The role of hemodynamics in cardiovascular development is not well understood. Indeed, it would be remarkable if it were, given the dauntingly complex array of intricately synchronized genetic, molecular, mechanical, and environmental factors at play. However, with congenital heart defects affecting around 1 in 100 human births, and numerous studies pointing to hemodynamics as a factor in cardiovascular morphogenesis, this is not an area in which we can afford to remain in the dark. This review seeks to present the case for the importance of research into the biomechanics of the developing cardiovascular system...

Congenital heart defects (CHD) are structural malformations found at birth with a prevalence of 1%. The clinical trajectory of CHD is highly variable and thus in need of robust diagnostics and therapeutics. Major surgical interventions are often required for most CHDs. In Africa, despite advances in life sciences infrastructure and improving education of medical scholars, the limited clinical data suggest that CHD detection and correction are still not at par with the rest of the world. But the toll and genetics of CHDs in Africa has seldom been systematically investigated...

BACKGROUND: Down syndrome (DS) is the most common autosomal chromosomal anomaly in liveborn infants. About 40% of infants with DS have a major congenital heart defect (CHD). Among them, atrioventricular septal defects (AVSD), atrial septal defects (ASD), ventricular septal defect (VSD) and Tetralogy of Fallot (ToF) are the most common. The aim of this study was to estimate the sex difference in the occurrence of CHD in infants with DS comparing it with non-DS infants. METHOD: Live birth cases of DS diagnosed by the first year of life were extracted from the Registry of Congenital Anomalies of Tuscany (2003-2015 period)...

BACKGROUND: Congenital heart disease (CHD) is the most common class of birth defects, which encompasses a broad spectrum of severity ranging from relatively minor to extremely complex. Improvements in surgery and intensive care have resulted in an increasing number of infants with the most complex lesions surviving after surgery until the time of discharge from the hospital, but there remain concerns about out-of-hospital mortality, variability in how services are provided at the time of discharge and beyond, and difficulties experienced by some families in accessing care...

BACKGROUND: Prenatal diagnosis ameliorates some preoperative and postoperative outcomes in critical congenital heart disease (CHD). Despite large variability among anatomical defect types, nearly half of them are diagnosed antenatally. We aimed to investigate the effect of the antenatal diagnosis on prereferral mortality of infants with critical CHD in a center without cardiovascular surgery clinic. METHODS: Medical records of the neonates who were diagnosed with critical CHD between the years 2010 and 2016 in Zekai Tahir Burak Women's health Education and Research Hospital were retrospectively reviewed for the study...

BACKGROUND AND PURPOSE: It is well-established that a high prevalence of infants with congenital heart defects surviving to childhood have neurodevelopmental abnormalities. The etiology is not clear. In this study, we aimed to find prenatal neuroanatomic changes in fetuses with congenital heart disease to better understand the pathophysiology behind these sequelae. MATERIALS AND METHODS: A retrospective study of 46 fetal brain MR imaging scans was performed at a tertiary medical center during a 4-year period...

BACKGROUND: Electrical dyssynchrony and prolonged QRS duration are common in patients with repaired tetralogy of Fallot (ToF). It has been linked to increased risk of sudden cardiac death and right ventricular (RV) dysfunction. We investigated myocardial dyssynchrony using cardiac magnetic resonance imaging (CMR) and feature tracking analysis (FT) in this setting and compared it to myocardial deformation, conventional parameters of ventricular dysfunction and clinical parameters. METHODS AND RESULTS: Patients underwent standardized CMR investigations as part of a nationwide study...

Primary adrenal insufficiency (PAI) is characterized by impaired production of steroid hormones due to an adrenal cortex defect. This condition incurs a risk of acute insufficiency which may be life-threatening. Today, 80% of pediatric forms of PAI have a genetic origin but 5% have no clear genetic support. Recently discovered mutations in genes relating to oxidative stress have opened the way to research on genes unrelated to the adrenal gland. Identification of causal mutations in a gene responsible for PAI allows genetic counseling, guidance of follow-up and prevention of complications...

