Abstract
In 1900, Fiedler first reported autopsy cases with peculiar inflammation of the myocardium, which he named interstitial myocarditis. He postulated an isolated cardiac inflammation of the myocardium in the absence of multiorgan involvement and with a poor prognosis due to invisible microorganisms, which years later would have been identified as viruses. The revision of original histologic sections by Schmorl showed cases with lymphocytes and others with giant-cell inflammatory histotypes. The in vivo diagnosis of myocarditis became possible thanks to right cardiac catheterization with endomyocardial biopsy (EMB). The gold standard for diagnosis was achieved with the employment of immunohistochemistry and molecular investigation by Polymerase Chain Reaction (PCR), which allows for the detection of viruses as causal agents. Both RNA and DNA were revealed to be cardiotropic, with a common receptor (CAR). A protease, coded by coxsackie virus, disrupts the cytoskeleton and accounts for cell death. Unfortunately, vaccination, despite having been revealed to be effective in animal experiments, has not yet entered the clinical field for prevention. Cardiac Magnetic Resonance turned out to be a revolutionary tool for in vivo diagnosis through the detection of edema (inflammatory exudate). Myocarditis may be fulminant in terms of clinical presentation but not necessarily fatal. The application of ExtraCorporeal Membrane Oxygenation (ECMO) allows for relieving the overloaded native heart.

Abstract
Despite extracorporeal membrane oxygenation (ECMO) utilization in nearly 20% of cases, there are limited data in children with acute fulminant myocarditis (AFM) requiring ECMO. Herein we identify risk factors for death or heart transplant (HT) in children with AFM supported with ECMO, describe our experience with left atrial (LA) decompression, and depict long-term outcomes of survivors. We performed a retrospective cohort of patients <18 years with AFM (≤14 days of symptoms, rapid cardiogenic shock, and normal left ventricular [LV] size on presentation) supported with ECMO admitted to a single intensive care unit from 1997 to 2021. Among 28 patients (median age 9 years), 21 (75%) survived to discharge without HT. Patients were supported on ECMO for a median of 6 days. Three patients were bridged to HT with durable ventricular assist devices (VAD). Four patients died, two of whom were supported with VAD. At presentation, seven (25%) patients had high grade or complete atrioventricular block and eight (29%) had ventricular tachycardia. Before ECMO cannulation, 21 (75%) patients received CPR. The death/HT group had higher peak troponin levels (12.5 vs . 1.0 ng/ml, p = 0.02) and initial mean LA or pulmonary capillary wedge pressure (27 vs . 18 mm Hg, p = 0.03). Left atrial decompression was performed in 22 patients (79%). Twenty-two (79%) had acute myocarditis on endomyocardial biopsy. Among transplant-free survivors, 18 (86%) had normalization in LV function (median 7 days); the remaining three patients had persistent mild LV dysfunction at last follow-up (median 842 days). Transplant-free survival of pediatric patients with AFM supported on ECMO was 75% and associated with lower initial LA pressure and lower peak troponin. Recovery in ventricular function among survivors was rapid and durable.

Short-Term Mortality Among Pediatric Patients With Heart Diseases Undergoing Veno-Arterial Extracorporeal Membrane Oxygenation: A Systematic Review and Meta-Analysis. J Am Heart Assoc 2023; 12:e029571. [PMID: 38063152 PMCID: PMC10863771 DOI: 10.1161/jaha.123.029571] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/21/2023] [Accepted: 11/08/2023] [Indexed: 12/20/2023]
Abstract
BACKGROUND Veno-arterial extracorporeal membrane oxygenation serves as a crucial mechanical circulatory support for pediatric patients with severe heart diseases, but the mortality rate remains high. The objective of this study was to assess the short-term mortality in these patients. METHODS AND RESULTS We systematically searched PubMed, Embase, and Cochrane Library for observational studies that evaluated the short-term mortality of pediatric patients undergoing veno-arterial extracorporeal membrane oxygenation. To estimate short-term mortality, we used random-effects meta-analysis. Furthermore, we conducted meta-regression and binomial regression analyses to investigate the risk factors associated with the outcome of interest. We systematically reviewed 28 eligible references encompassing a total of 1736 patients. The pooled analysis demonstrated a short-term mortality (defined as in-hospital or 30-day mortality) of 45.6% (95% CI, 38.7%-52.4%). We found a significant difference (P<0.001) in mortality rates between acute fulminant myocarditis and congenital heart disease, with acute fulminant myocarditis exhibiting a lower mortality rate. Our findings revealed a negative correlation between older age and weight and short-term mortality in patients undergoing veno-arterial extracorporeal membrane oxygenation. Male sex, bleeding, renal damage, and central cannulation were associated with an increased risk of short-term mortality. CONCLUSIONS The short-term mortality among pediatric patients undergoing veno-arterial extracorporeal membrane oxygenation for severe heart diseases was 45.6%. Patients with acute fulminant myocarditis exhibited more favorable survival rates compared with those with congenital heart disease. Several risk factors, including male sex, bleeding, renal damage, and central cannulation contributed to an increased risk of short-term mortality. Conversely, older age and greater weight appeared to be protective factors.

Cardiac arrest and cardiopulmonary resuscitation in pediatric patients with cardiac disease: a narrative review. Eur J Pediatr 2023; 182:4289-4308. [PMID: 37336847 PMCID: PMC10909121 DOI: 10.1007/s00431-023-05055-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/15/2023] [Revised: 05/27/2023] [Accepted: 06/02/2023] [Indexed: 06/21/2023]
Abstract
Children with cardiac disease are at a higher risk of cardiac arrest as compared to healthy children. Delivering adequate cardiopulmonary resuscitation (CPR) can be challenging due to anatomic characteristics, risk profiles, and physiologies. We aimed to review the physiological aspects of resuscitation in different cardiac physiologies, summarize the current recommendations, provide un update of current literature, and highlight knowledge gaps to guide research efforts. We specifically reviewed current knowledge on resuscitation strategies for high-risk categories of patients including patients with single-ventricle physiology, right-sided lesions, right ventricle restrictive physiology, left-sided lesions, myocarditis, cardiomyopathy, pulmonary arterial hypertension, and arrhythmias. Cardiac arrest occurs in about 1% of hospitalized children with cardiac disease, and in 5% of those admitted to an intensive care unit. Mortality after cardiac arrest in this population remains high, ranging from 30 to 65%. The neurologic outcome varies widely among studies, with a favorable neurologic outcome at discharge observed in 64%-95% of the survivors. Risk factors for cardiac arrest and associated mortality include younger age, lower weight, prematurity, genetic syndrome, single-ventricle physiology, arrhythmias, pulmonary arterial hypertension, comorbidities, mechanical ventilation preceding cardiac arrest, surgical complexity, higher vasoactive-inotropic score, and factors related to resources and institutional characteristics. Recent data suggest that Extracorporeal membrane oxygenation CPR (ECPR) may be a valid strategy in centers with expertise. Overall, knowledge on resuscitation strategies based on physiology remains limited, with a crucial need for further research in this field. Collaborative and interprofessional studies are highly needed to improve care and outcomes for this high-risk population. What is Known: • Children with cardiac disease are at high risk of cardiac arrest, and cardiopulmonary resuscitation may be challenging due to unique characteristics and different physiologies. • Mortality after cardiac arrest remains high and neurologic outcomes suboptimal. What is New: • We reviewed the unique resuscitation challenges, current knowledge, and recommendations for different cardiac physiologies. • We highlighted knowledge gaps to guide research efforts aimed to improve care and outcomes in this high-risk population.

