INTRODUCTION: Donor shortage and organ allocation is the main problem in pediatric heart transplant. Mechanical circulatory support is known to increase waiting list survival, but it is not routinely used in pediatric programs in Latin America. METHODS: All patients listed for heart transplant and supported by a mechanical circulatory support between January 2012 and March 2016 were included in this retrospective single-center study. The endpoints were mechanical circulatory support time, complications, heart transplant survival and discharge from the hospital...

Sudden cardiac death from ventricular arrhythmias is more common in adults with heart failure compared to pediatric heart failure patients. We identified age-specific differences in arrhythmogenesis using a guinea pig model of acute β-adrenergic stimulation. Young and adult guinea pigs were exposed to a β-adrenergic agonist, isoproterenol (ISO, 0.7mg/kg), for 30 minutes in the absence or presence of flecainide (20mg/kg), an antiarrhythmic that blocks sodium and ryanodine channels. Implanted cardiac monitors (Reveal LINQ{trade mark, serif}, Medtronic) were used to monitor heart rhythm...

Myocarditis is an inflammatory disease of the myocardium, leading to cardiac dysfunction and heart failure. Although viral infections are considered to be the most common etiology of myocarditis, identification of the causative virus is still challenging. Recently, next-generation sequencing (NGS) has been applied in the diagnosis of infectious diseases. The aim of the present study was to comprehensively analyze potential pathogenic microorganisms using NGS in sera of patients with myocarditis. Twelve pediatric and five adult patients hospitalized for acute myocarditis were included...

BACKGROUND: The treatment of acute lymphoblastic leukemia (ALL) and osteosarcoma (OSC) is very effective: the vast majority of patients recover and survive for decades. However, they still need to face serious adverse effects of chemotherapy. One of these is cardiotoxicity which may lead to progressive heart failure in the long term. Cardiotoxicity is contributed mainly to the use of anthracyclines and might have genetic risk factors. Our goal was to test the association between left ventricular function and genetic variations of candidate genes...

The purpose was to describe the incidence and risk factors of congestive heart failure (CHF) among children with acute lymphoblastic leukemia (ALL) and acute myeloid leukemia (AML). We included 2053 children (≤18 years) with first primary ALL and AML diagnosed 1992-2010 and registered in the Pediatric Oncology Group of Ontario Networked Information System. We identified CHF events through linked administrative databases. At 10 years, the cumulative incidence of CHF was 1.7% in ALL and 7.5% in AML. Factors associated with CHF in ALL were female gender, age <1 year at cancer diagnosis, irradiation and cumulative anthracycline dose ≥250 mg/m2 ...

The Berlin EXCOR ventricular assist device has become a standard treatment in pediatric bridge to transplantation. Despite its increased use in pediatric heart failure, the patient population supported with this technology continues to suffer from hematologic issues such as postoperative hemorrhage and neurologic dysfunction secondary to thrombotic events. Finding a balance between hemorrhagic and thrombotic risks in the acute postoperative period poses a significant challenge. In this report, we describe our approach using a temporary centrifugal pump connected to cannulas designed for the Berlin EXCOR ventricular assist device...

This study assesses the characteristics of coronary obstructions that underwent transcatheter intervention in a pediatric catheterization laboratory, the procedural details, and patient outcomes. Acute cardiac failure due to coronary obstructions in children is rare. The role of catheter based intervention is largely unreported. Single center retrospective review between January 2000 and December 2016. Thirty-three patients (median age 2y/o [0-38], weighing 9.6 kg [2.2-91]) underwent 39 transcatheter interventions on 39 lesions, mainly left main coronary (16/39; 39%) and right coronary (9/39; 23%) arteries...

BACKGROUND: Heart transplantation in infants and children is an accepted therapy for end-stage heart failure, but donor organ availability is low and always uncertain. Mechanical circulatory support is another standard option, but there is a lack of intracorporeal devices due to size and functional range. The purpose of this study was to evaluate the in vivo performance of our initial prototype of a pediatric continuous-flow total artificial heart (P-CFTAH), comprising a dual pump with one motor and one rotating assembly, supported by a hydrodynamic bearing...

IntroductionChildren with CHD and acquired heart disease have unique, high-risk physiology. They may have a higher risk of adverse tracheal-intubation-associated events, as compared with children with non-cardiac disease.Materials and methodsWe sought to evaluate the occurrence of adverse tracheal-intubation-associated events in children with cardiac disease compared to children with non-cardiac disease. A retrospective analysis of tracheal intubations from 38 international paediatric ICUs was performed using the National Emergency Airway Registry for Children (NEAR4KIDS) quality improvement registry...

BACKGROUND: Colchicine ingestion is rare but highly lethal. Patients usually die of multiorgan failure and cardiogenic shock. Colchicine is not only associated with depressed myocardial function but also with fatal heart rhythm disturbances, such as complete heart block, ventricular tachycardia, and asystole. While histologic changes of myocytes are well known, the mechanism by which colchicine affects cardiac impulse generation and conduction is not fully understood. CASE REPORT: We present a case of colchicine ingestion with sinus bradycardia, marked sinus arrhythmia, and first- and second-degree heart block...

Several previous reports have elucidated the mortality and incidence of complications after pediatric scoliosis surgery using nationwide databases. However, all of these studies were conducted in North America. Hence, this study aimed to identify the incidence and risk factors for in-hospital mortality and morbidity in pediatric scoliosis surgery, utilizing the Diagnosis Procedure Combination database, a national inpatient database in Japan.We retrospectively extracted data for patients aged less than 19 years who were admitted between 01 June 2010 and 31 March 2013 and underwent scoliosis surgery with fusion...

Background: Sepsis, trauma, and burn injury acutely depress systolic and diastolic cardiac function; data on long-term cardiac sequelae of pediatric critical illness are sparse. This study evaluated long-term systolic and diastolic function, myocardial fibrosis, and exercise tolerance in survivors of severe pediatric burn injury. Methods: Subjects at least 5 years after severe burn (post-burn:PB) and age-matched healthy controls (HC) underwent echocardiography to quantify systolic function (ejection fraction[EF%]), diastolic function (E/e'), and myocardial fibrosis (calibrated integrated backscatter) of the left ventricle...

Extracorporeal life support and heart and/or lung transplant are the last resort in children with end-stage cardiac and/or pulmonary failure and short-term life threaten. Currently, circulatory support is used as a bridge to recovery or as a bridge to transplant but not as a destination therapy. The Excor Berlin Heart is the long-lasting external pneumatic ventricular assist system that is currently available from infancy to adulthood. Long-term prognosis after pediatric cardiac and/or pulmonary transplant is conditioned by the occurrence of graft failure, coronary disease of the cardiac graft, viral infections and bronchiolitis obliterans of the pulmonary graft, the incidence of which increase with time...

REVIEW
Anne I Dipchand
Pediatric heart transplantation is standard of care for children with end-stage heart failure. The diverse age range, diagnoses, and practice variations continue to challenge the development of evidence-based practices and new technologies. Outcomes in the most recent era are excellent, especially with the more widespread use of ventricular assist devices (VADs). Waitlist mortality remains high and knowledge of risk factors for death while waiting and following transplantation contributes to decision-making around transplant candidacy and timing of listing...