BACKGROUND: As survival rates for infants born with severe forms of cardiac defects (congenital heart defect [CHD]) improve, attention is directed to evaluating factors that affect the child's short- and long-term outcomes including parental quality of life (QOL). PURPOSE: The purpose of this review was to identify how parental QOL is affected when having a child with a CHD. Factors that influence parental QOL when having a child with a CHD will also be described...

Right ventricle (RV) remodelling occurs in neonatal patients born with ventricular septal defect (VSD). The presence of a defect between the two ventricles allows for shunting of blood from the left to right side. The resulting RV hypertrophy leads to molecular remodelling which has thus far been largely investigated using right atrial (RA) tissue. In this study we used proteomic and phosphoproteomic analysis in order to determine any difference between the proteomes for RA and RV. Samples were therefore taken from the RA and RV of five infants (0...

A review is presented of data published in medical literature related to the screening used for the early detection of complex congenital heart disease in apparently healthy newborns in several cities of the world, including those reported in Mexico. The screening was performed due to the knowledge of the pathophysiology of indirect hypoxia data, observation of differential cyanosis and the consequent difference in the values of pre- and post-ductal pulse oximetry derived from the ductal and/or atrial septal defect dependence of several severe congenital heart diseases...

BACKGROUND: Health outcomes are improved when newborn babies with critical congenital heart defects (CCHDs) are detected before acute cardiovascular collapse. The main screening tests used to identify these babies include prenatal ultrasonography and postnatal clinical examination; however, even though both of these methods are available, a significant proportion of babies are still missed. Routine pulse oximetry has been reported as an additional screening test that can potentially improve detection of CCHD...

Previous research suggested an association between maternal exposure to ambient air pollutants and risk of congenital heart defects (CHDs), though the effects of particulate matter ≤10μm in aerodynamic diameter (PM10 ) on CHDs are inconsistent. We used two machine learning models (i.e., random forest (RF) and gradient boosting (GB)) to investigate the non-linear effects of PM10 exposure during the critical time window, weeks 3-8 in pregnancy, on risk of CHDs. From 2009 through 2012, we carried out a population-based birth cohort study on 39,053 live-born infants in Beijing...

Left ventricular noncompaction cardiomyopathy (LVNC) is characterized by compact and trabecular layers of the left ventricular myocardium. This cardiomyopathy may occur with congenital heart disease (CHD). Single cases document co-occurrence of LVNC and heterotaxy, but no data exist regarding the prevalence of this association. This study sought to determine whether a non-random association of LVNC and heterotaxy exists by evaluating the prevalence of LVNC in patients with heterotaxy. In a retrospective review of the Indiana Network for Patient Care, we identified 172 patients with heterotaxy (69 male, 103 female)...

Zic family proteins have been investigated in various biomedical studies. Here we summarize the contact points between Zic proteins and recent medical research. The topics cover a wide range, reflecting the pleiotropic roles of these proteins in early embryogenesis and organogenesis. Zic1, Zic2, and Zic3 proteins play important roles in the development of axial and limb bones, and of muscles, among the derivatives of the notochord and somites. Zic1 is involved in bone's response to mechanical stress, and it also serves as a marker specific for brown adipocytes...

Practice variation is a potentially important measure of healthcare quality. The IMPACT registry provides a representative national sample with which to study practice variation in trans-catheter interventions for congenital heart disease. METHODS: We studied cases for closure of atrial septal defect (ASD) and patent ductus arteriosus (PDA) in IMPACT between January 1, 2011, and September 30, 2015, using hierarchical multivariate models studying (1) the distribution of indications for closure and (2) in patients whose indication for closure was left (LVVO) or right ventricular volume overload (RVVO), the factors influencing probability of closure of a small defect (either in size or in terms of the magnitude of shunt)...

Genomics designates the coordinated investigation of a large number of genes in the context of a biological process or disease. It may be long before we attain comprehensive understanding of the genomics of common complex cardiovascular diseases (CVDs) such as inherited cardiomyopathies, valvular diseases, primary arrhythmogenic conditions, congenital heart syndromes, hypercholesterolemia and atherosclerotic heart disease, hypertensive syndromes, and heart failure with preserved/reduced ejection fraction. Nonetheless, as genomics is evolving rapidly, it is constructive to survey now pertinent concepts and breakthroughs...
