, those in the highest quartile of exposure were more likely to have offspring in the conotruncal heart defects group (OR 1.41; 95% CI 1.00-2.00), and with ToF (OR 1.83; 95% CI 1.21-2.78). CONCLUSIONS Women in the highest quartile of estimated cumulative occupational PAH exposure during early pregnancy were more likely to have offspring with conotruncal heart defects, specifically ToF, compared to women with no occupational PAH exposure. Other comparisons between PAHs and other CHDs subgroups did not show any statistically precise associations.

Hwang JH, Chae SM. Experiences of Fathers of Young Children With Severe Congenital Heart Defects in Korea: A Qualitative Descriptive Study. J Pediatr Nurs 2020; 53:e108-e113. [PMID: 32178884 DOI: 10.1016/j.pedn.2020.02.040] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Revised: 02/23/2020] [Accepted: 02/24/2020] [Indexed: 01/09/2023]
Abstract
PURPOSE This qualitative descriptive study sought to explore the experiences of fathers of children with severe congenital heart defects (CHDs) in Korea. METHODS The participants were nine fathers of children under 5 years of age who had undergone open heart surgery within the last 5 years. Data were collected using in-depth individual interviews from February to March 2015. Qualitative data were analyzed using the thematic analysis method. RESULTS Three themes and nine sub-themes emerged from the data. The three themes were "heartbreaking suffering," "self-control during a great struggle," and "being a father of a child with CHD." This study described coping strategies that fathers used to balance their life, including self-control, redefinition of the situation, and seeking family support resources, which enabled them to practice normalization and live an ordinary life despite limitations. CONCLUSION The findings of this study indicate that considerable psychological distress of fathers was similar to that of mothers for weeks to months after the sudden diagnosis of CHD and heart operations. The results also depict the coping strategies, contemporary fathering experience and the parenting role of fathers in raising children with severe CHDs. PRACTICE IMPLICATIONS Healthcare professionals should understand the experience of fathers of children with severe CHDs and their needs for social support. It is also necessary to develop nursing interventions that focus on fathers' needs.

Gene-environment regulation of chamber-specific maturation during hypoxemic perinatal circulatory transition. J Mol Med (Berl) 2020; 98:1009-1020. [PMID: 32533200 DOI: 10.1007/s00109-020-01933-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/17/2020] [Revised: 05/12/2020] [Accepted: 05/28/2020] [Indexed: 10/24/2022]
Abstract
Chamber-specific and temporally regulated perinatal cardiac growth and maturation is critical for functional adaptation of the heart and may be altered significantly in response to perinatal stress, such as systemic hypoxia (hypoxemia), leading to significant pathology, even mortality. Understanding transcriptome regulation of neonatal heart chambers in response to hypoxemia is necessary to develop chamber-specific therapies for infants with cyanotic congenital heart defects (CHDs). We sought to determine chamber-specific transcriptome programming during hypoxemic perinatal circulatory transition. We performed transcriptome-wide analysis on right ventricle (RV) and left ventricle (LV) of postnatal day 3 (P3) mouse hearts exposed to perinatal hypoxemia. Hypoxemia decreased baseline differences between RV and LV leading to significant attenuation of ventricular patterning (AVP), which involved several molecular pathways, including Wnt signaling suppression and cell cycle induction. Notably, robust changes in RV transcriptome in hypoxemic condition contributed significantly to the AVP. Remarkably, suppression of epithelial mesenchymal transition (EMT) and dysregulation of the TP53 signaling were prominent hallmarks of the AVP genes in neonatal mouse heart. Furthermore, members of the TP53-related gene family were dysregulated in the hypoxemic RVs of neonatal mouse and cyanotic Tetralogy of Fallot hearts. Integrated analysis of chamber-specific transcriptome revealed hypoxemia-specific changes that were more robust in RVs compared with LVs, leading to previously uncharacterized AVP induced by perinatal hypoxemia. Remarkably, reprogramming of EMT process and dysregulation of the TP53 network contributed to transcriptome remodeling of neonatal heart during hypoxemic circulatory transition. These insights may enhance our understanding of hypoxemia-induced pathogenesis in newborn infants with cyanotic CHD phenotypes. KEY MESSAGES: During perinatal circulatory transition, transcriptome programming is a major driving force of cardiac chamber-specific maturation and adaptation to hemodynamic load and external environment. During hypoxemic perinatal transition, transcriptome reprogramming may affect chamber-specific growth and development, particularly in newborns with congenital heart defects (CHDs). Chamber-specific transcriptome changes during hypoxemic perinatal transition are yet to be fully elucidated. Systems-based analysis of hypoxemic neonatal hearts at postnatal day 3 reveals chamber-specific transcriptome signatures during hypoxemic perinatal transition, which involve attenuation of ventricular patterning (AVP) and repression of epithelial mesenchymal transition (EMT). Key regulatory circuits involved in hypoxemia response were identified including suppression of Wnt signaling, induction of cellular proliferation and dysregulation of TP53 network.