Abstract
BACKGROUND Mechanical circulatory support (MCS) is a common treatment modality for circulatory failure caused by pediatric myocarditis. Despite improvements in treatment strategy, the mortality rate of pediatric patients with myocarditis treated with MCS is still high. Identifying the factors associated with mortality among pediatric patients with myocarditis treated with MCS may help reduce the mortality rate. METHODS This retrospective cohort study examined the data of patients aged <16 years who were admitted to a hospital between July 2010 and March 2018 for myocarditis; the data were collected from the Diagnosis Procedure Combination database, which is a national inpatient database in Japan. RESULTS During the study period, 105 of the 598 patients with myocarditis were treated with MCS. We excluded seven patients who died within 24 h of admission, resulting in 98 eligible patients. The overall in-hospital mortality was 22 %. In-hospital mortality was higher among patients aged <2 years and those who received cardiopulmonary resuscitation (CPR). Multivariable logistic regression analysis showed significantly higher in-hospital mortality among patients aged <2 years old [odds ratio (OR), 6.57; 95 % confidence interval (CI), 1.89-22.87] and those who received CPR (OR, 4.70; 95 % CI, 1.51-14.63; p < 0.01). CONCLUSION The in-hospital mortality of pediatric patients with myocarditis treated with MCS was high, particularly of children younger than 2 years and those who received CPR.

Abstract
Fulminant myocarditis (FM) is an acute and severe form of myocarditis with rapid progression and poor clinical outcomes in the absence of acute or chronic coronary artery disease. Electrocardiogram (ECG) abnormalities can provide preliminary clues for diagnosis; however, there is a lack of systemic descriptions on ECG changes in FM populations. Thus, a retrospective analysis of 150 consecutive FM patients and 300 healthy controls was performed to determine the characteristic ECG findings in FM. All patients included had markedly abnormal ECG findings. Specifically, 83 (55.33%) patients had significantly lower voltage with remarkably decreased QRS amplitudes in all leads compared with healthy controls (p < 0.01), and 77 (51.33%) patients had a variety of arrhythmias with lethality ventricular tachycardia/ventricular fibrillation in 21 (14.00%) patients and third-degree atrioventricular block in 21 (14.00%) patients, whereas sinus tachycardia was only found in 43 (28.67%) patients with the median heart rate (HR; 88.00 bpm, IQR: 76.00-113.50) higher than that of controls (73.00 bpm, IQR: 68.00-80.00) (p = 0.000). Conduction and repolarization abnormalities were common in patients. A longer QTc interval (452.00 ms, IQR: 419.00-489.50) and QRS duration (94.00 ms, IQR: 84.00-119.00) were observed in patients compared to controls (QTc interval = 399.00 ms, IQR: 386.00-414.00; QRS duration = 90.00 ms, IQR: 86.00-98.00) (p < 0.05). Additionally, HR > 86.50 bpm, QTc > 431.50 ms, and RV5 + SV1 < 1.715 mV can be used to predict FM. Thus, marked and severe ECG abnormalities provide preliminary clues for the diagnosis of FM.

Abstract
AbstractLack of defined diagnostic criteria for acute myocarditis makes its diagnosis dependent on clinical suspicion. The objective of this study was to the current trends in demographics, clinical manifestations, treatments, and outcomes in the United States for children hospitalized with acute myocarditis. This retrospective study was conducted using data collected from the Pediatric Health Information System database for the years 2014 to 2020. We included patients 21 years of age or younger with acute myocarditis. The statistical analysis was performed using chi-squared test and continuous variables using Mann–Whitney's U-test for continuous data comparisons. We found 1,199 patients with acute myocarditis. About 60% of patients required admission to the intensive care unit (ICU). The median hospital length of stay was 4 days for all patients and 6 days for ICU patients. Two hundred sixty-five (22.1%) patients required invasive mechanical ventilation, 127 (10.6%) required extracorporeal membrane oxygenation, 33 (2.8%) required ventricular assist device, and 22 (1.8%) required cardiac transplantations. Milrinone was the most used vasoactive agent. The overall hospital mortality was 2.3%. Intravenous immunoglobulin (IVIG) infusion use decreased during the study period. On multivariate analysis, vasoactive medication use (p < 0.01) and arrhythmia (p = 0.02) were independently associated with increased odds of mortality. IVIG use (p = 0.01) was associated with decreased odds of mortality. Despite high morbidity and frequent need for advanced life support measures, the survival outcomes of acute myocarditis in children are favorable. Vasoactive medication support and occurrence of arrythmia were independently associated with mortality, most likely due to disease severity. Administration of IVIG was independently associated with reduced mortality. The Clinical trial registration is not applicable.

Abstract
Cardiac point-of-care ultrasound has the potential to improve patient care, but its application to children requires consideration of anatomic and physiologic differences from adult populations, and corresponding technical aspects of performance. This document is the product of an American Society of Echocardiography task force composed of representatives from pediatric cardiology, pediatric critical care medicine, pediatric emergency medicine, pediatric anesthesiology, and others, assembled to provide expert guidance. This diverse group aimed to identify common considerations across disciplines to guide evolution of indications, and to identify common requirements and infrastructure necessary for optimal performance, training, and quality assurance in the practice of cardiac point-of-care ultrasound in children. The recommendations presented are intended to facilitate collaboration among subspecialties and with pediatric echocardiography laboratories by identifying key considerations regarding (1) indications, (2) imaging recommendations, (3) training and competency assessment, and (4) quality assurance.

Abstract
OBJECTIVE The study objective is assessing findings and outcome in children with suspected cardiomyopathy (CMP) or myocarditis undergoing cardiac catheterization with transcatheter right ventricular endomyocardial biopsy (RV-EMB). METHODS All consecutive children undergoing cardiac catheterization with RV-EMB for suspected CMP/myocarditis between 2002-2021 were analysed regarding clinical presentation, cardiac biomarkers, periprocedural management, hemodynamic, histological/immunohistological findings, and outcome. RESULTS Eighty-five RV-EMBs were performed in 81 patients at a median age of 6.8 (IQR 9.9) years and a bodyweight of 20 (32.2) kg. Histological/immunohistological findings of RV-EMB revealed dilated CMP in 10 (12%), chronic myocarditis in 28 (33%), healing myocarditis in 5 (6%), acute myocarditis in 9 (11%), other heart muscle diseases in 23 (27%) (7 restrictive CMP, 5 hypertrophic CMP, 4 toxic/anthracycline-induced CMP, 4 endocardfibroelastosis, 1 arrhythmogenic right ventricular CMP, 1 laminin CMP, 1 haemangioma), no conclusive histology in 7 (8%), and normal histology in 3 (4%) patients. Median LVEDP was 17 mmHg (IQR 9), LAP 15 mmHg (10), and PVR 1.83 (1.87) Wood Units/m2. There were 3 major complications (3%), all patients recovered without any sequelae. At follow-up (median 1153, IQR 1799 days) 47 (59%) patients were alive, 11 (13%) dead, 15 (18%) underwent cardiac transplantation, and 8 (9%) were lost to follow-up. Death/cardiac transplantation occurred within 3 years from RV-EMB. All patients with an acute myocarditis survived. NT-pro-BNP, echo parameters, and invasive hemodynamics correlate independently with death/cardiac transplant. CONCLUSION Hemodynamic invasive data and morphological findings in RV-EMB complete clinical diagnosis in children with suspected CMP/myocarditis and provide important information for further clinical management.

