The Connection Between Anatomical Substrate and Clinical Severity in Fetal Ebstein Anomaly.

Ebstein anomaly (EA) is a rare congenital heart defect characterized by abnormal development of the tricuspid valve (TV) and right ventricular myocardium. This study documents 2 dramatic cases of fetal EA characterized by hydrops and cardiomegaly, leading to intrauterine or early neonatal death. These clinical outcomes were associated with morphological abnormalities including severe tricuspid regurgitation, unguarded TV orifice, pulmonary atresia, and flattened right ventricular myocardium. This study highlights that these adverse anatomical features may result in unfavorable clinical outcomes in fetal EA. While timely identification of such features by prenatal ultrasound is crucial for providing accurate prognostic stratification and guiding treatment decisions, fetopsy may be necessary to discern EA among the spectrum of right-heart anomalies.

Mental Health Care for Children with Heart Disease and Their Families: Practical Approaches and Considerations for the Pediatric and Pediatric Cardiology Clinician.

Mental health conditions are a common comorbidity among children living with heart disease. Children with congenital heart disease are more likely to have a mental health condition than their unaffected peers or peers with other chronic illnesses, and mental health risk persists across their lifetime. While poorer mental health in adults with congenital heart disease is associated with worse overall health outcomes, the association between mental health and cardiac outcomes for children with heart disease remains unknown. Despite this, it is suspected that mental health conditions go undiagnosed in children with heart disease and that many affected children and adolescents do not receive optimal mental health care. In this article, we review mental health in congenital heart disease across the lifespan, across domains of care, and across diagnoses. Further directions to support mental health care for children and adolescents with heart disease include practical screening and access to timely referral and mental health resources.

The Ongoing Relationship Between Offspring Congenital Heart Disease and Preeclampsia Across Pregnancies.

Background: Prior literature has described an association between preeclampsia and offspring congenital heart disease (CHD), while suggesting there may be a stronger relationship in individuals with early preeclampsia. Objectives: The authors sought to explore the relationship between offspring CHD and preeclampsia among pregnancies in a population-based study. Methods: Retrospective cohort study all singleton pregnancies delivered in the state of California 2000 to 2012. We included singleton births with gestational ages of 23 to 42 weeks and excluded pregnancies complicated by pre-existing diabetes or identified fetal chromosomal anomalies. We used multivariable logistic regression to estimate ORs for associations between offspring CHD and preeclampsia. Further subanalyses examined the relationships in deliveries <34 weeks and >34 weeks to analyze if there was a difference according to timing of preeclampsia development. Results: Preeclampsia was strongly associated with offspring CHD (aOR: 1.38; 99% CI: 1.29-1.49) in the same pregnancy. Among patients with preeclampsia in the index pregnancy, there was an increased risk of fetal CHD in the subsequent pregnancy (aOR: 1.39; 99% CI: 1.20-1.61). Among patients with offspring CHD in the index pregnancy, there was an increased risk of preeclampsia in the subsequent pregnancy (aOR: 1.39; 99% CI: 1.15-1.68). In all 3 analyses, results remained significant when stratified by <34 weeks and ≥34 weeks. Conclusions: Our findings suggest a need for further investigation into the etiology of preeclampsia and its relationship to embryologic development of cardiovascular structures.

The Evolving Role of Genetic Evaluation in the Prenatal Diagnosis and Management of Congenital Heart Disease.

Congenital heart disease (CHD) is increasingly diagnosed prenatally and the ability to screen and diagnose the genetic factors involved in CHD have greatly improved. The presence of a genetic abnormality in the setting of prenatally diagnosed CHD impacts prenatal counseling and ensures that families and providers have as much information as possible surrounding perinatal management and what to expect in the future. This review will discuss the genetic evaluation that can occur prior to birth, what different genetic testing methods are available, and what to think about in the setting of various CHD diagnoses.

Risk Factors for Death or Transplant After Stage 2 Palliation for Single Ventricle Heart Disease.

