Preconception underweight and the risk of offspring congenital heart diseases in young pregnant women: Evidence from the China Birth Cohort Study.

OBJECTIVE: Maternal obesity is a highly suggestive risk factor of offspring congenital heart diseases (CHD). However, the risk of offspring CHD associated with maternal underweight has rarely been mentioned. Therefore, this study aimed to explore the effect of preconception underweight on offspring CHD. METHODS: From November 2017 to August 2021, 132 386 pregnant women were enrolled in a birth cohort study in China in early pregnancy, and completed follow-up until delivery (or miscarriage/termination). Offspring CHD was diagnosed by prenatal ultrasound examination in both live births and stillbirths. Log-binomial regression and restricted cubic spline were used to estimate the risk of offspring CHD associated with preconception body mass index (BMI). A generalized additive model was used to explore the modification effect of maternal age on the association between preconception BMI and offspring CHD. RESULTS: A total of 129 096 pregnant women were included in the analysis. The incidence of CHD in the underweight, normal weight, overweight, and obesity groups were 117/17 313 (0.68%), 556/85 695 (0.65%), 128/19 936 (0.64%), 47/6152 (0.76%), respectively. Both underweight and obesity before pregnancy marginally increased the risk of offspring CHD. The association between preconception BMI and offspring CHD varied by maternal age, with low preconception BMI associated with a significantly higher risk of offspring CHD in women <24 years (RR 2.32, 95% CI: 1.07-5.01 for 17 vs 21 kg/m2). CONCLUSION: Preconception underweight was associated with an increased risk of offspring CHD in young pregnant women. Therefore, weight gain is important to prevent offspring CHD, especially for young women with low preconception BMI.

Down syndrome and postoperative hemodynamics in patients undergoing surgery for congenital cardiac communications.

Although Down syndrome (DS) is considered a risk factor for hemodynamic instabilities (mainly pulmonary hypertension-PH) following surgery for congenital cardiac communications, many DS patients do surprising well postoperatively. We prospectively analyzed perioperative factors for a possible correlation with post-cardiopulmonary bypass (CPB) inflammatory reaction and postoperative PH in pediatric subjects. Sixty patients were enrolled (age 3 to 35 months), 39 of them with DS. Clinical and echocardiographic parameters (anatomical and hemodynamic) were computed preoperatively. Pulmonary and systemic mean arterial pressures (PAP and SAP) were assessed invasively intra and postoperatively. Immediate postoperative PAP/SAP ratio (PAP/SAPIPO) and the behavior of pressure curves were selected as primary outcome. Serum levels of 36 inflammatory proteins were measured by chemiluminescence preoperatively and 4 h post CPB. Of all factors analyzed, peripheral oxygen saturation (O2Sat, bedside assessment) was the only preoperative predictor of PAP/SAPIPO at multivariate analysis (p = 0.007). Respective values in non-DS, DS/O2Sat ≥ 95% and DS/O2Sat < 95% subgroups were 0.34 (0.017), 0.40 (0.027) and 0.45 (0.026), mean (SE), p = 0.004. The difference between non-DS and DS groups regarding postoperative PAP curves (upward shift in DS patients, p = 0.015) became nonsignificant (p = 0.114) after adjustment for preoperative O2Sat. Post-CPB levels of at least 5 cytokines were higher in patients with O2Sat < 95% versus those at or above this level, even within the DS group (p < 0.05). Thus, a baseline O2Sat < 95% representing pathophysiological phenomena in the airways and the distal lung, rather than DS in a broad sense, seems to be associated with post-CPB inflammation and postoperative PH in these patients.

KidsTUMove-A Holistic Program for Children with Chronic Diseases, Increasing Physical Activity and Mental Health.

The prevalence of chronic diseases in children and adolescents has risen alarmingly worldwide. Diseases such as asthma, diabetes, obesity, mental disorders, and congenital heart defects are increasingly affecting the lives of children and pose significant challenges for the healthcare system. Physical activity plays a crucial role in preventing and treating these diseases. Numerous studies have shown that regular exercise improves physical performance, increases well-being, and leads to better health in the long term. Specially tailored sports programs that meet the individual needs and abilities of the children and adolescents affected are particularly important. The KidsTUMove project addresses this by developing tailored exercise programs for children with chronic diseases' specific needs, medical conditions, and physical abilities. Therefore, it closes the gap in care provision and can thus sustainably improve the health prospects of these children and adolescents. KidsTUMove is positioned to make a significant impact on the lives of affected children across Europe. Promotion of such programs should therefore be an integral part of future health strategies.