Abstract
Myocarditis and/or pericarditis (also known as myopericarditis) are inflammatory diseases involving the myocardium (with non-ischemic myocyte necrosis) and/or the pericardial sac. Myocarditis/pericarditis (MPC) may present with variable clinical signs, symptoms, etiologies and outcomes, including acute heart failure, sudden death, and chronic dilated cardiomyopathy. Possible undiagnosed and/or subclinical acute myocarditis, with undefined potential for delayed manifestations, presents further challenges for diagnosing an acute disease and may go undetected in the setting of infection as well as adverse drug/vaccine reactions. The most common causes of MPC are viral, with non-infectious, drug/vaccine associated hypersensitivity and/or autoimmune causes being less well defined and with potentially different inflammatory mechanisms and treatment responses. Potential cardiac adverse events following immunization (AEFIs) encompass a larger scope of diagnoses such as triggering or exacerbating ischemic cardiac events, cardiomyopathy with potential heart failure, arrhythmias and sudden death. The current published experience does not support a potential causal association with vaccines based on epidemiologic evidence of relative risk increases compared with background unvaccinated incidence. The only evidence supporting a possible causal association of MPC with a vaccine comes from case reports. Hypersensitivity MPC as a drug/vaccine induced cardiac adverse event has long been a concern for post-licensure safety surveillance, as well as safety data submission for licensure. Other cardiac adverse events, such as dilated cardiomyopathy, were also defined in the CDC definitions for adverse events after smallpox vaccination in 2006. In addition, several groups have attempted to develop and improve the definition and adjudication of post-vaccination cardiovascular events. We developed the current case definitions for myocarditis and pericarditis as an AEFI building on experience and lessons learnt, as well as a comprehensive literature review. Considerations of other etiologies and causal relationships are outside the scope of this document.

Abstract
Acute Flaccid Myelitis is defined by the presence of Acute Flaccid Paralysis (AFP) and a spinal cord lesion on magnetic resonance imaging that is primarily limited to the grey matter. AFM is a difficult situation to deal with when you have a neurologic illness. According to the Centers for Disease Control and Prevention (CDC), a large number of cases were discovered in the United States in 2014, with 90% of cases occurring in children. Although the exact cause of AFM is unknown, mounting evidence suggests a link between AFM and enterovirus D68 (EV-D68). In 2014, an outbreak of AFM was discovered in the United States. The condition was initially linked to polioviruses; however, it was later found that the viruses were caused by non-polioviruses Enteroviruses D-68 (EV-D68). The number of cases has increased since 2014, and the disease has been declared pandemic in the United States. The sudden onset of muscle weakness, usually in an arm or leg, as well as pain throughout the body, the change in patient's facial expression (facial weakness), and shortness of breath, ingesting, and speaking are all common symptoms in patients suffering from neurologic disease. This article includes graphic and histogram representations of reported AFM incidents and criteria for causality, epidemiology, various diagnostic approaches, signs and symptoms, and various investigational guidelines. It also includes key statements about recent clinical findings related to AFM disease.

Abstract
Introduction Myocarditis remains an under-diagnosed entity among children. We evaluated the spectrum of electrocardiogram (ECG) changes and arrhythmias in children with myocarditis. Methods A single-center prospective observational study was conducted over a period of 18 months at a public university hospital, which included all cases with myocarditis from the ages of 1 month to 12 years. Myocarditis was diagnosed according to standard criteria. Arrhythmias were detected by 12-lead ECG or by multiparameter monitors. Results There were 63 children with myocarditis. Sinus tachycardia remained the most important ECG finding (61, 96.8%) followed by ST-T changes (30, 47.6%), low voltage QRS complexes (23, 36.5%), and premature complexes (11, 17.4%). Sustained arrhythmias were seen in 14/63 (22.2%) of the children (Group A), while the remaining 49 patients were designated as Group B. There were 11 (17.5%) cases with sustained tachyarrhythmias, comprising 5 with supraventricular tachycardia, 4 with ventricular tachycardia, and 2 with atrial flutter/fibrillation. Bradyarrhythmias were seen in 3 patients, including 2 children with atrioventricular block and 1 with severe sinus bradycardia. A longer hospital stay of 18.5 (4.75) days vs. 13 (4) days, P = 0.001), and more ST-T changes [12 (85.7%) vs. 18 (36.73%), P = 0.003] were seen in Group A. Multivariate regression analysis found only the presence of ST-T changes as predictors for arrhythmia. Conclusions A variety of arrhythmias and other ECG changes were commonly seen in children with myocarditis. Sustained arrhythmias were seen in one-fifth of the patients, being associated with ST-T changes and a longer hospital stay.

Abstract
Myocarditis is an inflammatory condition of the myocardium and is usually categorised as acute nonfulminant and acute fulminant myocarditis. Myocardial injury can result via viral infections, direct injury or immune responses. Fulminant myocarditis can be characterised by severe and sudden cardiac inflammation that may result from cardiogenic shock, ventricular arrhythmias or multi-organ system failure. Extracorporeal membrane oxygenation (ECMO), also known as extracorporeal life support, is an effective technique for patients with fulminant myocarditis, providing heart and lung support and adequate gas exchange or perfusion to sustain life. Essentially, ECMO pumps blood out of the body to an oxygenator that acts as an artificial lung, which adds oxygen to the blood and removes carbon dioxide. This report aims to review recent advances in ECMO and relate case studies of fulminant myocarditis patients. The types of ECMO, predictive factors for success, clinical studies and recent technological advances in the field will be discussed.

Abstract
Acute fulminant myocarditis (AFM) occurs as an inflammatory response to an initial myocardial insult. Its rapid and deadly progression calls for prompt diagnosis with aggressive treatment measures. The demonstration of its excellent recovery potential has led to increasing use of mechanical circulatory support, especially extracorporeal membrane oxygenation (ECMO). Arrhythmias, organ failure, elevated cardiac biomarkers, and decreased ventricular function at presentation predict requirement for ECMO. In these patients, ECMO should be considered earlier as the clinical course of AFM can be unpredictable and can lead to rapid haemodynamic collapse. Key uncertainties that clinicians face when managing children with AFM such as timing of initiation of ECMO and left ventricular decompression need further investigation.

Abstract
In children with severe advanced heart failure where medical management has failed, mechanical circulatory support in the form of veno-arterial extracorporeal membrane oxygenation (VA ECMO) or ventricular assist device represents life-sustaining therapy. This review provides an overview of VA ECMO used for cardiovascular support including medical and surgical heart disease. Indications, contraindications, and outcomes of VA ECMO in the pediatric population are discussed.VA ECMO provides biventricular and respiratory support and can be deployed in rapid fashion to rescue patient with failing physiology. There have been advances in conduct and technologic aspects of VA ECMO, but survival outcomes have not improved. Stringent selection and optimal timing of deployment are critical to improve mortality and morbidity of the patients supported with VA ECMO.