Background: For infants with single ventricle heart disease, the time after stage 2 procedure (S2P) is believed to be a lower risk period compared with the interstage period; however, significant morbidity and mortality still occur. Objectives: This study aimed to identify risk factors for mortality or transplantation referral between S2P surgery and the first birthday. Methods: Retrospective cohort analysis of infants in the National Pediatric Cardiology Quality Improvement Collaborative who underwent staged single ventricle palliation from 2016 to 2022 and survived to S2P. Multivariable logistic regression and classification and regression trees were performed to identify risk factors for mortality and transplantation referral after S2P. Results: Of the 1,455 patients in the cohort who survived to S2P, 5.2% died and 2.3% were referred for transplant. Overall event rates at 30 and 100 days after S2P were 2% and 5%, respectively. Independent risk factors for mortality and transplantation referral included the presence of a known genetic syndrome, shunt type at stage 1 procedure (S1P), tricuspid valve repair at S1P, longer time to extubation and reintubation after S1P, ≥ moderate tricuspid regurgitation prior to S2P, younger age at S2P, and the risk groups identified in the classification and regression tree analysis (extracorporeal membrane oxygenation after S1P and longer S2P cardiopulmonary bypass time without extracorporeal membrane oxygenation). Conclusions: Mortality and transplantation referral rates after S2P to 1 year of age remain high ∼7%. Many of the identified risk factors after S2P are similar to those established for interstage factors around the S1P, whereas others may be unique to the period after S2P.

Addressing Disparities in Pediatric Congenital Heart Disease: A Call for Equitable Health Care.

While significant progress has been made in reducing disparities within the US health care system, notable gaps remain. This article explores existing disparities within pediatric congenital heart disease care. Congenital heart disease, the most common birth defect and a leading cause of infant death, has garnered substantial attention, revealing certain disparities within the US health care system. Factors such as race, ethnicity, insurance coverage, socioeconomic status, and geographic location are all commonalities that significantly affect health disparities in pediatric congenital heart disease. This comprehensive review sheds light on disparities from diverse perspectives in pediatric care, demonstrates the inequities and inequalities leading to these disparities, presents effective solutions, and issues a call to action for providers, institutions, and the health care system. Recognizing and addressing these disparities is imperative for ensuring equitable care and enhancing the long-term well-being of children affected by congenital heart disease. Implementing robust, evidence-based frameworks that promote responsible and safe interventions is fundamental to enduring change.

Mind the Gap! Working Toward Gender Equity in Pediatric and Congenital Heart Disease: Present and Future.

Evidence from medicine and other fields has shown that gender diversity results in better decision making and outcomes. The incoming workforce of congenital heart specialists (especially in pediatric cardiology) appears to be more gender balanced, but past studies have shown many inequities. Gender-associated differences in leadership positions, opportunities presented for academic advancement, and recognition for academic contributions to the field persist. In addition, compensation packages remain disparate if evaluated based on gender with equivalent experience and expertise. This review explores these inequities and has suggested individual and institutional changes that could be made to recruit and retain women, monitor the climate of the institution, and identify and eliminate bias in areas like salary and promotions.

Perinatal Stressors and Consequences for Neonates with Critical Congenital Heart Disease.

INTRODUCTION: The prenatal diagnosis of congenital heart disease (CHD) is a traumatic event that can cause expectant parents to experience anxiety, depression, and toxic stress. Prenatal exposure to stress may impact neonatal postoperative outcomes. In addition, expectant parents may have other psychosocial stressors that may compound maternal stress. We investigated the relationship between stress in pregnancies complicated by prenatally diagnosed CHD and their neonatal outcomes. METHODS: A pilot retrospective cohort study of pregnancies with prenatally diagnosed critical CHD (2019-2021) was performed. The collected data included pregnancy characteristics and neonatal and postoperative outcomes (including the need for exogenous corticosteroid treatment (ECT)). In order to quantify prenatal stressors, a composite prenatal stress score (PSS) was established and utilized. RESULTS: In total, 41 maternal-fetal dyads were evaluated. Thirteen (32%) neonates had single-ventricle anatomy. The need for ECT after CHD surgery was associated with higher pregnant patient PSS (p = 0.01). PSS did not correlate with birthweight, infection, or hypoglycemia in the neonatal period. CONCLUSIONS: Prenatal stress is multifactorial; higher PSS is correlates with post-bypass ECT, suggesting that a stressful intrauterine environment may be associated with worse neonatal postoperative outcomes.