Non-Newtonian Effects on Patient-Specific Modeling of Fontan Hemodynamics. Ann Biomed Eng 2020; 48:2204-2217. [PMID: 32372365 DOI: 10.1007/s10439-020-02527-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/11/2019] [Accepted: 04/29/2020] [Indexed: 12/15/2022]
Abstract
The Fontan procedure is a common palliative surgery for congenital single ventricle patients. In silico and in vitro patient-specific modeling approaches are widely utilized to investigate potential improvements of Fontan hemodynamics that are related to long-term complications. However, there is a lack of consensus regarding the use of non-Newtonian rheology, warranting a systematic investigation. This study conducted in silico patient-specific modeling for twelve Fontan patients, using a Newtonian and a non-Newtonian model for each patient. Differences were quantified by examining clinically relevant metrics: indexed power loss (iPL), indexed viscous dissipation rate (iVDR), hepatic flow distribution (HFD), and regions of low wall shear stress (AWSS). Four sets of "non-Newtonian importance factors" were calculated to explore their effectiveness in identifying the non-Newtonian effect. No statistical differences were observed in iPL, iVDR, and HFD between the two models at the population-level, but large inter-patient variations exist. Significant differences were detected regarding AWSS, and its correlations with non-Newtonian importance factors were discussed. Additionally, simulations using the non-Newtonian model were computationally faster than those using the Newtonian model. These findings distinguish good importance factors for identifying non-Newtonian rheology and encourage the use of a non-Newtonian model to assess Fontan hemodynamics.

Abstract
OBJECTIVE We present a familial 21q22.3 microduplication in a fetus associated with prenatally detected congenital heart defects (CHD). CASE REPORT A 38-year-old woman underwent amniocentesis at 22 weeks of gestation because of sonographic findings of double outlet of right ventricle, ventricular septal defect and transposition of great artery in the fetus. Her husband was 42 years old, and there was no CHD and congenital malformation in the family. Cytogenetic analysis revealed a karyotype of 46,XY in the fetus. Simultaneous array comparative genomic hybridization (aCGH) analysis using uncultured amniocytes revealed a 0.56-Mb microduplication of 21q22.3 or arr 21q22.3 (47,482,210-48,043,704)×3.0 [GRCh37 (hg19)] encompassing nine Online Mendelian Inheritance in Man (OMIM) genes of FTCD, SPATC1L, LSS, MCM3AP, YBEY, PCNT, DIP2A, S100B and PRMT2. aCGH analysis of the parental bloods revealed that the phenotypically normal father carried the same microduplication. The parents decided to continue the pregnancy, and a 3168-g male baby was delivered at term without Down syndrome phenotype except CHD. Mutational analysis of the CRELD1 gene on the DNA extracted from the cord blood showed no mutation in CRELD1. Postnatal molecular cytogenetic analysis of the cord blood confirmed the prenatal diagnosis. The infant underwent a successful heart surgery to correct the CHD and was doing well without psychomotor or developmental delay at six months of age. CONCLUSION Prenatal diagnosis of 21q22.3 microduplication associated with CHD should include a differential diagnosis of Down syndrome.

Abstract
BACKGROUND Rubinstein-Taybi syndrome (RTS) is a rare, congenital, plurimalformative, and neurodevelopmental disorder. Previous studies have reported that large deletions contribute to more severe RTS phenotypes than those caused by CREBBP point mutations, suggesting a concurrent pathogenetic role of flanking genes, typical of contiguous gene syndromes, but the detailed genetics are unclear. RESULTS This study presented a rare case of Rubinstein-Taybi (RT) syndrome with serious cardiac abnormalities. Based on the clinical and genetic analysis of the patient, the ADCY9 gene deletion was highlighted as a plausible explanation of cardiac abnormalities. In adcy9 morphant zebrafish, cardiac malformation was observed. Immunofluorescence study disclosed increased macrophage migration and cardiac apoptosis. RNA sequencing in zebrafish model highlighted the changes of a number of genes, including increased expression of the mmp9 gene which encodes a matrix metalloproteinase with the main function to degrade and remodel extracellular matrix. CONCLUSIONS In this study, we identified a plausible new candidate gene ADCY9 of CHD through the clinical and genetic analysis of a rare case of Rubinstein-Taybi (RT) syndrome with serious cardiac abnormalities. By functional study of zebrafish, we demonstrated that deletion of adcy9 is the causation for the cardiac abnormalities. Cardiac apoptosis and increased expression of the MMP9 gene are involved in the pathogenesis.

