BACKGROUND: Kawasaki disease (KD) is known as systemic vasculitis, and more than half of the patients with KD have myocarditis, which can induce ventricular dysfunction. In this study, we evaluate left ventricular (LV) dysfunction in patients with KD based on the myocardial performance index (MPI) using pulse Doppler (PD) and tissue Doppler imaging (TDI), from the acute to convalescent phases. METHODS: We retrospectively studied 89 children diagnosed with KD from January 2010 to August 2012...

OBJECTIVE: Myocarditis is an important cause for cardiovascular morbidity and mortality in children and adults. The lncRNA taurine up-regulated gene 1 (TUG1) plays important roles in cell apoptosis and inflammation in tumor and liver injury. The present study aimed to investigate the role of TUG1 in LPS-injured H9c2 cells and explore the underlying molecular mechanism. METHODS: H9c2 cells were stimulated with LPS to induce inflammatory injury. The expression of TUG1 was altered by transient transfections...

Pediatric myocarditis is a common pediatric illness most commonly secondary to a preceding viral infection. It is a leading cause of acquired heart failure, cardiomyopathy, and cardiac transplantation in pediatrics. Due to the variability in presentation, the diagnosis is often unrecognized until later in the disease course. It should be considered in the differential diagnosis of all children presenting with respiratory distress, since this is the most common presentation. Imagining modalities, such as cardiac magnetic resonance imaging have become a useful diagnostic tool in recent years; however, endomyocardial biopsy remains the gold standard diagnostic test...

Myocarditis is an important but incompletely understood cause of cardiac dysfunction. Children with fulminant myocarditis often require inotropic or mechanical circulatory support, and researchers in some studies suggest that up to 42% of children who die suddenly have evidence of myocarditis. Recurrent myocarditis is extremely rare, and the vast majority of reported cases involve adult patients. Pediatric providers who suspect a recurrence of myocarditis have limited evidence to guide patient management because the literature in this domain is sparse...

BACKGROUND: Respiratory syncytial virus (RSV) infection is common and may be severe among patients with preexisting cardiac anomalies, but direct involvement of myocardial damage is not common in those patients. Additionally, myocardial involvement has been rarely described among immune compromised children. CASE PRESENTATION: A 4-year-old girl with acute lymphoblastic leukemia who received maintenance chemotherapy in an outpatient clinic developed systemic inflammatory response syndrome...

Objective: Demonstration of idiopathic dilated cardiomyopathy with unusual flow, unpredictable clinical picture and complex therapy. Case report: Patient A.P., female, 38 years old, had symptoms of dilated cardiomyopathy (with possible infectious myocarditis in the background) at age 17. After hospitalization for ten months and ten days, while waiting for heart transplantation (with threatening death outcome), without a clearly pronounced threatening arrhythmia, but with a low ejection fraction and a poor general condition, remission occurred...

The pediatric cardiology field has developed rapidly over the past few decades. More children than ever born with congenital heart disease (CHD) are growing into adulthood. Primary care providers play a key role in diagnosis, management, and referral of children with CHD because many common cardiac complaints (eg, feeding intolerance, cyanosis, chest pain, palpitations, and syncope) are first addressed in the primary care setting. The spectrum of heart disease in children ranges from common complaints to complex single-ventricle physiology, acute myocarditis, and heart transplantation...

INTRODUCTION: Hepatitis A virus (HAV) causes an acute infection and is usually asymptomatic in children. When clinical manifestations appear, these include choluria, jaundice, and abdominal pain. Although infrequent, extra-hepatic manifestations related to HAV have been described affecting the heart, bone marrow, blood vessels, and others. CASE: A 10-year-old boy from a rural area presented with a 15-day history of malaise, fever, and jaundice; laboratory exams were compatible with HAV Infection...

Human enteroviruses (EVs) are the most common causative agents infecting human, causing many harmful diseases, such as hand, foot, and mouth disease (HFMD), herpangina (HA), myocarditis, encephalitis, and aseptic meningitis. EV-related diseases pose a serious worldwide threat to public health. To gain comprehensive insight into the seroepidemiology of major prevalent EVs in humans, we firstly performed a serological survey for neutralizing antibodies (nAbs) against Enterovirus A71 (EV-A71), Coxsackie virus A16 (CV-A16), Coxsackie virus A6 (CV-A6), Coxsackie virus A10 (CV-A10), Coxsackie virus B3 (CV-B3), Coxsackie virus B5 (CV-B5), Echovirus 25 (ECHO25), and Echovirus 30 (ECHO30) among the healthy population in Xiamen City in 2016, using micro-neutralization assay...

Fulminant myocarditis (FM) is a life-threatening disease in children. With a rapid, progressive course of deterioration, it causes refractory cardiorespiratory failure even with optimal clinical intervention. We present the case of a 9-year-old girl with FM complicated by cardiogenic shock, malignant arrhythmia, and refractory cardiac arrest. She received effective cardiopulmonary resuscitation, therapeutic hypothermia, and other supportive treatments. However, the patient rapidly worsened into pulseless ventricular tachycardia and refractory cardiac arrest...

BACKGROUND: Historically, the "temporary" or short-term ventricular assist device (VAD) was used only as a quick bridge to recovery for children with an acute process. In the current era, the devices that were originally used for temporary support are now being used to support children for longer durations and for a variety of indications. In this study we aimed to describe the overall use, patients' characteristics and outcomes of "temporary" VAD use in children. METHODS: The Pediatric Interagency Registry for Mechanical Circulatory Support (PediMACS) is a National Institutes of Health-supported national registry for United States Food and Drug Administration-approved VADs in patients <19 years of age at the time of VAD implantation (either durable or temporary VAD)...

Coxsackievirus A16 (CA16), which primarily causes hand, foot, and mouth disease (HFMD), is associated with complications, such as encephalitis, acute flaccid paralysis, myocarditis, pericarditis, and shock. However, no case of pancreatitis associated with CA16 has been reported in children. We report a case of CA16-associated acute pancreatitis in a 3-year-old girl with HFMD. She was admitted because of poor oral intake and high fever for 1 day. Maculopapular rashes on both hands and feet and multiple vesicles on the soft palate were observed on physical examination...

BACKGROUND: Epidemiology of myocarditis in childhood is largely unknown. Men are known to have a higher incidence of myocarditis than women in adults aged <50 years, but whether this is true by sex in pediatric age groups is unknown. We set out to study the occurrence and potential sex differences of myocarditis in a general pediatric population. METHODS AND RESULTS: Data of all hospital admissions with myocarditis in Finland occurring in patients aged ≤15 years from 2004 to 2014 were collected from a mandatory nationwide registry...

Kawasaki disease (KD) is the most common vasculitis of childhood. Coronary artery aneurysms and myocarditis are common cardiovascular complications of KD. While evidence of myocarditis can be found in all patients with KD on histology specimens, only a minority of patients are clinically symptomatic. Occasionally children can present with KD shock syndrome and hemodynamic instability as a result of decreased systolic function and vasoplegia. Several children with KD have depressed shortening fraction on echocardiography...