Abstract
Children affected with acute myocarditis may progress rapidly into profound ventricular dysfunction and ventricular arrhythmias. The objective of this study is to assess the impact of ventricular arrhythmias on in-hospital mortality and the use of mechanical circulatory support in patients with myocarditis. Pediatric patients (age 0-18 years) admitted with myocarditis were identified from the National Inpatient Sample dataset for the years 2002-2015. A total of 12,489 patients with myocarditis were identified. Of them, 1627 patients were with ventricular arrhythmias and 10,862 patients without ventricular arrhythmias. Mortality was higher in those with ventricular arrhythmias (19.5% vs. 2.8%, OR = 8.47; 95% CI 7.16-10.04; p < 0.001). The median length of stay and the median cost of hospitalization were higher in the ventricular arrhythmias group (9 days vs. 4 days, p < 0.001 and $121,826 vs. $37,658, p < 0.001, respectively). There was a substantial increase in the utilization of extracorporeal membrane oxygenation (ECMO) in patients with ventricular arrhythmias (25.4% vs. 2.7%, OR = 12.40; 95% CI 10.55-14.57; p < 0.001). The use of ventricular assist devices (VADs) was higher in patients with ventricular arrhythmias (4.5% vs. 1.3%, OR = 3.76; 95% CI 2.82-5.01; p < 0.001). An improvement in discharge survival was observed over the years of study in both VA and non-VA groups; associated with this decline in mortality, there was a rising trend of ECMO utilization.Conclusion: Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. What is Known: • The clinical presentation of pediatric myocarditis varies from no symptoms of myocardial dysfunction to a rapidly progressing severe congestive heart failure. • Little is known about the predictors of mortality in children with suspected myocarditis. What is New: • Development of ventricular arrhythmia in children with myocarditis is a strong predictor for mortality and ECMO utilization. • Improvement in discharge survival was observed over the years of study; associated with this decline in mortality, there was a rising trend of ECMO utilization.

Abstract
OBJECTIVE To determine prevalence of and risk factors for infection in pediatric subjects with congenital heart disease status postcardiotomy supported on extracorporeal membrane oxygenation, as well as outcomes of these subjects. DESIGN Retrospective cohort from the Extracorporeal Life Support Organization. SETTING U.S. and international medical centers providing care to children with congenital heart disease status postcardiotomy. PATIENTS Critically ill pediatric subjects less than 8 years old admitted to medical centers between January 1, 2013, and December 31, 2015, who underwent cardiac surgery for congenital heart disease and required extracorporeal membrane oxygenation support within the first 14 postoperative days. Subjects were excluded if they underwent orthotopic heart transplantation, required preoperative extracorporeal membrane oxygenation, and had more than one postoperative extracorporeal membrane oxygenation run. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS A total of 1,314 extracorporeal membrane oxygenation subject encounters in the Extracorporeal Life Support Organization registry met inclusion criteria. Neonates comprised 53% (n = 696) of the cohort, whereas infants made up 33% (n = 435). Of the 994 subjects with Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery categorizable surgery, 33% (n = 325) were in Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery category 4 and 23% (n = 231) in Society of Thoracic Surgeons-European Association for Cardio-Thoracic Surgery category 5. While on extracorporeal membrane oxygenation, 229 subjects (17%) acquired one or more extracorporeal membrane oxygenation-related infections, which represents an occurrence rate of 67 infections per 1,000 extracorporeal membrane oxygenation days. Gram-negative (62%) and Gram-positive (42%) infections occurred most commonly. Forty percent had positive blood cultures. Infants and children were at higher infection risk compared with neonatal subjects; subjects undergoing less complex surgery had higher infection rates. Unadjusted survival to hospital discharge was lower in infected subjects compared with noninfected subjects (43% vs 51%; p = 0.01). After adjusting for confounders via propensity matching, we identified no significant mortality difference between infected and noninfected subjects. CONCLUSIONS Neonatal and pediatric subjects in this study have a high rate of acquired infection. Infants and children were at higher infection risk compared with neonatal subjects. There was not, however, a significant association between extracorporeal membrane oxygenation-related infection and survival to hospital discharge after propensity matching.

[PMID: 31493782 PMCID: PMC6731567 DOI: 10.1186/s12887-019-1695-0] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/09/2019] [Accepted: 08/26/2019] [Indexed: 12/12/2022] Open
Abstract
Background and aims Few data are currently available for Kawasaki disease (KD) below 12 months especially in Caucasians. This study aims to analyze clinical and laboratory features of KD among an Italian cohort of infants. Methods A retrospective chart review of KD children aged less than 1 year at time of disease onset between January 2008–December 2017 was performed. Clinical data, laboratory parameters, instrumental findings, treatment and outcome were collected in a customized database. Results Among 113 KD patients, 32 (28.3%) were younger than 1 year. Nineteen patients aged below 6 months, and three below 3 months. The median age was 5.7 ± 2.7 months. The mean time to diagnosis was 7 ± 3 days and was longer in the incomplete forms (8 ± 4 vs 6 ± 1 days). Conjunctival injection was present in 26 patients (81.2%); rash in 25 (78.1%); extremity changes in 18 (56.2%); mucosal changes in 13 (40.6%,) and lymphadenopathy only in 7 (21.8%). Mucosal changes were the least common features in incomplete forms (18.2%). Twenty-two patients (68.7%) had incomplete KD. Nineteen (59.4%) had cardiac involvement, of whom 13 (59.0%) had incomplete form. ESR, PCR and platelet values were higher in complete KD; especially, ESR resulted significantly higher in complete forms (80 ± 25.7 mm/h vs 50 ± 28.6 mm/h; p = 0.01). Conversely, AST level was statistically significant higher in patients with incomplete forms (95.4 ± 132.7 UI/L vs 29.8 ± 13.2 UI/L; p = 0.03). All patients received IVIG. Response was reported in 26/32 patients; 6 cases needed a second dose of IVIG and one required a dose of anakinra. Conclusion In our cohort, incomplete disease was commonly found, resulting in delayed diagnoses and poor cardiac prognosis. Infants with incomplete KD seem to have a more severe disease and a greater predilection for coronary involvement than those with complete KD. AST was significantly higher in incomplete forms, thus AST levels might be a new finding in incomplete forms’ diagnosis. Eventually, we highlight a higher resistance to IVIG treatment. To our knowledge this is the first study involving an Italian cohort of patients with KD below 12 months.

Role of intravenous immunoglobulin therapy in the survival rate of pediatric patients with acute myocarditis: A systematic review and meta-analysis. Sci Rep 2019; 9:10459. [PMID: 31320679 PMCID: PMC6639391 DOI: 10.1038/s41598-019-46888-0] [Citation(s) in RCA: 24] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/31/2018] [Accepted: 07/08/2019] [Indexed: 01/16/2023] Open
Abstract
The treatment of pediatric myocarditis is controversial, and the benefits of intravenous immunoglobulin (IVIG) are inconclusive due to limited data. We searched studies from PubMed, MEDLINE, Embase, and Cochrane Library databases since establishment until October 1st, 2018. Thirteen studies met the inclusion criteria. We included a total of 812 patients with IVIG treatment and 592 patients without IVIG treatment. The meta-analysis showed that the survival rate in the IVIG group was higher than that in the non-IVIG group (odds ratio = 2.133, 95% confidence interval (CI): 1.32-3.43, p = 0.002). There was moderate statistical heterogeneity among the included studies (I2 = 35%, p = 0.102). However, after adjustment using Duval and Tweedie's trim and fill method, the point estimate of the overall effect size was 1.40 (95% CI 0.83, 2.35), which became insignificant. Moreover, the meta-regression revealed that age (coefficient = -0.191, 95% CI (-0.398, 0.015), p = 0.069) and gender (coefficient = 0.347, 95% CI (-7.586, 8.279), p = 0.93) were not significantly related to the survival rate. This meta-analysis showed that IVIG treatment was not associated with better survival. The use of IVIG therapy in acute myocarditis in children cannot be routinely recommended based on current evidence. Further prospective and randomized controlled studies are needed to elucidate the effects of IVIG treatment.