Abstract
Background: The families of children with congenital heart disease experience significant stress as to the care of the child and need
to cope with stress. Accordingly, understanding of how families cope and use coping strategies is more important to help
them better cope with stressful situations caused by caregiving. This study aimed to explore coping strategies used by families in the face of caregiving stress. Methods: This qualitative study was conducted on 40 eligible participants from the families of children with congenital heart disease. They were
recruited through a purposive sampling method from those referred to hospitals in Mashhad, Iran. In-depth and semi-structured interviews
were used for data collection from November 2017 to December 2018. The data were analyzed using conventional content analysis,
and MAXQDA software (Ver.2010) was used to manage the data encoding process. Results: According to the results, effort to maintain well-being emerged as the main theme which included five categories:
“spirituality in caregiving”, “acceptance and adjustment”, “optimism and hopefulness”, “self-control and patience”, and “ management of psychological needs”. Conclusion: Families used various coping strategies including spirituality, acceptance, optimism, patience, and management of psychological
needs based on their beliefs, attitudes, abilities, and available resources for coping with caregiving stress. The results can help
the nurses and health care professionals to develop appropriate educational, supportive, and psychological interventions based
on the family’s needs to cope effectively with caregiving stress.

Abstract
Background Chylothorax after congenital heart surgery is not an uncommon complication, and it is associated with significant morbidity. However, consensus treatment guidelines are lacking. To improve the treatment outcomes of patients with postoperative chylothorax, we implemented a standardized management protocol at Severance Hospital in September 2014. Methods A retrospective review of patients treated at a single center was done. All corrective and palliative operations for congenital heart disease performed at our institution between January 2008 and April 2018 were reviewed. The incidence and treatment outcomes of postoperative chylothorax were analyzed. Results The incidence of chylothorax was 1.9%. Sixty-one percent of the patients could be managed with a low-fat diet, while 28% of the patients required complete restriction of enteral feeding. Thoracic duct embolization was performed in 2 patients and chest tube drainage decreased immediately after the procedure. No patient required thoracic duct ligation or pleurodesis. After implementation of the institutional management protocol, the number of chest tube drainage days decreased (median, 24 vs. 14 days; p=0.45). Conclusion Implementing a strategy to reduce postoperative chylothorax resulted in an acceptable incidence of postoperative chylothorax. Instituting a clinical practice protocol helped to curtail the treatment duration and to decrease the requirement for surgical treatment. Image-guided embolization of the thoracic duct is an effective treatment for postoperative chylothorax.

Abstract
Single ventricle congenital heart defect patients have improved survival with Fontan palliation. However, they remain at risk for nephropathy, as indicated by pathologic microalbuminuria. We sought to investigate whether echocardiographic measures of the inferior vena cava diameter (a surrogate for elevated CVP) indexed to the body surface area (iIVC) or cardiac index (CI) can predict the presence of nephropathy in Fontan patients. We performed a single-center case-control study, including 39 asymptomatic Fontan (age 14.8 ± 7.9 years) and 29 healthy controls (age 12.7 ± 2.7 years). The primary outcome was abnormal microalbumin-creatinine ratio (MCR) from the first-morning void urine in Fontan patients. Measurements of iIVC and CI were derived using transthoracic echocardiography by two investigators with a high intra-class correlation coefficient (ICC = 0.97). Group comparison between Fontan and controls as well as between Fontan with normal and abnormal MCR was performed using Fisher's exact and t tests. Pearson and Spearman's correlations and multivariate regressions were performed to analyze the relations between the MCR, iIVC, and CI. Abnormal MCR was noted in 13/39(33%) of Fontan patients. The mean iIVC was larger in the Fontan compared to controls (p < 0.0001) and in Fontan with abnormal MCR compared to those with normal MCR (p = 0.0006). A positive correlation (r = 0.62; p < 0.001) was noted between MCR and iIVC. All patients with abnormal MCR had the iIVC > 1 cm/m2. There were no significant relations between the CI and MCR. Significant prevalence of nephropathy late after Fontan palliation warrents screening. Echocardiographic measurement of iIVC could serve as one of the screening measures. The finding of the iIVC diameter > 1 cm/m2 should prompt further renal evaluation.

