Neonatal Depression Is Associated With 1-Year Mortality in Critical Congenital Heart Disease.

Background Low 5-minute Apgar scores (AS) are predictive of term and preterm neonatal mortality but have not been well studied in the critical congenital heart disease (CCHD) population. We analyzed US national vital statistics data to evaluate the association between neonatal depression (AS 0-3) and 1-year mortality in CCHD. Methods and Results We performed a retrospective cohort study using 2014 to 2018 Centers for Disease Control and Prevention cohort-linked birth certificate and infant death records.

Aortic root rotational position associates with aortic valvar incompetence and aortic dilation after arterial switch operation for transposition of the great arteries.

Purpose: Aortic dilation and valvar regurgitation can develop in transposition of the great arteries (TGA) after the arterial switch operation (ASO). Variation in aortic root rotational position affects flow dynamics in patients without congenital heart disease. The aim of this study was to assess neo-aortic root (neo-AoR) rotational position and its association with neo-AoR dilation, ascending aorta (AAo) dilation, and neo-aortic valvar regurgitation in TGA following ASO.

Altered white matter connectivity in children with congenital heart disease with single ventricle physiology.

Children born with congenital heart disease (CHD) have seen a dramatic decrease in mortality thanks to surgical innovations. However, there are numerous risk factors associated with CHD that can disrupt neurodevelopment. Recent studies have found that psychological deficits and structural brain abnormalities persist into adulthood.

Severe Maternal Morbidity in Pregnancies Complicated by Fetal Congenital Heart Disease.

Background: Maternal risk factors for fetal congenital heart disease (CHD) may also be associated with delivery complications in the mother.

Objectives: This study aimed to determine the prevalence of and risk factors for severe maternal morbidity (SMM) and maternal hospital transfer in pregnancies complicated by fetal CHD.

Methods: A population-based retrospective cohort study utilizing linked Ohio birth certificates and birth defect data for all live births from 2011 to 2015 was performed.

Patent Ductus Arteriosus Stent Versus Surgical Aortopulmonary Shunt for Initial Palliation of Cyanotic Congenital Heart Disease with Ductal-Dependent Pulmonary Blood Flow: A Systematic Review and Meta-Analysis.

Background In patients with ductal-dependent pulmonary blood flow, initial palliation includes catheter-based patent ductus arteriosus (PDA) stent or surgical aortopulmonary shunt (APS). This meta-analysis aimed to compare outcomes between PDA stent and APS. Methods and Results A comprehensive literature search yielded six retrospective observational studies.

Myocardial Parametric Mapping by Cardiac Magnetic Resonance Imaging in Pediatric Cardiology and Congenital Heart Disease.

Parametric mapping, that is, a pixel-wise map of magnetic relaxation parameters, expands the diagnostic potential of cardiac magnetic resonance by enabling quantification of myocardial tissue-specific magnetic relaxation on an absolute scale. Parametric mapping includes T mapping (native and postcontrast), T and T* mapping, and extracellular volume measurements. The myocardial composition is altered in various disease states affecting its inherent magnetic properties and thus the myocardial relaxation times that can be directly quantified using parametric mapping.

Altered erythropoiesis in newborns with congenital heart disease.

Background: Fetal hypoxia has been implicated in fetal growth restriction in congenital heart disease (CHD) and leads to stress erythropoiesis in utero. The objective is to assess erythropoiesis and its association with growth in newborns with CHD.

Methods: Fetuses with prenatally diagnosed CHD from 2013 to 2018 were retrospectively reviewed.

Pattern of head circumference growth following bidirectional Glenn in infants with single ventricle heart disease.

Background: Infants with single ventricle congenital heart disease demonstrate increasing head growth after bidirectional Glenn; however, the expected growth trajectory has not been well described.

Aims: 1) We will describe the pattern of head circumference growth in the first year after bidirectional Glenn. 2) We will determine if head growth correlates with motor developmental outcomes approximately 12 months after bidirectional Glenn.

Atrioventricular Valve Regurgitation in Single Ventricle Heart Disease: A Common Problem Associated With Progressive Deterioration and Mortality.

The Fontan procedure has provided patients with single ventricle physiology extended survival into adulthood and in many cases has improved their quality of life. Atrioventricular valve regurgitation (AVVR) is common in single ventricle patients and is associated with increased risk of mortality. AVVR is more common in patients with a systemic tricuspid or common atrioventricular valve but is generally progressive irrespective of underlying valve morphology.

Risk Factors for Mortality and Ventricular Tachycardia in Patients With Repaired Tetralogy of Fallot: A Systematic Review and Meta-analysis.

Background: Patients with repaired tetralogy of Fallot (rTOF) have increased risk for mortality, sudden cardiac death, and ventricular tachycardia (VT). The aim of this systematic review and meta-analysis is to offer an updated analysis of risk factors following significant changes in surgical and perioperative management.

Methods: A meta-analysis based on the published literature between 2008 and 2018 was conducted.

Tricuspid atresia with restrictive foramen ovale: A rare combination with implications on fetal growth.

Restrictive atrial communication is rarely reported in tricuspid atresia but when present it can lead to important morbidity. We describe two fetuses with tricuspid atresia with restrictive foramen ovale who were found to have fetal growth failure. Fetal echocardiography detected a restrictive atrial communication by flow acceleration on color Doppler and significant right atrial dilation in one patient; the atrial septum was not well interrogated in the other patient.

Merkel cell polyomavirus in cutaneous squamous cell carcinoma of immunocompetent individuals.

Squamous cell carcinoma (SCC) is the second most frequently diagnosed skin cancer. It has a higher incidence in immunosuppressed individuals such as organ transplant recipients and human immunodeficiency virus (HIV) carriers. Recently, a newly described polyoma virus, Merkel cell polyomavirus (MCPyV), was found in Merkel cell carcinoma (MCC), a rare aggressive skin cancer also associated with immunosuppression.

Methylation not a frequent "second hit" in tumors with germline BRCA mutations.

Mutations in tumor suppressor genes BRCA1 and BRCA2 confer an increased lifetime risk of breast and ovarian cancer. Loss of heterozygosity (LOH) of the wildtype allele has been observed in approximately 80% of tumors from BRCA1 carriers and 70% of tumors from BRCA2 carriers and accounts for the majority of the "second-hits" occurring in BRCA-related tumors. Few sporadic tumors have been reported to have mutations in BRCA.