Abstract
BACKGROUND The clinical spectrum of pediatric acute myocarditis ranges from minimal symptoms with intact hemodynamics to rapid cardiovascular collapse and death. We sought to identify factors on initial presentation associated with subsequent hemodynamic compromise. METHODS We performed a retrospective cohort study of patients with acute myocarditis at a freestanding pediatric hospital from 2007 to 2016. We defined 2 cohorts: high-acuity patients with hemodynamic compromise defined as requiring inotropic or vasoactive medications, cardiopulmonary resuscitation, extracorporeal membrane oxygenation, ventricular assist devices, or transplant or who died and low-acuity patients without these interventions. We collected the first recorded set of vital signs, symptoms, laboratory values, and chest radiograph, electrocardiogram, and echocardiography results. Univariate analysis was performed, and 2 multivariable logistic regression models were created to discriminate between cohorts. RESULTS A total of 74 patients were included: 33 high acuity and 41 low acuity. There were significant differences in demographics, symptoms, and physical examination, laboratory, electrocardiogram, and echocardiography findings between high- and low-acuity cohorts. Multivariable logistic regression models were highly discriminate in predicting those in the high-acuity cohort. The first model included presence of tachycardia, tachypnea, creatinine, and cardiomegaly on chest radiograph (area under the curve = 0.913). The second model added the presence of pericardial effusion to the above variables (area under the curve = 0.964). CONCLUSIONS Models based on factors available at initial presentation with acute myocarditis are predictive of subsequent hemodynamic compromise. If our results can be validated in a multicenter study, these models may help disposition patients with suspected acute myocarditis (with those who meet model criteria being admitted to centers capable of rapidly providing extracorporeal membrane oxygenation, ventricular assist devices, and heart transplant evaluation).

Abstract
Children with myocarditis have increased risk of ventricular tachycardia (VT) due to myocardial inflammation and remodeling. There is currently no accepted method for VT risk stratification in this population. We hypothesized that personalized models developed from cardiac late gadolinium enhancement magnetic resonance imaging (LGE-MRI) could determine VT risk in patients with myocarditis using a previously-validated protocol. Personalized three-dimensional computational cardiac models were reconstructed from LGE-MRI scans of 12 patients diagnosed with myocarditis. Four patients with clinical VT and eight patients without VT were included in this retrospective analysis. In each model, we incorporated a personalized spatial distribution of fibrosis and myocardial fiber orientations. Then, VT inducibility was assessed in each model by pacing rapidly from 26 sites distributed throughout both ventricles. Sustained reentrant VT was induced from multiple pacing sites in all patients with clinical VT. In the eight patients without clinical VT, we were unable to induce sustained reentry in our simulations using rapid ventricular pacing. Application of our non-invasive approach in children with myocarditis has the potential to correctly identify those at risk for developing VT.

Abstract
Pediatric myocarditis symptoms can be mild or as extreme as sudden cardiac arrest. Early identification of the severity of illness and timely provision of critical care is helpful; however, the risk factors associated with mortality remain unclear and controversial. We undertook a retrospective review of the medical records of pediatric patients with myocarditis in a tertiary care referral hospital for over 12 years to identify the predictive factors of mortality. Demographics, presentation, laboratory test results, echocardiography findings, and treatment outcomes were obtained. Regression analyses revealed the clinical parameters for predicting mortality. During the 12-year period, 94 patients with myocarditis were included. Of these, 16 (17%) patients died, with 12 succumbing in the first 72 hours after admission. Fatal cases more commonly presented with arrhythmia, hypotension, acidosis, gastrointestinal symptoms, decreased left ventricular ejection fraction, and elevated isoenzyme of creatine kinase and troponin I levels than nonfatal cases. In multivariate analysis, troponin I > 45 ng/mL and left ventricular ejection fraction < 42% were significantly associated with mortality. Pediatric myocarditis had a high mortality rate, much of which was concentrated in the first 72 hours after hospitalization. Children with very high troponin levels or reduced ejection fraction in the first 24 hours were at higher risk of mortality, and targeting these individuals for more intensive therapies may be warranted.

Abstract
Myocarditis is an inflammatory disease of the myocardium with a broad spectrum of clinical presentations, ranging from mild symptoms to severe heart failure. The course of patients with myocarditis is heterogeneous, varying from partial or full clinical recovery in a few days to advanced low cardiac output syndrome requiring mechanical circulatory support or heart transplantation. Myocarditis is a very heterogeneous disease, especially in the pediatric age group as worldwide disease myocarditis has been defined by the World Health Organization/International Society and Federation of Cardiology as an inflammatory disease of the heart muscle diagnosed by established histological, immunologic, and immunohistological criteria. Pediatric myocarditis remains challenging from the perspectives of diagnosis and management. Multiple etiologies exist, and the majority of cases appear to be related to viral illnesses. Enteroviruses are believed to be the most common cause, although cases related to adenovirus may be more frequent than suspected. The clinical presentation is extremely varied, ranging from asymptomatic to sudden unexpected death. A high index of suspicion is crucial. There is emerging evidence to support investigations such as serum N-terminal B-type natriuretic peptide levels, as well as cardiac magnetic resonance imaging as adjuncts to the clinical diagnosis. In the future, these may reduce the necessity for invasive methods, such as endomyocardial biopsy, which remain the gold standard. Management generally includes supportive care, consisting of cardiac failure medical management, with the potential for mechanical support and cardiac transplantation. Treatments aimed at immunosuppression remain controversial. The paediatrics literature is extremely limited with no conclusive evidence to support or refute these strategies. All these summarised in this article and the listed current literature showed that there is no consensus regarding aetiology, clinical presentation, diagnosis, and management of myocarditis in pediatric patients.

Abstract
Worldwide, the use of Extracorporeal Membrane Oxygenation (ECMO) for cardiac failure has been steadily increasing in the neonatal population and has become a widely accepted modality. Especially in centers caring for children with (congenital) heart disease, ECMO is now an essential part of care available for those with severe heart failure as a bridge to recovery, long term mechanical support, or transplantation. Short-term outcomes depend very much on indication. Hospital survival is ~40% for all neonatal cardiac ECMO patients combined. ECMO is being used for pre- and/or post-operative stabilization in neonates with congenital heart disease and in neonates with medical heart disease such as myocarditis, cardiomyopathy or refractory arrhythmias. ECMO use during resuscitation (ECPR) or for sepsis is summarized elsewhere in this special edition of Frontiers in Pediatrics. In this review article, we will discuss the indications for neonatal cardiac ECMO, the difficult process of patients' selection and identifying the right timing to initiate ECMO, as well as outline pros and cons for peripheral vs. central cannulation. We will present predictors of mortality and, very importantly, predictors of survival: what can be done to improve the outcomes for your patients. Furthermore, an overview of current insights regarding supportive care in neonatal cardiac ECMO is given. Additionally, we will address issues specific to neonates with single ventricle physiology on ECMO, for example cannulation strategies and the influence of shunt type (Blalock-Taussig shunt vs. "right ventricle to pulmonary artery" shunt). We will not only focus on short term outcomes, such as hospital survival, but also on the importance of long-term neuro-developmental outcomes, and we will end this review with suggestions for future research.