Abstract
BACKGROUND Pre-pregnancy diabetes is a strong risk factor for congenital heart defects (CHDs), suggesting a role for glucose in the causal pathway. Oral corticosteroids may cause hyperglycemia and maternal use could affect embryonic heart development. The objective of this study was to determine the association between maternal intake of oral corticosteroids 0-8 weeks after conception and CHDs in offspring. METHODS A register-based nationwide prevalence study including all live singleton births in Denmark, 1996-2016, was conducted. In total, 1 194 687 individuals and their mothers were identified and linked with information on offspring CHDs and the mothers' use of oral corticosteroids in early pregnancy. Corticosteroid use was defined as a filled prescription for maternal use of oral corticosteroid 0-8 weeks after conception. CHDs were identified through International Classification of Diseases codes. The association was estimated by prevalence (odds) ratios using logistic regression and propensity score-matched analyses. RESULTS Among 1 194 687 live births, 2032 had a mother who had used oral corticosteroids 0-8 weeks from conception. Of these offspring, 32 had a heart defect. Among the offspring of never-users of oral corticosteroids, 10 534 had a heart defect. The adjusted prevalence ratio was 1.29 (95% confidence interval, 0.90-1.84) comparing offspring prevalence of heart defects in oral corticosteroid users with that in oral corticosteroid never-users. Propensity score-matched analysis yielded similar results (prevalence ratio 1.38; 95% confidence interval, 0.95-2.02). CONCLUSIONS This study supports that there is no association between maternal use of oral corticosteroids in the first 8 weeks after conception and CHDs.

Abstract
OBJECTIVES The modified extracardiac Fontan of direct total cavopulmonary connection (dTCPC) with entirely autologous vessels is a better solution in selected patients with functionally univentricular hearts because it combines the advantages of a tubular connection and of full growth potential. We investigated the mid-term to long-term outcomes of the physical condition of patients who had the dTCPC and assessed the growth potential of the autologous dTCPC pathway. METHODS From July 2005 to June 2014, 31 patients, aged 1.8-14.0 years, underwent a modified extracardiac Fontan with dTCPC at our institution. Twenty-two patients underwent a 1-stage dTCPC and 9 patients underwent a 2-stage dTCPC. The preoperative and postoperative data were reviewed retrospectively. RESULTS There were 17 (54.8%) boys and 14 (45.2%) girls, with a median age of 6.4 years (range 1.8-14.0 years) and a mean weight of 17.8 kg (range 9-41 kg). The mean follow-up period was 6.0 years (range 2.1-10.2 years). There was 1 early death and 2 late deaths. The event-free survival rate for the 31 patients was 88.9% at 10 years during the follow-up period. Late protein-losing enteropathy, thromboembolism, arrhythmia or heart failure were not observed. There was a significant difference between the preoperative and postoperative data for body mass index and the diameters of the autologous dTCPC pathway and pulmonary artery branches, confirming that the growth potential of the autologous dTCPC pathway was realized. CONCLUSIONS The dTCPC procedure could be performed with satisfactory midterm to long-term outcomes in selected patients. It has the potential of retaining the advantage of the extracardiac Fontan operation together with the potential for growth and the avoidance of prosthetic materials.

Abstract
Congenital heart defects (CHD) are the most common form of birth anomalies. About one-fifth of these are critical requiring very early intervention, the classical examples being transposition of great arteries or obstructive total anomalous pulmonary venous connection. On the other hand, relatively milder and simpler lesions, such as small ventricular septal defects or mild pulmonary stenosis, may either not need intervention at all or intervened as and when deemed necessary. Apart from the cardiovascular effects, some CHDs can significantly affect the physical growth and neurodevelopment of the child. Each type of CHD has unique hemodynamic effects and the intervention is, by and large, timed based on the severity and natural history of each cardiac lesion. Some lesions have a "limited" time window beyond which they may become unsuitable for any intervention. Hence it is critical to intervene at the appropriate time so as to prevent the untoward effects of CHDs and at the same time to avoid unnecessary interventions.

Abstract
BACKGROUND An increasing number of research projects are now collaborating with persons who have lived experience of a specific health-related situation, such as a prenatal diagnosis of congenital heart defect. Such collaboration has the potential to provide valuable insights how to plan future studies, but little is known how these persons experience such involvement. The aim was to explore how persons with lived experience of a prenatal diagnosis perceived collaborating in a research project utilizing patient and public involvement to identify relevant research questions and develop suitable interventions. METHODS Persons with experience of a prenatal diagnosis of congenital heart defect in the fetus were interviewed after their participation in a yearlong collaborative research project (n = 9) aiming to explore relevant research questions and develop interventions for expectant parents with a recent prenatal diagnosis. Interviews were analyzed with qualitative content analysis. RESULTS Respondents acknowledged altruistic and personal value related to the collaboration. They valued the opportunity to contribute to future research so that the care of persons experiencing a prenatal diagnosis may be improved. Mixed feelings were described related to sharing and reliving experiences. While it had been emotionally difficult to relive a traumatic event, it also served as an opportunity to process experiences and psychologically adapt. Respondents with terminated pregnancies appreciated the possibility to meet peers, since it was difficult to find peers in everyday life and talk about their experiences with others. CONCLUSIONS Researchers who plan to collaborate with persons who have experience of a prenatal diagnosis should be mindful of the potential associated emotional experiences. The appreciation related to meeting peers calls attention to the need for studies that explore peer support.