Right-Sided Aortic Arch: A Computed Tomography Angiography Investigation, A Systematic Review with Meta-Analysis.

Background/Objectives: The right-sided aortic arch (RAA) is an uncommon variation of the aortic arch (AA), characterized by the aorta crossing over the right main bronchus. In the RAA, the descending aorta can be found on either the right or left side of the spine. The current study comprises a comprehensive retrospective computed tomography angiography (CTA) investigation into the prevalence of the RAA within the Greek population. Additionally, we will conduct a systematic review and meta-analysis to elucidate both common and rare morphological variants of the RAA. This research is significant as it sheds light on the prevalence and characteristics of the RAA in a specific population, providing valuable insights for clinical practice. Methods: Two hundred CTAs were meticulously investigated for the presence of a RAA. In addition, the PubMed, Google Scholar, and Scopus online databases were thoroughly searched for studies referring to the AA morphology. The R programming language and RStudio were used for the pooled prevalence meta-analysis, while several subgroup analyses were conducted. Results: Original study: A unique case of 200 CTAs (0.5%) was identified with an uncommon morphology. The following branches emanated from the RAA under the sequence: the right subclavian artery (RSA), the right common carotid artery (RCCA), the left common carotid artery (LCCA), and the left vertebral artery (LVA) in common origin with the aberrant left subclavian artery (ALSA). The ALSA originated from a diverticulum (of Kommerell) and followed a retroesophageal course. Systematic Review and Meta-Analysis: Sixty-two studies (72,187 total cases) met the inclusion criteria. The pooled prevalence of the RAA with a mirror-image morphology was estimated at 0.07%, and the RAA with an ALSA was estimated at <0.01%. Conclusions: AA anomalies, specifically the RAA, raise clinical interest due to their coexistence with developmental heart anomalies and possible interventional complications. Congenital heart anomalies, such as the Tetralogy of Fallot and patent foramen ovale, coexisted with RAA mirror-image morphology.

Beyond the heart: Cognitive and verbal outcomes in Arab children with congenital heart diseases.

BACKGROUND: This study investigates how congenital heart diseases (CHD) characteristics and interventions affect cognitive and verbal skills in Arab children, while also uncovering previously unexplored connections between these skills and the quality of life (QoL) scores as perceived by both children and parents. METHODS: A cross-sectional study was conducted in Jordan, involving 62 children with CHD aged 6-16. Data were collected through standardized intelligence tests (namely The Raven's Progressive Matrices Test and The Wechsler Intelligence Scale for Children) and QoL assessments. RESULTS: Sex, disease severity, cyanosis, CHD defect status, conducted operations, and types of interventions did not significantly influence cognitive scores. However, a significant difference was observed in Wechsler's scores between cyanotic and non-cyanotic children (p < .01) and between severe and moderate cases (p = .01). Further, a significant positive correlation was identified between Wechsler's Scores and QoL reported by parents (r = 0.33, p < .01). This correlation was particularly pronounced in the social and school functioning dimensions of QoL. CONCLUSIONS: This study highlights the need for personalized care approaches for children with CHDs based on their individual characteristics. While cognitive abilities did not directly correlate with children's QoL reports, a significant positive correlation between verbal skills and QoL reported by parents underscores the importance of effective communication in assessing a child's overall well-being. Future research should further examine the cognitive development in this population, employing neurocognitive investigations and longitudinal studies to gain a deeper understanding of their cognitive profiles and trajectories.

Impact of preoperative respiratory distress on outcomes of slide tracheoplasty.