Abstract
Serum troponin (Tn) is often elevated in viral myocarditis; however, its prognostic significance is unknown. We tested the hypothesis that abnormal serum Tn is associated with mortality in children hospitalized with myocarditis. We retrospectively studied data from six large children's hospitals participating in the Pediatric Health Information System Plus (PHIS+) database. Analysis was performed on patients hospitalized with viral myocarditis between 2007 and 2013, in whom at least one Tn was recorded within 72 h of admission. Abnormal baseline Tn was defined as any value outside the upper limit of normal within the first 72 h. Primary outcome was mortality. Secondary outcomes included mechanical support, defined as use of extracorporeal membrane oxygenation (ECMO) or a ventricular assist device (VAD), cardiac transplantation, intravenous immunoglobulin (IVIg), mechanical ventilation, and inotrope use. A total of 149 patients with myocarditis (61% male, 48% adolescents) across all PHIS+ centers had TnI (n = 113) or TnT (n = 36) recorded. At least one abnormal Tn was present in 81% of cases. Overall mortality was 7.3% and was not associated with abnormal baseline Tn. Abnormal baseline Tn was associated with ECMO (7.1 vs. 25.6%, p = 0.03) and IVIg (46.4 vs. 83.5%, p < 0.001). Abnormal baseline Tn was not associated with transplantation, mechanical ventilation or inotrope use. Abnormal Tn in the first 72 h of hospitalization for myocarditis was associated with the use of ECMO and IVIg, but was not associated with mortality. This finding may help risk stratify this population if it can be prospectively validated.

Abstract
OBJECTIVE To describe the effect of extracorporeal membrane oxygenation (ECMO) on survival and cardiac outcome of neonates with myocardial failure secondary to severe enterovirus (EV) myocarditis. DESIGN Retrospective case series. SETTING A 15-bed cardiac paediatric intensive care unit (ICU). PATIENTS We describe the clinical presentations, cardiac findings, ECMO characteristics and outcome of seven neonates with severe EV myocarditis. Additionally, 35 previously reported cases of EV myocarditis supported with ECMO are presented. INTERVENTIONS Extracorporeal membrane oxygenation. RESULTS Seven neonates presented with cardiovascular collapse within the first 10 days after birth and required ECMO support. Echocardiography showed left ventricular dysfunction in all and additional right ventricular dysfunction in four patients. ECG showing widespread ST changes as well as elevated troponin I indicated myocardial damage. All patients were cannulated onto ECMO shortly after ICU admission. None of the patients suffered cardiac arrest prior to ECMO initiation. Four patients survived ECMO and three survived to hospital discharge. All three survivors showed complete cardiac recovery after a median follow-up of 34 months. The survival rate in 35 previously reported cases was 34% (12/35) and including our seven cases 36% (15/42). CONCLUSIONS In this case series, ECMO initiation prevented further deterioration and cardiac arrest in neonates with severe EV myocarditis and not responding to conventional medical therapies. Moreover, complete cardiac recovery occurred in survivors. However, these neonates may need long ECMO runs and are at increased risk for mechanical complications. Furthermore, mortality remains high due to greater disease severity.

Abstract
OBJECTIVES Cardiopulmonary failure in children with cardiac disease differs from the general pediatric critical care population, yet the epidemiology of extracorporeal membrane oxygenation support in cardiac ICUs has not been described. We aimed to characterize extracorporeal membrane oxygenation utilization and outcomes across surgical and medical patients in pediatric cardiac ICUs. DESIGN Retrospective analysis of the Pediatric Cardiac Critical Care Consortium registry to describe extracorporeal membrane oxygenation frequency and outcomes. Within strata of medical and surgical hospitalizations, we identified risk factors associated with extracorporeal membrane oxygenation use through multivariate logistic regression. SETTING Tertiary-care children's hospitals. PATIENTS Neonates through adults with cardiac disease. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS There were 14,526 eligible hospitalizations from August 1, 2014, to June 30, 2016; 449 (3.1%) included at least one extracorporeal membrane oxygenation run. Extracorporeal membrane oxygenation was used in 329 surgical (3.5%) and 120 medical (2.4%) hospitalizations. Systemic circulatory failure and extracorporeal cardiopulmonary resuscitation were the most common extracorporeal membrane oxygenation indications. In the surgical group, risk factors associated with postoperative extracorporeal membrane oxygenation use included younger age, extracardiac anomalies, preoperative comorbidity, higher Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery category, bypass time, postoperative mechanical ventilation, and arrhythmias (all p < 0.05). Bleeding requiring reoperation (25%) was the most common extracorporeal membrane oxygenation complication in the surgical group. In the medical group, risk factors associated with extracorporeal membrane oxygenation use included acute heart failure and higher Vasoactive Inotropic Score at cardiac ICU admission (both p < 0.0001). Stroke (15%) and renal failure (15%) were the most common extracorporeal membrane oxygenation complications in the medical group. Hospital mortality was 49% in the surgical group and 63% in the medical group; mortality rates for hospitalizations including extracorporeal cardiopulmonary resuscitation were 50% and 83%, respectively. CONCLUSIONS This is the first multicenter study describing extracorporeal membrane oxygenation use and outcomes specific to the cardiac ICU and inclusive of surgical and medical cardiac disease. Mortality remains high, highlighting the importance of identifying levers to improve care. These data provide benchmarks for hospitals to assess their outcomes in extracorporeal membrane oxygenation patients and identify unique high-risk subgroups to target for quality initiatives.

OBJECTIVES Pediatric cardiac intensive care continues to evolve, with rapid advances in knowledge and improvement in clinical outcomes. In the past, the Board of Directors of the Pediatric Cardiac Intensive Care Society created and subsequently updated a list of sentinel references focused on the care of critically ill children with congenital and acquired heart disease. The objective of this article is to provide clinicians with a compilation and brief summary of updated and useful references that have been published since 2012. DATA SELECTION Pediatric Cardiac Intensive Care Society members were solicited via a survey sent out between March 20, 2017, and April 28, 2017, to provide important references that have impacted clinical care. The survey was sent to approximately 523 members. Responses were received from 45 members, of which some included multiple references. DATA EXTRACTION Following review of the list of references, and removing editorials, references were compiled by the first and last author. The final list was submitted to members of the society's Research Briefs Committee, who ranked each publication. DATA SYNTHESIS Rankings were compiled and the references with the highest scores included. Research Briefs Committee members ranked the articles from 1 to 3, with one being highly relevant and should be included and 3 being less important and should be excluded. Averages were computed, and the top articles included in this article. The first (K.C.U.) and last author (K.M.G.) reviewed and developed summaries of each article. CONCLUSIONS This article contains a compilation of useful references for the critical care of children with congenital and acquired heart disease published in the last 5 years. In conjunction with the prior version of this update in 2012, this article may be used as an educational reference in pediatric cardiac intensive care.

Abstract
Neonatal cardiogenic shock most commonly occurs due to critical congenital heart disease, sepsis, metabolic disorder or arrhythmias. In particular, enterovirus infections are common in the neonatal period, and patients can present with fulminant myocarditis. Early recognition is imperative due to its high morbidity and mortality without prompt and aggressive treatment. We present the successful treatment of fulminant neonatal enteroviral myocarditis in a pair of monochorionic diamniotic twins with cardiopulmonary support, intravenous immunoglobulin and pocapavir, an enteroviral capsid inhibitor. The twins took an almost exact parallel hospital course, including day of extracorporeal membrane oxygenation (ECMO) cannulation, day of ECMO decannulation, improvement of cardiac function, discharge and status at follow-up. While it was difficult to assess the relative contribution of each intervention, our case shows promise in the use of pocapavir for treatment of severe enteroviral infections. Remarkably, both twins demonstrated remarkable recovery within 2 weeks, underscoring that early aggressive cardiopulmonary support, and potentially pocapavir, contributed to their recovery.