Abstract
OBJECTIVES In selected single ventricle patients, a Glenn procedure (SV-Glenn) may be considered as definitive palliation. Either the patient is unsuited to progress to a Fontan circulation or a SV-Glenn circulation is preferred. This study aimed at describing the clinical course, and long-term mortality/morbidity of SV-Glenn patients. METHODS All SV-Glenn patients followed at the University Hospitals Leuven before May 2018 were included. Patients who underwent, or were awaiting, TCPC completion and those who underwent a Glenn in the setting of a biventricular circulation one-and-a-half repair (OAHR), were excluded. RESULTS Of 65 Glenn-only patients identified, 21 (32%) had OAHR, whereas 44 (68%) were SV-Glenn patients. Of SV-Glenn patients, 19 died within 6 months after the Glenn procedure. Of 25 SV-Glenn survivors, median age at Glenn was 6.3 (IQR 1.2-29.7) years. Eight were unsuited for TCPC completion; in 17 SV-Glenn was preferred over TCPC completion. Over a median follow-up time of 11 (IQR 3-18) years after the Glenn procedure, 5 (20%) patients died. At latest follow-up 10 (40%) had heart failure, 5 (20%) had atrial and 4 (16%) ventricular arrhythmias, 2 (8%) a thromboembolic event, 7 (28%) required pacemaker implantation, and 2 (8%) had infective endocarditis but none developed cirrhosis or protein-losing enteropathy. Mean saturation at latest follow-up was 87 ± 7%. CONCLUSION SV-Glenn patients represent a unique and heterogeneous patient population. Outcome was reasonable, although comorbidities, such as heart failure and arrhythmias were not uncommon. In SV-Glenn patients, 'classic' complications related to Fontan physiology, such as cirrhosis and protein-losing enteropathy, were absent.

Molecular and clinical studies in 107 Noonan syndrome affected individuals with PTPN11 mutations. BMC MEDICAL GENETICS 2020; 21:50. [PMID: 32164556 PMCID: PMC7068896 DOI: 10.1186/s12881-020-0986-5] [Citation(s) in RCA: 30] [Impact Index Per Article: 7.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/18/2019] [Accepted: 02/25/2020] [Indexed: 02/08/2023]
Abstract
Background Noonan syndrome (NS), an autosomal dominant developmental genetic disorder, is caused by germline mutations in genes associated with the RAS / mitogen-activated protein kinase (MAPK) pathway. In several studies PTPN11 is one of the genes with a significant number of pathogenic variants in NS-affected patients. Therefore, clinically diagnosed NS individuals are initially tested for pathogenic variants in PTPN11 gene to confirm the relationship before studying genotype–phenotype correlation. Methods Individuals (363) with clinically diagnosed NS from four hospitals in South India were recruited and the exons of PTPN11 gene were sequenced. Results Thirty-two previously described pathogenic variants in eight different exons in PTPN11 gene were detected in 107 patients, of whom 10 were familial cases. Exons 3, 8 and 13 had the highest number of pathogenic variants. The most commonly identified pathogenic variants in this series were in exon 8 (c.922A > G, c.923A > G), observed in 22 of the affected. Congenital cardiac anomalies were present in 84% of the mutation-positive cohort, the majority being defects in the right side of the heart. The most common facial features were downward-slanting palpebral fissures, hypertelorism and low-set posteriorly rotated ears. Other clinical features included short stature (40%), pectus excavatum (54%) and, in males, unilateral or bilateral cryptorchidism (44%). Conclusion The clinical features and mutational spectrum observed in our cohort are similar to those reported in other large studies done worldwide. This is the largest case series of NS-affected individuals with PTPN11 mutations described till date from India.

Abstract
Hypoplastic left heart syndrome is a constellation of malformations which result from the severe underdevelopment of any left-sided cardiac structures. Once considered to be universally fatal, the prognosis for this condition has tremendously improved over the past four decades since the work of William Norwood in the early 1980s. Today, a staged surgical approach is applied for palliating this distinctive cohort of patients, in which they undergo three operative procedures in the first 10 years of their life. Advancements in medical technologies, surgical techniques, and our growing experience in the management of HLHS have made survival into adulthood a possibility. Through this review, we present the different phases of the staged approach with primary focus on stage 1-its modifications, current technique, alternatives, and latest outcomes.

