Emerging 3D technologies and applications within congenital heart disease: teach, predict, plan and guide.

3D visualization technologies have evolved to become a mainstay in the management of congenital heart disease (CHD) with a growing presence within multiple facets. Printed and virtual 3D models allow for a more comprehensive approach to educating trainees and care team members. Computational fluid dynamics can take 3D modeling to the next level, by predicting post-procedural outcomes and helping to determine surgical approach.

Association between time of day and CPR quality as measured by CPR hemodynamics during pediatric in-hospital CPR.

Introduction: Patients who suffer in-hospital cardiac arrest (IHCA) are less likely to survive if the arrest occurs during nighttime versus daytime. Diastolic blood pressure (DBP) as a measure of chest compression quality was associated with survival from pediatric IHCA. We hypothesized that DBP during CPR for IHCA is lower during nighttime versus daytime.

Multicenter Analysis of Truncal Valve Management and Outcomes in Children with Truncus Arteriosus.

Truncal valve management in patients with truncus arteriosus is a clinical challenge, and indications for truncal valve intervention have not been defined. We sought to evaluate truncal valve dysfunction and primary valve intervention in patients with truncus arteriosus and determine risk factors for later truncal valve intervention. We conducted a retrospective cohort study of children who underwent truncus arteriosus repair at 15 centers between 2009 and 2016.

Registry-based trials: a potential model for cost savings?

Background/aims: Registry-based trials have emerged as a potentially cost-saving study methodology. Early estimates of cost savings, however, conflated the benefits associated with registry utilisation and those associated with other aspects of pragmatic trial designs, which might not all be as broadly applicable. In this study, we sought to build a practical tool that investigators could use across disciplines to estimate the ranges of potential cost differences associated with implementing registry-based trials versus standard clinical trials.

Predicting and Surviving Prolonged Critical Illness After Congenital Heart Surgery.

Objectives: Prolonged critical illness after congenital heart surgery disproportionately harms patients and the healthcare system, yet much remains unknown. We aimed to define prolonged critical illness, delineate between nonmodifiable and potentially preventable predictors of prolonged critical illness and prolonged critical illness mortality, and understand the interhospital variation in prolonged critical illness.

Design: Observational analysis.

Medico-legal implications of the fetal inflammatory response syndrome.

Babies who sustain long term neurologic injury and disability are frequent subjects in medical malpractice litigation. In the United States, the tort system enables adjudication of claims through a proscribed system. This paper will review salient elements of the tort system-duty, breach, causation, and damages- and how they apply to encephalopathic infants whose injuries are believed to be the result of fetal inflammatory response syndrome (FIRS) and/or hypoxic-ischemic damage.

Paved With Good Intentions: Hospital Visitation Restrictions in the Age of Coronavirus Disease 2019.

Hospital visitation restrictions have been widely implemented during the coronavirus disease 2019 pandemic as a means of decreasing the transmission of coronavirus. While decreasing transmission is an important goal, it is not the only goal that quality healthcare must aim to achieve. Severely restricted visitation policies undermine our ability to provide humane, family-centered care, particularly during critical illness and at the end of life.

Prospective Evaluation of Radiation Dose Escalation in Patients With High-Risk Neuroblastoma and Gross Residual Disease After Surgery: A Report From the Children's Oncology Group ANBL0532 Study.

Purpose: A primary objective of the Children's Oncology Group (COG) ANBL0532 phase III study was to assess the effect of increasing local dose of radiation to a residual primary tumor on the cumulative incidence of local progression (CILP) in patients with high-risk neuroblastoma.

Patients And Methods: Newly diagnosed patients with high-risk neuroblastoma were randomly assigned or assigned to receive single or tandem autologous stem-cell transplantation (SCT) after induction chemotherapy. Local control consisted of surgical resection during induction chemotherapy and radiotherapy after last SCT.

T-piece resuscitator or self-inflating bag during neonatal resuscitation: a scoping review.

Background: To identify the evidence for administering positive pressure ventilation (PPV) to infants at birth by either T-piece resuscitator (TPR) or self-inflating bag (SIB), and to determine whether a full systematic review (SR) is warranted.

Methods: Guided by the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for scoping reviews, eligible studies included peer-reviewed human studies, prospectively or retrospectively comparing a TPR vs. SIB for administering PPV at birth.

Normoxic re-oxygenation ameliorates end-organ injury after cardiopulmonary bypass.

Background: In a rabbit model of cardiopulmonary bypass (CPB) and cardioplegic arrest, we previously showed that hyperoxic myocardial reperfusion was associated with increased left ventricular (LV) systolic dysfunction and myocardial injury compared with normoxic reperfusion. The aim of this study was to evaluate in our experimental model the impact of post-CPB reperfusion conditions on other organs potentially vulnerable to ischemic injury such as the brain and kidney.

Methods: After 60 min of CPB, aortic cross-clamp, and cold cardioplegic arrest, rabbits were reperfused under hyperoxic or normoxic conditions for 120 min.

Elevated Serum Titanium Levels in Children With Early Onset Scoliosis Treated With Growth-friendly Instrumentation.

Background: A previous study showed significantly higher serum titanium levels in patients with early-onset scoliosis (EOS) treated with traditional growing rods (TGR) and magnetically controlled growing rods (MCGR) compared with controls. Children with vertical expandable prosthetic titanium rib (VEPTR) were not assessed. The purpose of this study was to compare serum titanium levels in EOS patients treated with TGR, MCGR, and VEPTR.

Defining the volume of consultations for musculoskeletal infection encountered by pediatric orthopaedic services in the United States.