OBJECTIVES: Children with congenital tracheal stenosis born in the developing world face a high risk of mortality due to limited access to proper treatment. Patients who required preoperative respiratory support were suspected to have poor survival after slide tracheoplasty; however, this was not clearly demonstrated in the previous studies. This study aims to investigate the impact of preoperative respiratory conditions on outcomes of slide tracheoplasty. METHODS: From 2016 to 2022, children who underwent slide tracheoplasty were retrospectively reviewed. Patients with respiratory distress requiring emergency operations (group A) were compared with patients in stable condition who were scheduled for surgery (group B). RESULTS: Perioperative results revealed that group A (n = 43) had a longer bypass time (P < 0.001), operation time (P = 0.01), postoperative ventilation time (P < 0.001) and length of intensive care unit stay (P = 0.00125) than group B (n = 60). The early mortality rate was 7.8%, and the actuarial 5-year survival rate was 85.3%. The cumulative incidence test revealed that group A was highly significant for overall mortality [sudistribution (SHR) 4.5; 95% confidence interval (CI) 1.23-16.4; P = 0.023]. Risk factors for overall mortality were prolonged postoperative ventilation time (hazard ratio 3.86; 95% CI 1.20-12.48; P = 0.024), bronchial stenosis (hazard ratio 5.77; 95% CI 1.72-19.31; P = 0.004), and preoperative tracheal mucositis (hazard ratio 5.67; 95% CI 1.51-21.31; P = 0.01). Four patients needed reintervention during a follow-up of 28.4 months (interquartile range 15.3-47.3). CONCLUSIONS: Preoperative respiratory distress negatively affected the outcomes of patients who required slide tracheoplasty. Therefore, early detection of congenital tracheal stenosis and aggressive slide tracheoplasty are crucial and obligatory to enhance long-term survival in this lethal congenital airway disease.

A Case of Double Inlet Left Ventricle in a 63-Year-Old Female Patient.

This case report describes the medical history and presentation of an elderly patient who was born with single ventricle physiology, an anomaly that is both unique and complex. Patients with single ventricle cardiac anomalies may be susceptible to life-threatening complications. However, advances in medical treatment and understanding have allowed for clinicians to develop surgical and medical interventions to treat patients with univentricular cardiac defects. This case is unique in the sense that the patient has been able to demonstrate remarkable adaptability to this condition and have a sustained life with little intervention. This report serves to explore the pathophysiology of this condition as well as highlight the human body's astounding resilience to configure itself to abnormal conditions. The patient's presentation will be discussed as well as diagnostics and management utilized by the care providers. Despite its rare occurrence, understanding the manifestations of this complex cardiac abnormality can allow future providers to improve the prognosis and outcomes of patients born with a single ventricle.

Children with Congenital Heart Diseases Exhibit Altered Deep Gray Matter Structures.

BACKGROUND AND OBJECTIVES: Children with congenital heart diseases (CHDs) have an increased risk of developing neurologic deficits, even in the absence of apparent brain pathology. The aim of this work was to compare quantitative macro- and microstructural properties of subcortical gray matter structures of pediatric CHD patients with normal appearing brain magnetic resonance imaging to healthy controls. METHODS: We retrospectively reviewed children with coarctation of the aorta (COA) and hypoplastic left heart syndrome (HLHS) admitted to our hospital. We identified 24 pediatric CHD patients (17 COA, 7 HLHS) with normal-appearing brain MRI. Using an atlas-based approach, the volume and apparent diffusion coefficient (ADC) were determined for the thalamus, caudate, putamen, pallidum, hippocampus, amygdala, nucleus accumbens, cerebral white matter, cerebral cortex, and brainstem. Multivariate statistics were used to compare the extracted values to reference values from 100 typically developing children without any known cardiac or neurological diseases. RESULTS: Multivariate analysis of covariance using the regional ADC and volume values as dependent variables and age and sex as co-variates revealed a significant difference between pediatric CHD patients and healthy controls (p < 0.001). Post-hoc comparisons demonstrated significantly reduced brain volumes in most subcortical brain regions investigated and elevated ADC values in the thalamus for children with CHD. No significant differences were found comparing children with COA and HLHS. CONCLUSIONS: Despite normal appearing brain MRI, children with CHD exhibit wide-spread macro-structural and regional micro-structural differences of subcortical brain structures compared to healthy controls, which could negatively impact neurodevelopment, leading to neurological deficits in childhood and beyond.