Abstract
The hypothesis that in utero exposures to low levels of trichloroethylene (TCE) may increase the risk of congenital heart defects (CHDs) in offspring remains a subject of substantial controversy within the scientific community due primarily to the reliance on an inconsistent and unreproducible experimental study in rats. To build on previous assessments that have primarily focused on epidemiological and experimental animal studies in developing conclusions, the objective of the current study is to conduct a systematic evaluation of mechanistic data related to in utero exposures to TCE and the development of CHDs. The evidence base was heterogeneous; 79 mechanistic datasets were identified, characterizing endpoints which ranged from molecular to organismal responses in seven species, involving both in vivo and in vitro study designs in mammalian and non-mammalian models. Of these, 24 datasets were considered reliable following critical appraisal using a study quality tool that employs metrics specific to the study type. Subsequent synthesis and integration demonstrated that the available mechanistic data: 1) did not support the potential for CHD hazard in humans, 2) did not support the biological plausibility of a response in humans based on organization via a putative adverse outcome pathway for valvulo-septal cardiac defects, and 3) were not suitable for serving as candidate studies in risk assessment. Findings supportive of an association were generally limited to in ovo chicken studies, in which TCE was administered in high concentration solutions via direct injection. Results of these in ovo studies were difficult to interpret for human health risk assessment given the lack of generalizability of the study models (including dose relevance, species-specific biological differences, variations in the construct of the study design, etc.). When the mechanistic data are integrated with findings from previous evaluations of human and animal evidence streams, the totality of evidence does not support CHDs as a critical effect in TCE human health risk assessment.

Abstract
PURPOSE Developmental delays are among the major morbidities of children with complex congenital heart disease. Parents of infants with complex congenital heart disease experience increased parenting stress levels, which can interfere with parenting processes during infancy. The current study examined associations between infant development and parenting stress in infants with complex congenital heart disease at six and twelve months of age. DESIGN AND METHODS A secondary analysis of data examined cross-sectional associations between infant's mental and psychomotor development and parenting stress, using general linear regression modeling (N = 75). Data were obtained from a larger prospective cohort study. RESULTS Mental development was negatively associated with the Parent Domain at six months, and with the Parent Domain and Total Stress at twelve months. Psychomotor development was not significantly associated with parenting stress at six and twelve months. CONCLUSIONS Parenting stress in parents of infant with complex congenital heart disease may be among the factors shaping the parent-child relationship during the first year of life, which plays an important role in infant development. A potential bidirectional relationship between parenting stress and infant development may fit a transactional model representing the phenomena. PRACTICE IMPLICATIONS Family interventions aiming to reshape illness perceptions may promote parental adaptive coping and productive parenting practices in populations at risk.

Abstract
Thymus, as a primary site of appropriate adaptive immunity formation, is an essential organ in face of a self-tolerance as well as a potential menace from impairment of body integrity. Due to vital selection processes during differentiation and maturation of T lymphocytes, control over cell survival and programmed cell death must be orchestrated in detail. Indeed, thymus is highly sensitive to wide spectrum of stressors that initiate acute structural changes. Hypoxia, one of the most common complications in congenital heart defects (CHDs) patients, provokes stress-induced thymus involution. Disrupted embryolonic development of thymus in association with congenital heart defects, may negatively affect physiological immune mechanisms. We propose that detailed analysis of thymic morphology could critically contribute to unveil the pathophysiology of diseases associated with disrupted adaptive immunity in children with heterogeneous congenital heart diseases.

Abstract
OBJECTIVES Firstly, to describe the outcome of a series of fetuses with Ebstein's anomaly (EA) and, secondly, to study the utility of different second-trimester echocardiographic parameters to predict fetal and neonatal mortality. METHODS 39 fetuses with EA diagnosed between 18 and 28 weeks of gestation were included. Fetal echocardiography included the cardiothoracic ratio (CTR); right atrial (RA) area index; displacement of the tricuspid valve (TV); tricuspid regurgitation; pulmonary artery; and ductus arteriosus flow characteristics. Additionally, 2 novel parameters were obtained: the relative RA area ratio (RA area/cardiac area) and the TV displacement index (TVDI, TV displacement distance/longi-tudinal diameter of the left ventricle). Correlation between the echocardiographic variables and the primary outcome of perinatal mortality or survival at 1 year of life was evaluated. RESULTS From the initial cohort, 8 cases were excluded due to complex congenital heart defects. Termination of pregnancy (TOP) was performed in 15 cases, and fetal death was diagnosed in 3 cases. In the live-born cohort of 13 patients, 4 died in the neonatal period, yielding a perinatal survival rate of 29 and 56%, respectively, after excluding TOP cases. Compared with survivors, nonsurvivors showed a significantly higher CTR (56.7 ± 16.2 vs. 42.6 ± 8.6; p = 0.04), relative RA area ratio (0.39 ± 0.13 vs. 0.25 ± 0.05; p = 0.01), and TVDI (0.62 ± 0.17 vs. 0.44 ± 0.12; p = 0.03) at diagnosis. The best model to predict perinatal mortality was obtained by using a scoring system which included the relative RA area ratio and TVDI (AUC 0.905 [95% CI 0.732-1.000]). CONCLUSIONS Fetuses with a relative RA area ratio ≥0.29 and TVDI ≥0.65 at the second trimester have the highest risk of dying in the perinatal stage.

