Pediatric sudden cardiac arrest

Sayed Nour, Daniel Carbognani, Juan Carlos Chachques
Sudden cardiac arrest (SCA) remains a major problem for health authorities worldwide. Insufficiencies of current cardiopulmonary resuscitation (CPR) are most probably related to an inappropriate concept and applied methods that still concentrate on heartbeat as priority, instead of blood circulation to maintain organs' perfusions. The aim of this works is to propose a new therapeutic approach for SCA in a more effective and secure manner compared with current CPR methods. It correlates to a non-invasive circulatory flow restoration (CFR) device composed of a multilayered thoracic and infradiaphragmatic compartments that will be pulsated alternatively and in fixed frequencies using a low-pressure pneumatic generator...

General Practitioners frequently see children with medical conditions that may evolve into an emergency if not promptly attended to. The most common emergencies encountered in pediatric office practice are respiratory distress, dehydration, anaphylaxis, seizures and trauma. Assessment of children is sometimes difficult as the signs and symptoms might be subtle and not markedly expressed. Also, normal value of vital signs vary with age, thus their interpretation requires discrete knowledge of age appropriate values...

Predictive genetic testing in minors should be considered when clinical intervention is available. Children who carry a pathogenic variant for an inherited arrhythmia or cardiomyopathy require regular cardiac screening and may be prescribed medication and/or be told to modify their physical activity. Medical genetics and pediatric cardiology charts were reviewed to identify factors associated with uptake of genetic testing and cardiac evaluation for children at risk for long QT syndrome, hypertrophic cardiomyopathy or arrhythmogenic right ventricular cardiomyopathy...

The clinical presentation of acute myocarditis in children may range from asymptomatic to sudden cardiac arrest. This study analyzed the clinical spectrum of acute myocarditis in children to identify factors that could aid primary care physicians to predict the need for extracorporeal membrane oxygenation (ECMO) earlier and consult the pediatric cardiologist promptly. Between October 2011 and September 2016, we retrospectively analyzed 60 patients aged 18 years or younger who were admitted to our pediatric emergency department with a definite diagnosis of acute myocarditis...

Catecholaminergic polymorphic ventricular tachycardia is a rare cause of exercise-induced arrhythmia and sudden cardiac death in the pediatric patient. This arrhythmia is difficult to diagnose in the emergency department, given the range of presentations; thus, a familiarity with and high index of suspicion for this pathology are crucial. Furthermore, recognition of the characteristic electrocardiogram findings and knowledge of the management of the symptomatic patient are necessary, given the risk of arrhythmia recurrence and cardiac arrest...

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a life threatening hematological disorder associated with severe systemic inflammation caused by an uncontrolled and ineffective immune response resulting in cytokine storm. Epstein-Barr virus (EBV) is the most common infectious agent in patients with the viral-associated HLH. Limited numbers of cases with cardiac complication have been demonstrated in other viral-associated HLH patients. Herein, we report a pediatric case of severe EBV-associated HLH with cardiac complications...

Sudden cardiac arrest (SCA) in the pediatric population is a rare and potentially devastating occurrence. An understanding of the differential diagnosis for the etiology of the cardiac arrest allows for the most effective emergency care and provides the patient with the best possible outcome. Pediatric SCA can occur with or without prodromal symptoms and may occur during exercise or rest. The most common cause is arrhythmia secondary to an underlying channelopathy, cardiomyopathy, or myocarditis. After stabilization, evaluation should include electrocardiogram, chest radiograph, and echocardiogram...

BACKGROUND: Arrhythmogenic right ventricular cardiomyopathy (ARVC) is a complex and clinically heterogeneous arrhythmic condition. Incomplete penetrance and variable expressivity are particularly evident in ARVC, making clinical decision-making challenging. METHODS: Pediatric and adult cardiologists, geneticists, genetic counsellors, ethicists, nurses, and qualitative researchers are collaborating to create the Canadian ARVC registry using a web-based clinical database...