Clinical implications of dextrocardia based on four visceroatrial situs studies.

BACKGROUND: Previous studies on congenital heart diseases (CHD) associated with dextrocardia were based on selective patient databases and did not reflect the full spectrum of dextrocardia in the general population. Additionally, these studies had complex classification and presentation. Nor did these studies elaborate on the distribution of the associated CHD's complexity, the various segmental connections, and associated CHD among the four visceroatrial situs. METHODS: We retrospectively reviewed the medical records of 211 children with primary dextrocardia. We used a segmental approach to diagnose CHD. We then analyzed and compared the distribution of the above-mentioned issues among the four visceroatrial situs. RESULTS: Dextrocardia occurred most commonly with situs inversus (52.6%), followed by situs solitus (28.4%), asplenia (17.1%), and polysplenia (1.9%). Although some patients had a structurally normal heart (22.7%) or they were associated with simple CHD (17.5%), most patients had complex CHD (59.7%) consisting of a single ventricle (34.6%) or conotruncal anomaly (25.1%) (double-outlet right ventricle [7.6%], corrected transposition of the great arteries [6.2%], complete transposition of the great arteries [5.7%], tetralogy of Fallot [4.7%], etc.). Situs inversus or polysplenia had a higher prevalence of a structurally normal heart or associated with simple CHD, two patent atrioventricular (AV) valves connections, and biventricular AV connections. Situs solitus or asplenia had a higher prevalence of associated complex CHD, common AV valve connection, univentricular AV connection, pulmonary outflow tract obstruction, and anomalous pulmonary venous drainage. CONCLUSION: Our study finds that situs inversus is the most common visceroatrial situs in dextrocardia. Although some patients had a structurally normal heart or were associated with simple CHD, most patients have associated complex CHD consisting of a single ventricle or conotruncal anomaly. Dextrocardia is associated with a higher incidence of complex CHD in situs solitus and asplenia groups than in situs inversus and polysplenia groups.

Surgical Repair of Atrial Septal Defect in a Patient with 3-Methylcrotonyl-CoA Carboxylase Deficiency.

3-Methylcrotonyl-CoA carboxylase (3-MCC) deficiency is a rare autosomal recessive disease of leucine catabolism. 3-MCC deficiency may lead to metabolic decompensation under stress; however, outcomes of elective surgery requiring cardiopulmonary bypass (CPB) are unknown. We report a 4-year-old girl with asymptomatic 3-MCC deficiency and atrial septal defect (ASD) who's undergone surgical ASD repair under CPB. She was otherwise normal developmentally and medically. Although patients with 3-MCC may face metabolic crises, the ASD repair under CPB was uneventful.

Efficiency of copy number variation sequencing combined with karyotyping in fetuses with congenital heart disease and the following outcomes.

BACKGROUND: Both copy number variant-sequencing (CNV-seq) and karyotype analysis have been used as powerful tools in the genetic aetiology of fetuses with congenital heart diseases (CHD). However, CNV-seq brings clinicians more confusions to interpret the detection results related to CHD with or without extracardiac abnormalities. Hence, we conducted this study to investigate the clinical value of CNV-seq in fetuses with CHD. RESULTS: A total of 167 patients with fetal CHD including 36 single CHD (sCHD), 41 compound CHD (cCHD) and 90 non-isolated CHD (niCHD) were recruited into the study. 28 cases (16.77%, 28/167) were revealed with chromosomal abnormalities at the level of karyotype. The pathogenic detection rate (DR) of CNV-seq (23.17%, 19/82) was higher than that of karyotyping (15.85%, 13/82) in 82 cases by CNV-seq and karyotyping simultaneously. The DR of pathogenic copy number variations (PCNVs) (31.43%) was higher in niCHD subgroup than that in sCHD and cCHD (9.52% and 23.08%). Conotruncal defect (CTD) was one of the most common heart malformations with the highest DR of PCNVs (50%) in 7 categories of CHD. In terms of all the pregnancy outcomes, 67 (40.12%) cases were terminated and 100 (59.88%) cases were live neonates. Only two among 34 cases with a pathogenic genetic result chose to continue the pregnancy. CONCLUSIONS: CNV-seq combined with karyotyping is a reliable and accurate prenatal technique for identifying pathogenic chromosomal abnormalities associated with fetal CHD with or without extracardiac abnormalities, which can assist clinicians to perform detailed genetic counselling with regard to the etiology and related outcomes of CHD.