scaRNA1 Levels Alter Pseudouridylation in Spliceosomal RNA U2 Affecting Alternative mRNA Splicing and Embryonic Development. Pediatr Cardiol 2020; 41:341-349.

Abstract
The heart is the first major organ to develop during embryogenesis and must receive proper spatiotemporal signaling for proper development. Failure of proper signaling between the first and second heart fields at twenty days gestation contributes to the generation of a congenital heart defect. The most common cyanotic congenital heart defect is tetralogy of Fallot (TOF) which requires surgical intervention in the first year of life. In right ventricular tissue of infants born with TOF, the levels of scaRNA1 are reduced and mRNA splicing is dysregulated. In this study, we investigate a method of quantifying pseudouridylation levels in relation to scaRNA1 levels in spliceosomal RNA U2 in three different groups of samples: right ventricular (RV) tissue of infants born with TOF versus RV tissue from normally developing infants, scaRNA1 knockdown in primary normal cardiomyocytes derived from normally developing infants, and scaRNA1 overexpression in primary cells derived from RV tissue from infants born with TOF. We hypothesize that the amount of pseudouridylation is dependent on scaRNA1 level, compromising spliceosomal function and therefore, contributing to the generation of a congenital heart defect. Our results revealed a statistically significant decrease of pseudouridylation levels in the right ventricular tissue of infants born with TOF compared to the controls. Knocking down the scaRNA1 levels in normal primary cardiomyocytes resulted in a statistically significant decrease of pseudouridylation. Finally, an overexpression of scaRNA1 in TOF primary cells resulted in an increase in pseudouridylation levels, but it did not achieve statistical significance. Our previous research provided an association between scaRNA levels, alternative splicing, and development. Here, we demonstrate that pseudouridylation levels in spliceosomal RNA U2 is dependent on the expression level of scaRNA1. Although further investigation is needed, we believe that scaRNA expression regulates biochemical modifications to spliceosomal RNAs, adjusting the fidelity of the spliceosome, allowing for controlled alternative splicing of mRNA that is important in embryonic development. If validated, this is an underappreciated mechanism that is critical for regulating proper embryonic development.

Abstract
INTRODUCTION Approved drugs for attention deficit hyperactivity disorder (ADHD) in Spain are methylphenidate, lisdexamphetamine, atomoxetine and guanfacine. Due to adverse cardiovascular effects, mainly increased blood pressure and heart rate, its use in patients with known or undiagnosed heart disease may be controversial. OBJECTIVE To obtain a consensus document from the Spanish Society of Paediatric Cardiology and Congenital Heart Diseases (SECPCC) and experts from other Agencies and Societies as a guide for the paediatric cardiologist and physicians who treat children and adolescents with ADHD. METHODOLOGY An analysis was performed on the bibliography and Clinical Practice Guidelines, technical data sheets approved by the Spanish Agency of Medicines and Health Devices, and the Spanish Ministry of Health Guidelines. A Working Group was formed, with a Coordinator, as well as members of the Clinical Cardiology Working Group and Arrhythmia Group of the SECPCC. This Group produced a preliminary document that was reviewed by a group of external experts and a group of internal experts of the SECPCC with a consensus being reached on the final document. RESULTS The recommendations of the SECPCC and the group of experts are presented on cardiovascular evaluation prior to treatment in children and adolescents with no known cardiovascular disease and with known cardiovascular disease. The recommendations of the SECPCC and the group of experts are also presented on the use of medications for ADHD in children and adolescents with cardiological symptoms with no evidence of heart disease, congenital heart disease, cardiomyopathy, Marfan syndrome and other aortic diseases, hypertension, and arrhythmias.