FH is an autosomal dominant genetic disorder characterized by increased TC and LDL level, which leads to xanthomas, atherosclerosis, and cardiac complications even in childhood. The treatment options are diet, medical treatment, lipid apheresis, and LT. The aim of our study was to analyze our data of patients with FH. Between 2004 and 2015, there were 51 patients who underwent pediatric LT at our center. All patients with FH were identified, and the data were retrospectively analyzed. There were eight patients with homozygous FH in the median age of 10 years (IQR 6-12) who underwent LT...

OBJECTIVE: Although sudden cardiac death is rare in children, an intracardiac defibrillator system is indicated in children with various types of cardiomyopathy, primary electrical diseases, and after surgical repair of congenital heart defects. The use of transvenous defibrillator lead systems is limited in pediatric patients because of a small body size and/or limited vascular access. Subcutaneous array leads combined with an abdominally placed generator can enable implantation. METHOD: This is a retrospective study of 13 patients who underwent subcutaneous defibrillator implantation between September 2010 and March 2015...

Sudden cardiac arrest (SCA) or sudden cardiac death (SCD) in children and adolescents is a devastating event. Although the true incidence is unclear, the etiologies are not. Strategies for prevention include both primary as well as secondary prevention strategies, and these strategies are not mutually exclusive. From a primary prevention standpoint, many of the episodes of SCA or SCD may occur without any antecedent warning signs and in the absence of an important family history. There are a subset of children and adolescents who may have antecedent warning signs and symptoms such as syncope with exercise, chest pain, and palpitations...

Palpitations are a common complaint, particularly in teenagers, with etiologies ranging from no detectable cardiac dysrhythmia to life-threatening dysrhythmias. Despite the fact that as many as 50% of children and adolescents may be asymptomatic prior to experiencing sudden cardiac arrest, the occurrence of palpitations may afford the opportunity to detect a potentially lethal arrhythmia condition. This article discusses the evaluation of palpitations in the pediatric population by focusing on the two most common life-threatening arrhythmia diagnoses that may initially manifest itself in the pediatric population with the chief complaint of palpitations-Wolff-Parkinson-White syndrome and the long QT syndrome...

BACKGROUND: Conditions associated with sudden cardiac arrest/death (SCA/D) in youth often have a genetic etiology. While SCA/D is uncommon, a pro-active family screening approach may identify these inherited structural and electrical abnormalities prior to symptomatic events and allow appropriate surveillance and treatment. This study investigated the diagnostic utility of exome sequencing (ES) by evaluating the capture and coverage of genes related to SCA/D. METHODS: Samples from 102 individuals (13 with known molecular etiologies for SCA/D, 30 individuals without known molecular etiologies for SCA/D and 59 with other conditions) were analyzed following exome capture and sequencing at an average read depth of 100X...

BACKGROUND: Long-QT syndrome (LQTS) may result in syncope, seizures, or sudden cardiac arrest. Although 16 LQTS-susceptibility genes have been discovered, 20% to 25% of LQTS remains genetically elusive. METHODS AND RESULTS: We performed whole-exome sequencing child-parent trio analysis followed by recessive and sporadic inheritance modeling and disease-network candidate analysis gene ranking to identify a novel underlying genetic mechanism for LQTS. Subsequent mutational analysis of the candidate gene was performed with polymerase chain reaction, denaturing high-performance liquid chromatography, and DNA sequencing on a cohort of 33 additional unrelated patients with genetically elusive LQTS...

OBJECTIVE: Hyperkalemia is one of the reversible causes of cardiac arrest in children. The Advanced Cardiovascular Life Support guidelines have specific recommendations on the choice and sequence of medications for treatment of life-threatening hyperkalemia. However, the Pediatric Advanced Life Support guidelines have no specific treatment recommendations. The objective of this study was to measure the extent to which opinions diverge among pediatricians on the choice and sequence of medication administration in the management of hyperkalemia during cardiac arrest...