Congenital heart diseases (CHDs) and forensic investigations: Searching for the cause of death.

Congenital Heart Diseases (CHDs) are a group of structural abnormalities or defects of the heart that are present at birth. CHDs could be connected to sudden death (SD), defined by the WHO (World Health Organization) as "death occurring within 24 h after the onset of the symptoms" in an apparently "healthy" subject. These conditions can range from relatively mild defects to severe, life-threatening anomalies. The prevalence of CHDs varies across populations, but they affect millions of individuals worldwide. This article aims to discuss the post-mortem investigation of death related to CHDs, exploring the forensic approach, current methodologies, challenges, and potential advancements in this challenging field. A further goal of this article is to provide a guide for understanding these complex diseases, highlighting the pivotal role of autopsy, histopathology, and genetic investigations in defining the cause of death, and providing evidence about the translational use of autopsy reports. Forensic investigations play a crucial role in understanding the complexities of CHDs and determining the cause of death accurately. Through collaboration between medical professionals and forensic experts, meticulous examinations, and analysis of evidence, valuable insights can be gained. These insights not only provide closure to the families affected but also contribute to the prevention of future tragedies.

Art or Artifact: Evaluating the Accuracy, Appeal, and Educational Value of AI-Generated Imagery in DALL·E 3 for Illustrating Congenital Heart Diseases.

Artificial Intelligence (AI), particularly AI-Generated Imagery, has the potential to impact medical and patient education. This research explores the use of AI-generated imagery, from text-to-images, in medical education, focusing on congenital heart diseases (CHD). Utilizing ChatGPT's DALL·E 3, the research aims to assess the accuracy and educational value of AI-created images for 20 common CHDs. In this study, we utilized DALL·E 3 to generate a comprehensive set of 110 images, comprising ten images depicting the normal human heart and five images for each of the 20 common CHDs. The generated images were evaluated by a diverse group of 33 healthcare professionals. This cohort included cardiology experts, pediatricians, non-pediatric faculty members, trainees (medical students, interns, pediatric residents), and pediatric nurses. Utilizing a structured framework, these professionals assessed each image for anatomical accuracy, the usefulness of in-picture text, its appeal to medical professionals, and the image's potential applicability in medical presentations. Each item was assessed on a Likert scale of three. The assessments produced a total of 3630 images' assessments. Most AI-generated cardiac images were rated poorly as follows: 80.8% of images were rated as anatomically incorrect or fabricated, 85.2% rated to have incorrect text labels, 78.1% rated as not usable for medical education. The nurses and medical interns were found to have a more positive perception about the AI-generated cardiac images compared to the faculty members, pediatricians, and cardiology experts. Complex congenital anomalies were found to be significantly more predicted to anatomical fabrication compared to simple cardiac anomalies. There were significant challenges identified in image generation. Based on our findings, we recommend a vigilant approach towards the use of AI-generated imagery in medical education at present, underscoring the imperative for thorough validation and the importance of collaboration across disciplines. While we advise against its immediate integration until further validations are conducted, the study advocates for future AI-models to be fine-tuned with accurate medical data, enhancing their reliability and educational utility.

The effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases: objectives and design of a randomized controlled trial.