Abstract
Cardiac arrest occurs at a higher rate in children with heart disease than in healthy children. Pediatric basic life support and advanced life support guidelines focus on delivering high-quality resuscitation in children with normal hearts. The complexity and variability in pediatric heart disease pose unique challenges during resuscitation. A writing group appointed by the American Heart Association reviewed the literature addressing resuscitation in children with heart disease. MEDLINE and Google Scholar databases were searched from 1966 to 2015, cross-referencing pediatric heart disease with pertinent resuscitation search terms. The American College of Cardiology/American Heart Association classification of recommendations and levels of evidence for practice guidelines were used. The recommendations in this statement concur with the critical components of the 2015 American Heart Association pediatric basic life support and pediatric advanced life support guidelines and are meant to serve as a resuscitation supplement. This statement is meant for caregivers of children with heart disease in the prehospital and in-hospital settings. Understanding the anatomy and physiology of the high-risk pediatric cardiac population will promote early recognition and treatment of decompensation to prevent cardiac arrest, increase survival from cardiac arrest by providing high-quality resuscitations, and improve outcomes with postresuscitation care.

Abstract
Myocarditis is an inflammatory disease of the myocardium with a broad spectrum of clinical presentations, ranging from mild symptoms to severe heart failure. The course of patients with myocarditis is heterogeneous, varying from partial or full clinical recovery in few days to advanced low cardiac output syndrome requiring mechanical circulatory support or heart transplantation. Fulminant myocarditis (FM) is a peculiar clinical condition and is an acute form of myocarditis, whose main characteristic is a rapidly progressive clinical course with the need for hemodynamic support. Despite the common medical belief of the past decades, recent comprehensive data, including a recent registry that compared FM with acute non-FM, highlighted that FM has a poor inhospital outcome, often requires advanced hemodynamic support, and may result in residual left ventricular dysfunction in survivors. This review aimed to provide an updated practical definition of FM, including essentials in the diagnosis and management of the disease. Finally, the outcome of FM was critically revised according to the current published registries focusing on the topic.

Abstract
Fulminant myocarditis is a severe cardiac emergency that may lead to death if effective cardiopulmonary supports are not provided. This study aimed to evaluate the prognostic predictors in patients with fulminant myocarditis.We retrospectively analyzed the clinical characteristics, complications, laboratory findings, treatments, as well as electrocardiographic and echocardiographic data of 73 consecutive subjects diagnosed with fulminant myocarditis from June 2012 to June 2016. Logistic regression analysis was used to identify the independent predictive factors of nonsurvivor fulminant myocarditis.Ten patients and 63 patients were assigned to the nonsurvivor and survivor fulminant myocarditis groups, respectively. Patients in the nonsurvivor fulminant myocarditis group had higher heart rates; were more likely to develop clinical complications and supraventricular tachycardia (SVT); and had higher serum creatinine (Scr) level, and had higher white blood cell (WBC) counts, and lower abbreviated estimated glomerular filtration rates (eGFR) than the patients in the survivor fulminant myocarditis group. Moreover, we observed larger left atrium dimension (LAd), larger left ventricular end systolic dimensions, and lower left ventricular ejection fraction in the patients from the nonsurvivor fulminant myocarditis group than in those from the other group. A logistic regression model was constructed and demonstrated that eGFR and LAd were 2 independent predictors of mortality in patients with fulminant myocarditis.Higher heart rates, higher incidences of clinical complication, SVT, higher admission levels of Scr and eGFR, higher WBC counts, higher Scr and eGFR at stage of most severe renal damage, and abnormal echocardiographic findings were associated with high risk of mortality in patients with fulminant myocarditis. The major finding was that eGFR and LAd were independent predictors for in-hospital mortality in patients with fulminant myocarditis.

Abstract
The use of extracorporeal support after failed return of a spontaneous ciruculation during cardiopulmonary resuscitation (ECPR) is well described. There are 4 distinct phases for resuscitation with ECPR and the time spent in each phase is critical for successful outcome. Recommendations for ECPR previously published by the American Heart Association provide the context for implementing a consistent and well-rehearsed system for ECPR, by people with the knowledge, experience and resources to deploy ECPR in the most optimal time frame possible in selected patient populations. In this manuscript we review the current status of ECPR for acute cardiac failure and the components we believe are necessary to develop and sustain a reliable and resilient program.

Abstract
OBJECTIVES Acute myocarditis can be lethal, but the incidence remains unclear because of its wide manifestation spectrum. We investigated the postnatal incidence of acute myocarditis and risk factors for morbidity and mortality. DESIGN Retrospective derived birth cohort study. SETTING Taiwan National Health Insurance Database for the period 2000-2014. PATIENTS Children born between 2000 and 2009 with complete postnatal medical care data for at least 5 years. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS From among 2,150,590 live births, we identified 965 patients (54.8% male) admitted with the diagnosis of acute myocarditis, accounting for an overall incidence of 0.45/1,000. The cumulative incidence rates were 0.19/1,000, 0.38/1,000, 0.42/1,000, and 0.48/1,000 by ages 1, 5, 10, and 15 years, respectively. Male predominance was noted in infants and school age children (age group 6-14 yr). Arrhythmias, including tachyarrhythmia (4.8%) and bradyarrhythmia (1.1%), occurred in 56 patients. Extracorporeal membrane oxygenation support was provided to 62 patients (6.4%) and additional left ventricular assist devices in six of them. The mortality at discharge was 6.3%. The presence of ventricular tachyarrhythmia, bradyarrhythmia, and an onset at school age (6-14 yr) were associated with increased odds for the need for extracorporeal membrane oxygenation, which was the only predictor for mortality at discharge (hazard ratio, 7.85; 95% CI, 3.74-9.29). In patients who survived the acute myocarditis, late mortality was relatively low (36/904 = 4.0%). The overall survival of children with acute myocarditis were 90.9%, 90.3%, and 89.8% by the intervals of 1, 5, and 10 years after the myocarditis, respectively. CONCLUSIONS This birth cohort study determined the cumulative incidence of acute myocarditis for neonates by 15 years old to be one in 2,105. In an era of extracorporeal membrane oxygenation, the need of extracorporeal membrane oxygenation may reflect the severity of acute myocarditis and predict its outcome.

Abstract
BACKGROUND Our study aimed to summarize the clinical outcomes of extracorporeal membrane oxygenation (ECMO) in adult patients with acute fulminant myocarditis and to investigate the risk factors associated with its application. PATIENTS AND METHODS We retrospectively examined patients with cardiogenic shock and acute fulminant myocarditis. The following data were collected: patients' preoperative general condition, related clinical factors during ECMO, complications, and outcomes of ECMO. The patients were divided into a survivor group and a nonsurvivor group. RESULTS From a total of 33 patients, seven died in hospital. The survival rate was 78.7%. The following complications were observed during ECMO: 16 cases of acute renal failure (48.4%), seven cases of sepsis (21.2%), six cases of pulmonary infection (18.1%), six cases of multiple organ failure (MOF; 18.1%), three cases of cerebral hemorrhage (9%), and four cases of limb ischemia (12.1%). Pre-ECMO cardiopulmonary resuscitation, high levels of lactic acid, high amounts of blood transfusion during ECMO, renal failure, encephalorrhagia, gastrointestinal complications, lower-limb ischemia, high bilirubin levels, and MOF during ECMO were associated with unfavorable patient outcomes. CONCLUSION ECMO is an effective auxiliary tool for treating acute fulminant myocarditis. Acute renal failure is the most common complication during ECMO. Improving tissue perfusion, reducing blood transfusions, and preventing acute kidney failure may improve patient outcomes.