Objective: Adequate resources are required to rapidly diagnose and treat pediatric musculoskeletal infection (MSKI). The workload MSKI consults contribute to pediatric orthopaedic services is unknown as prior epidemiologic studies are variable and negative work-ups are not included in national discharge databases. The hypothesis was tested that MSKI consults constitute a substantial volume of total consultations for pediatric orthopaedic services across the United States.

Ethical decision-making for children with neuromuscular disorders in the COVID-19 crisis.

The sudden appearance and proliferation of coronavirus disease 2019 has forced societies and governmental authorities across the world to confront the possibility of resource constraints when critical care facilities are overwhelmed by the sheer numbers of grievously ill patients. As governments and health care systems develop and update policies and guidelines regarding the allocation of resources, patients and families affected by chronic disabilities, including many neuromuscular disorders that affect children and young adults, have become alarmed at the possibility that they may be determined to have less favorable prognoses due to their underlying diagnoses and thus be assigned to lower priority groups. It is important for health care workers, policymakers, and government officials to be aware that the long-term prognoses for children and young adults with neuromuscular disorders are often more promising than previously believed due to a better understanding of the natural history of these diseases, benefits of multidisciplinary supportive care, and novel molecular therapies that can dramatically improve the disease course.

Central Venous Catheter Utilization and Complications in the Pediatric Cardiac ICU: A Report From the Pediatric Cardiac Critical Care Consortium (PC4).

Objectives: Current central venous catheter utilization in patients within pediatric cardiac ICUs is not well elucidated. We aim to describe current use of central venous catheters in a multi-institutional cohort and to explore the prevalence and risk factors for central line-associated thrombosis and central line-associated bloodstream infections.

Design: Observational analysis.

Laboratory misdiagnosis of von Willebrand disease in post-menarchal females: A multi-center study.

Increased awareness of von Willebrand Disease (VWD) has led to more frequent diagnostic laboratory testing, which insurers often dictate be performed at a facility with off-site laboratory processing, instead of a coagulation facility with onsite processing. Off-site processing is more prone to preanalytical variables causing falsely low levels of von Willebrand Factor (VWF) due to the additional transport required. Our aim was to determine the percentage of discordance between off-site and onsite specimen processing for VWD in this multicenter, retrospective study.

A Validated Model for Sudden Cardiac Death Risk Prediction in Pediatric Hypertrophic Cardiomyopathy.

Background: Hypertrophic cardiomyopathy is the leading cause of sudden cardiac death (SCD) in children and young adults. Our objective was to develop and validate a SCD risk prediction model in pediatric hypertrophic cardiomyopathy to guide SCD prevention strategies.

Methods: In an international multicenter observational cohort study, phenotype-positive patients with isolated hypertrophic cardiomyopathy <18 years of age at diagnosis were eligible.

Improved National Outcomes Achieved in a Cardiac Learning Health Collaborative Based on Early Performance Level.

Objective: Within the National Pediatric Cardiology Quality Improvement Collaborative (NPC-QIC), a learning health network developed to improve outcomes for patients with hypoplastic left heart syndrome and variants, we assessed which centers contributed to reductions in mortality and growth failure.

Study Design: Centers within the NPC-QIC were divided into tertiles based on early performance for mortality and separately for growth failure. These groups were evaluated for improvement from the early to late time period and compared with the other groups in the late time period.

Impact of standardized prenatal documentation among newborns with ductal-dependent heart disease.

Introduction: Absent risk stratification, variable physiology of ductal-dependent congenital heart disease (DD-CHD) imparts risk of over-medicalization and unnecessary exclusion from early parental bonding.

Methods: Single-center retrospective cohort study of term infants with isolated prenatally diagnosed DD-CHD expected to require immediate advanced resuscitation/intervention (2005-2017). Standardized documentation (2015 onward) included diagnosis, expected saturations, and allowability of postnatal parental bonding.

Minimally invasive surgery for pediatric renal tumors: A systematic review by the APSA Cancer Committee.

Unlabelled: Minimally invasive nephrectomy is performed routinely for adult renal tumors and for many benign pediatric conditions. Although open radical nephroureterectomy remains the standard of care for Wilms tumor and most pediatric renal malignancies, there are an increasing number of reports of minimally invasive surgery (MIS) for those operations as well. The APSA Cancer Committee performed a systematic review to better understand the risks and benefits of MIS in pediatric patients with renal tumors.

Angiotensin-Converting Enzyme Inhibitor Prescription for Patients With Single Ventricle Physiology Enrolled in the NPC-QIC Registry.

Background The routine use of angiotensin-converting enzyme inhibitors (ACEI) during palliation of hypoplastic left heart syndrome is controversial. We sought to describe ACEI prescription in the interstage between stage 1 palliation (stage I Norwood procedure) discharge and stage 2 palliation (stage II superior cavopulmonary anastomosis procedure) admission using the NPC-QIC (National Pediatric Cardiology Quality Improvement Collaborative) registry. Methods and Results Analysis of all patients (n=2180) enrolled in NPC-QIC from 2008 to 2016 included preoperative anatomy, risk factors, and echocardiographic data.

Cardiac MRI for Patients With Cardiac Implantable Electronic Devices.

Patients with cardiac implantable electronic devices (CIEDs) require cardiac MRI (CMRI) for a variety of reasons. The purpose of this study is to review and evaluate the value and safety of CMRI for patients with in situ CIEDs. Late gadolinium enhancement CMRI is the reference standard for assessing myocardial viability in patients with ventricular tachycardia before ablation of arrhythmogenic substrates.