BACKGROUND: Understanding the severity of the disease from the parents' perspective can lead to better patient outcomes, improving both the child's health-related quality of life and the family's quality of life. The implementation of 3-dimensional (3D) modeling technology in care is critical from a translational science perspective. AIM: The purpose of this study is to determine the effect of 3D modeling on family quality of life, surgical success, and patient outcomes in congenital heart diseases. Additionally, we aim to identify challenges and potential solutions related to this innovative technology. METHODS: The study is a two-group pretest-posttest randomized controlled trial protocol. The sample size is 15 in the experimental group and 15 in the control group. The experimental group's heart models will be made from their own computed tomography (CT) images and printed using a 3D printer. The experimental group will receive surgical simulation and preoperative parent education with their 3D heart model. The control group will receive the same parent education using the standard anatomical model. Both groups will complete the Sociodemographic Information Form, the Surgical Simulation Evaluation Form - Part I-II, and the Pediatric Quality of Life Inventory (PedsQL) Family Impacts Module. The primary outcome of the research is the average PedsQL Family Impacts Module score. Secondary outcome measurement includes surgical success and patient outcomes. Separate analyses will be conducted for each outcome and compared between the intervention and control groups. CONCLUSIONS: Anomalies that can be clearly understood by parents according to the actual size and dimensions of the child's heart will affect the preoperative preparation of the surgical procedure and the recovery rate in the postoperative period.

Preventive strategies in paediatric cardiovascular surgery: impact on surgical site infections and beyond.

BACKGROUND: Surgical management of congenital heart disease (CHD) has increased worldwide, but healthcare-associated infections (HAIs) can threaten these efforts. AIM: To analyse the incidence of HAI, the impact of preventive interventions, and microbiological profiles in a paediatric cardiovascular surgery programme. METHODS: Cohort study including children aged <12 years with CHD who underwent cardiovascular surgery between 2010 and 2021 in Medellín, Colombia (a middle-income setting). Data were collected from medical and laboratory records and infection control programme databases. Impact of various preventive interventions was assessed using a Poisson model. P < 0.05 was considered statistically significant. FINDINGS: A total of 2512 surgeries were analysed. Incidence of surgical site infection (SSI) was 5.9%, followed by central line-associated bloodstream infection (CLABSI; 4.7%), catheter-associated urinary tract infection (CAUTI; 2.2%), and ventilator-associated pneumonia (VAP; 1.4%). Most of the strategies focused on preventing SSI, resulting in a reduction from 9.5% in 2010 to 3.0% in 2021 (P = 0.030). Antibiotic prophylaxis based on patient weight and continuous infusion had an impact on reducing SSI (RR: 0.56; 95% CI: 0.32-0.99). Vacuum-assisted closure (VAC) in clean wounds reduced 100% of infections. No significant risk reduction was observed for other HAI with the implemented interventions. CONCLUSION: Preventive strategies effectively reduced SSI but no other infections, emphasizing the need for targeted approaches to address a broader spectrum of HAI successfully.

2024 SIAC guidelines on cardiorespiratory rehabilitation in pediatric patients with congenital heart disease.

The 2024 Interamerican Society of Cardiology (SIAC) guidelines on cardiorespiratory rehabilitation (CRR) in pediatric patients with congenital heart disease aim to gather and evaluate all relevant evidence available on the topic to unify criteria and promote the implementation of CRR programs in this population in Latin America and other parts of the world. Currently, there is no unified CRR model for the pediatric population. Consequently, our goal was to create these CRR guidelines adapted to the characteristics of congenital heart disease and the physiology of this population, as well as to the realities of Latin America. These guidelines are designed to serve as a support for health care workers involved in the care of this patient group who wish to implement a CRR program in their workplace. The guidelines include an easily reproducible program model that can be implemented in any center. The members of this Task Force were selected by the SIAC on behalf of health care workers dedicated to the care of pediatric patients with congenital heart disease. To draft the document, the selected experts performed a thorough review of the published evidence.

Exposure to Endocrine-Disrupting Chemicals and Congenital Heart Diseases: The Pooled Results Based on the Current Evidence.