Abstract
Fulminant myocarditis is severe and aggressive, but it is self-limited and usually has a favorable prognosis if the patients can survive the acute phase. When drug treatment is not effective, extracorporeal membrane oxygenation technology should be applied to support cardiopulmonary function. Extracorporeal membrane oxygenation can simultaneously support function of the left ventricle, right ventricle, and lungs, and provide stable blood circulation for patients with heart and respiratory failure, which allows sufficient time for the cardiopulmonary system to recover. Fulminant myocarditis affects cardiac systolic function, as well as the function of autorhythmic cells and the conduction system. If severe bradycardia or atrioventricular block appears, a pacemaker needs to be installed. We report a child with fulminant myocarditis who was treated with extracorporeal membrane oxygenation combined with an artificial pacemaker.

Abstract
In this study, we sought predictors of mortality in children with acute myocarditis and of incomplete recovery in the survivor group. We classified our patients into three groups according to their outcomes at last follow-up: full recovery was classified as group I, incomplete recovery was classified as group II, and death was classified as group III. In total, 55 patients were enrolled in the study: 33 patients in group I, 11 patients in group II, and 11 patients in group III. The initial left ventricular fractional shortening - left ventricular fractional shortening - was significantly lower in group III (p=0.001), and the left ventricular end-diastolic dimension z score was higher in groups II and III compared with group I (p=0.000). A multivariate analysis showed that the left ventricular end-diastolic dimension z score (odds ratio (OR), 1.251; 95% confidence interval (CI), 1.004-1.559), extracorporeal membrane oxygenation (OR, 9.842; 95% CI, 1.044-92.764), and epinephrine infusion (OR, 18.552; 95% CI, 1.759-195.705) were significant predictors of mortality. The left ventricular end-diastolic dimension z score was the only factor that predicted incomplete recovery in the survivor group (OR, 1.360; 95% CI, 1.066-1.734; p=0.013). The receiver operating characteristic curve of the left ventricular end-diastolic dimension z score at admission showed a cut-off level of 3.01 for predicting mortality (95% CI, 0.714-0.948). In conclusion, a high left ventricular end-diastolic dimension z score on admission was a significant predictor of worse outcomes, both regarding mortality and incomplete recovery.

Abstract
We conducted a meta-analysis to provide the survival rates for pediatric patients hospitalized with fulminant myocarditis requiring ECMO. The literature search was conducted using Embase, PubMed, MEDLINE and Elsevier for studies published before April 1, 2016. We focus on survival rates for pediatric patients hospitalized with fulminant myocarditis requiring ECMO, and studies that reported only on adult patients were excluded. Summary of the survival rates was obtained using fixed-effect or random-effect meta-analysis which determined by I 2. Six studies were included in the analysis, encompassing 172 patients. The minimum and maximum reported rates of survival to hospital discharge were 53.8 and 83.3%, respectively. The cumulative rate was 107/172. The calculated Cochran Q value was 3.73, which was not significant for heterogeneity (P = 0.588). The I 2 value was 0%. The pooled estimate rate was 62.9% with a 95% confidence interval of 55.3-69.8%. In pediatric patients with cardiac failure who have failed conventional therapies in FM, venoarterial ECMO should be considered. In total, 62.9% of patients with FM and either cardiogenic shock and/or cardiac arrest survived to hospital discharge with ECMO.

Abstract
In children with fulminant myocarditis (FM), we sought to describe presenting characteristics and clinical outcomes, and identify risk factors for cardiac arrest and mechanical circulatory support (MCS). A retrospective review of patients with FM admitted at our institution between January 1, 2004, and June 31, 2015, was performed. We compared characteristics and outcomes of FM patients who received cardiopulmonary resuscitation (CPR) and/or were placed on MCS (CPR/MCS group) to those who did not develop these outcomes (Control group). There were 28 patients who met criteria for FM. Median age was 1.2 years (1 day-17 years). Recovery of myocardial function occurred in 13 patients (46%); 6 (21%) had chronic ventricular dysfunction, 6 (21%) underwent heart transplantation, and 3 (11%) died prior to hospital discharge (including one death following heart transplant). Of the 28 FM patients, 13 (46%) developed cardiac arrest (n = 11) and/or received MCS (n = 8). When compared to controls, patients in the CPR/MCS group had a higher peak b-type natriuretic peptide (BNP) levels (p = 0.03) and peak inotropic scores (p = 0.02). No significant differences were found between groups in demographics; chest radiograph, electrocardiogram, or echocardiogram findings; or initial laboratory values including BNP, troponin, C-reactive protein, lactate, and creatinine (p > 0.05 for all). Children with FM are at high risk of cardiovascular collapse leading to the use of CPR or MCS. Aside from peak BNP levels and inotropic scores, the most presenting characteristics were not helpful for predicting these outcomes. FM patients should ideally receive care in centers that provide emergent MCS.

Abstract
BACKGROUND Acute fulminant myocarditis (AFM) commonly presents as abrupt cardiogenic shock with or without dysrhythmia. This study evaluated the impact of extracorporeal membrane oxygenation (ECMO) on AFM-related hemodynamic compromise dysrhythmias. We also reported the clinical experience of AFM at our hospital. METHODS Eighteen children diagnosed with AFM were enrolled. Demographic variables, laboratory data, and clinical courses were reviewed. Thirteen surviving patients with hemodynamic compromise arrhythmia [complete atrioventricular block (CAVB) or ventricular tachycardia (VT)] during hospitalization were divided into Group A (ECMO group; n = 7) and Group B (non-ECMO group; n = 6). RESULTS The overall survival rate was 78% (14/18). There were no cases of mortality after ECMO was introduced at our hospital. Common symptoms at diagnosis included general malaise (94%), gastrointestinal symptoms (89%), chest pain (56%), shortness of breath (56%), and seizure/syncope (56%). In addition to abnormal cardiac enzyme levels, all patients displayed elevated alanine aminotransferase levels during early disease stages. Electrocardiography at diagnosis revealed dysrhythmia in 15 patients, namely, CAVB in 11 patients (61%) and VT in four patients (22%). During hospitalization, the dysrhythmia shifted from CAVB to VT in 10 patients and from sinus tachycardia to VT in one patient. New episodes of VT were common (overall occurrence rate, 83%). Although myocardial damage and dysfunction were more severe in Group A, the time to rhythm recovery in this group was shorter than that in Group B (median time, 1.7 days vs. 7.35 days, p = 0.045). All surviving patients had normal ventricular function at 6-month follow-up. CONCLUSION Hemodynamic compromise arrhythmia is common in AFM patients and may cause rapid deterioration. Simply correcting sinus rhythm is not always sufficient because of myocardium instability. Timely use of ECMO can improve the survival rate and shorten the time to recapture sinus rhythm in AFM patients with CAVB or VT.

Abstract
BACKGROUND This study aimed to discribe the experience in supporting children with refractory cardiopulmonary failure with extracorporeal membrane oxygenation (ECMO). METHODS We retrospectively reviewed 12 children with refractory cardiopulmonary failure supported with ECMO from February 2009 to August 2015 in the Pediatric Intensive Care Unit (PICU), Children's Hospital, Zhejiang University School of Medicine. RESULTS Seven of the 12 patients were weaned successfully from ECMO and dischaged from the hospital, with a survival rate of 58.3% (7/12). Among them, five patients had acute fulminant myocarditis (AFM). Complications during ECMO included hemorrhage, hemolysis, thrombosis, acute kidney injury, and secondary hematogenous infection. During 1-24 month follow-up, the seven surviving patients recovered with normal cardiopulmonary function. CONCLUSIONS ECMO is useful for supporting children with refractory cardiopulmonary failure, especially for treatment of AFM.