Abstract
BACKGROUND TAB2 is an activator of MAP 3 K7/TAK1, which is required for the IL-1 induced signal pathway. Microdeletions encompassing TAB2 have been detected in various patients with congenital heart defects (CHD), indicating that haploinsufficiency of TAB2 causes CHD. To date, seven variants within TAB2 were reported associated with CHD, only two of them are nonsense mutations. CASE PRESENTATION Here we describe a three-generation Chinese family that included five CHD patients with heart valvular defects, such as mitral or tricuspid valves prolapse or regurgitation, and aortic valve stenosis or regurgitation. Our proband was a pregnant woman presenting with mitral, tricuspid, and aortic defects; her first child experienced sudden cardiac death at the age of 2 years. Whole-exome sequencing of the proband revealed a novel nonsense variant in TAB2 (c.C446G, p.S149X), which results in the elimination of the majority of C-terminal amino acids of TAB2, including the critical TAK1-binding domain. The variant was identified in five affected patients but not in the eight unaffected family members using Sanger sequencing and was classified as "pathogenic" according to the latest recommendation on sequence variants laid out by the American College of Medical Genetics and Genomics and the Association for Molecular Pathology. CONCLUSION We described a family with CHD caused by a novel TAB2 nonsense mutation. Our study broadens the mutation spectrum of TAB2; to the best of our knowledge, this is the first report of a pathogenic mutation within TAB2 in a Chinese population.

Abstract
Background The evidence regarding patient related outcomes in children with infrequent congenital heart defects (I-CHD) is very limited. We sought to measure quality of life (QoL) in children with I-CHD, and secondarily, to describe QoL changes after one-year of follow-up, self-reported by children and through their caregivers’ perspective. Methods We assembled a cohort of children diagnosed with an I-CHD in a cardiovascular referral center in Colombia, between August 2016 and September 2018. At baseline and at one-year follow-up, a clinical psychology assessment was performed to establish perception of QoL. The Pediatric Quality of Life Inventory (PedsQL) 4.0 scale was used in both general and cardiac modules for patients and for their caregivers. We used a Mann-Whitney U test to compare scores for general and cardiac modules between patients and caregivers, while a Wilcoxon test was used to compared patients’ and caregivers’ baseline and follow-up scores. Results are presented as median and interquartile range. Results To date, QoL evaluation at one-year follow-up has been achieved in 112/157 patients (71%). Self-reported scores in general and cardiac modules were higher than the QoL perceived through their caregivers, both at baseline and after one-year of follow-up. When compared, there was no statistically significant difference in general module scores at baseline between patients (median = 74.4, IQR = 64.1–80.4) and caregivers scores (median = 68.4, IQR = 59.6–83.7), p = 0.296. On the contrary, there was a statistical difference in baseline scores in the cardiac module between patients (median = 79.6, IQR = 69.7–87.4) and caregivers (median = 73.6, IQR = 62.6–84.3), p = 0.019. At one-year of follow-up, scores for the general module between patients (median = 72.8, IQR = 59.2–85.9) and caregivers (median = 69.9, IQR = 58.1–83.7) were not statistically different (p = 0.332). Finally, a significant difference was found for cardiac module scores between patient (median = 75.0, IQR = 67.1–87.1) and caregivers (median = 73.1, IQR = 59.5–83.8), p = 0.034. Conclusions QoL in children with I-CHD can be compromised. However, children have a better perception of their QoL when compared with their caregivers’ assessments. To provide high-quality care, besides a thorough clinical evaluation, QoL directly elicited by the child should be an essential aspect in the integral management of I-CHD.

Abstract
The purpose of this study was to investigate parent reports of quality of life for their very young children with congenital heart defects (CHD) and to compare their scores to previously published data. Parents of children 1-3 years old with CHD or innocent heart murmurs completed the Pediatric Quality of Life Inventory (PedsQL) core, cardiac, and family impact modules. Multivariable regression analyses assessed the impact of age, sex, family income, and CHD treatment history (study group) on PedsQL scores. Correlations between family impact and core/cardiac modules were examined. PedsQL scores were compared to healthy norms. 140 parents of young children participated within four study groups: CHD no treatment (n = 44), CHD treatment without bypass (n = 26), CHD treatment with bypass (n = 42) ,and innocent heart murmurs (n = 28). Male sex was associated with higher core (F = 4.16, p = 0.04, σ2 = .03) and cardiac quality of life (F = 4.41, p = .04, σ2 = 0.04). Higher family income was associated with higher family quality of life (F = 8.89, p < .01, σ2 = 0.13). Parents of children with innocent heart murmurs and children with CHD not requiring treatment had higher core quality of life compared to young healthy children. Cardiac-related quality of life scores were associated with family impact (r = 0.68) and core module (r = 0.63) quality of life scores. Parents of very young children with CHD report good quality of life for their children and families. Quality of life exceeds in children with innocent murmurs or CHD not requiring repair. Parents report a lower quality of life among girls, and lower family quality of life is associated with lower family income.