The relationships between maternal exposure to endocrine-disrupting chemicals (EDCs) and congenital heart diseases (CHD) are not elucidated yet. The exposure levels of EDCs are generally estimated based on self-reported questionnaires or occupational exposure evaluations in the literature. Therefore, a study based on epidemiological data from human biospecimens is required to provide stronger evidence between maternal exposure to EDC and CHD. Embase, Pubmed, Scopus, and the Cochrane Library databases were searched for related research which provided risk estimates regarding the relationships between maternal EDC exposure and CHD in human offspring. Baseline characteristics and outcomes of CHD were extracted from each included study. Odds ratios (ORs) with 95% confidence intervals (CIs) were pooled to calculate the overall estimates of CHD. Subgroup and meta-regression analyses were performed to identify the sources of heterogeneity. Bootstrapping techniques were used in analyses where several studies originated from a similar population. A total of seventeen studies were involved in the meta-analyses. Maternal EDC exposure was significantly related to CHD in offspring (OR 2.15; 95%CI 1.64 to 2.83). EDC exposure was significantly associated with septal defects (OR 2.34; 95%CI 1.77 to 3.10), conotruncal defects (OR 2.54; 95%CI 1.89 to 3.43), right ventricular outflow tract obstruction (OR 2.65; 95%CI 1.73 to 4.07), left ventricular outflow tract obstruction (OR 3.58; 95%CI 2.67 to 4.79), anomalous pulmonary venous return (OR 2.31; 95%CI 1.34 to 4.00), and other heart defects (OR 2.49; 95%CI 1.75 to 3.54). In addition, maternal exposure to heavy metals, which included lead (OR 2.19; 95%CI 1.29 to 3.71), cadmium (OR 1.81; 95%CI 1.28 to 2.56), mercury (OR 2.23; 95%CI 1.13 to 4.44), and manganese (OR 2.65; 95%CI 1.48 to 4.74), increased risks for CHD significantly. In conclusion, based on the latest evidence, maternal EDC exposure may increase CHD risks in human offspring, especially in heavy metal exposure conditions.

The Outcomes of Cardiac Surgery in Children With DiGeorge Syndrome in a Single Center Experience: A Retrospective Cohort Study.

Background DiGeorge syndrome, a common genetic microdeletion syndrome, is associated with multiple congenital anomalies, including congenital cardiac diseases. This study aims to identify the short and midterm outcomes of cardiac surgery performed on children with DiGeorge syndrome. Methods A retrospective cohort study was conducted between the period of 2018-2022, which included children divided into two groups with a 1:2 ratio. Group one included DiGeorge syndrome patients who were diagnosed using fluorescence in situ hybridization (FISH). Group two included the control group of patients who were clear of genetic syndromes. The two groups were matched based on similar cardiac surgery, age of surgery, and Risk Adjustment in Congenital Heart Surgery (RACHS-1) score. The two groups were compared based on the demographical data and postoperative complications. Results The study consisted of 81 children; 27 were DiGeorge syndrome patients, and 54 were in the control group. DiGeorge syndrome patients showed an increase in mechanical ventilation duration (p=0.0047), intensive care unit (ICU) length of stay (p=0.0012), and hospital length of stay (p=0.0391). Moreover, they showed an increased risk for bacteremia (p=0.0414), ventilator-associated pneumonia (VAP; p=0.0036), urinary tract infections (UTI; p=0.0064), and surgical site infection (SSI; p≤0.0001). They were also more susceptible to postoperative seizures (p=0.0049). Furthermore, patients with DiGeorge syndrome had a higher prevalence of congenital renal anomalies. However, there was no mortality in either group.  Conclusion This study shows a variability in the postoperative outcomes between the two groups. The study demonstrates that patients with DiGeorge syndrome have higher risks of infections and longer hospital stay during the postoperative period. Further research with a larger sample is needed to confirm our findings.

The mechanics of congenital heart disease: from a morphological trait to the functional echocardiographic evaluation.

Advances in pediatric cardiac surgery have resulted in a recent growing epidemic of children and young adults with congenital heart diseases (CHDs). In these patients, congenital defects themselves, surgical operations and remaining lesions may alter cardiac anatomy and impact the mechanical performance of both ventricles. Cardiac function significantly influences outcomes in CHDs, necessitating regular patient follow-up to detect clinical changes and relevant risk factors. Echocardiography remains the primary imaging method for CHDs, but clinicians must understand patients' unique anatomies as different CHDs exhibit distinct anatomical characteristics affecting cardiac mechanics. Additionally, the use of myocardial deformation imaging and 3D echocardiography has gained popularity for enhanced assessment of cardiac function and anatomy. This paper discusses the role of echocardiography in evaluating cardiac mechanics in most significant CHDs, particularly its ability to accommodate and interpret the inherent anatomical substrate in these conditions.
