Abstract
Infants are a unique transplant population due to a suspected immunologic advantage, in addition to differences in size and physiology. Consequently, we expect infants to have significantly different diagnoses, comorbidities, and outcomes than pediatric transplant recipients. In this study, we compare patterns and trends in pediatric and infant heart transplantation during three decades. The United Network for Organ Sharing (UNOS) database was queried for transplants occurring between January 1990 and December 2018. Patients were categorized as pediatric (1-17) or infant (0-1). Congenital heart disease (CHD) primary diagnoses have increased from 37% to 42% in pediatric patients (p = 0.001) and decreased from 80% to 61% in infants during the 1990s and 2010s (p < 0.001). Those with CHD had worse outcomes in both age groups (p < 0.001). Infants who underwent ABO-incompatible transplants had similar survival as compared to those with compatible transplants (p = 0.18). Overall, infants had better long-term survival and long-term graft survival than pediatric patients; however, they had worse short-term survival (p < 0.001). Death due to rejection or graft failure was less likely in infants (p = 0.034). However, death from infection was over twice as common (p < 0.001). In summary, pediatric and infant heart transplant recipients differ in diagnoses, comorbidities, and outcomes, necessitating different care for these populations.

Abstract
The purpose of this study was to gain a deeper understanding of maternal experiences of caring for their child with a VAD at home as a bridge to transplant. A descriptive, qualitative study was conducted via telephone-recorded guided interviews. Participants were caring for or had a child with a VAD between 4 and 16 years old. Data collection occurred over a 12-month period. Using the snowball sampling technique, a purposeful sample of mothers (n = 6) was consented and completed the interview. The data were analyzed using an iterative process of thematic analysis. Five themes emerged: physical modifications, the loss of independence, the emotional rollercoaster, support from others, and transitions on and off the device. We introduced new evidence about sleep, contraception, and heart transplantation, and how VAD therapy impacts childhood development. The mean duration of VAD support was 263 ± 170 days. Five children had heart transplants by the time of interview. To the best of our knowledge, this is the first qualitative study in the US that explores maternal experiences of caring for a child who is living at home with a VAD. VAD therapy is a novel approach to managing advanced heart failure among children and presents unique challenges when caring for them at home. Results provide insight into the education, physical environment, and support needed by parents.

Abstract
Pediatric patients are unique both in their diagnosis and clinical presentation before implantation of a ventricular assist device (VAD) and in their driveline site characteristics post-implant. There is limited evidence in scholarly literature that describes complications of pediatric VAD driveline sites or approaches by which to manage them. The Cardiac Center at The Children's Hospital of Philadelphia (CHOP) follows a standard of care for HeartWare VAD (HVAD) dressing changes in the inpatient setting with the goal of transitioning patients to weekly dressing changes by the time they are discharged to home. As a patient with an HVAD nears discharge, members of an interprofessional team collaborate with insurance providers and home care agencies to procure the appropriate supplies needed at home. Individualized plans of care are necessary for patients who are unable to transition to weekly dressings; however, customized products (such as silicone foam border dressings and antimicrobial agents) may be challenging to supply as single items from home care agencies. Between March 2014 and June 2017, 15 patients underwent HVAD implantation, and eight (53%) were discharged home. Ten patients (67%) were able to transition to weekly dressing changes. Individualized plans of care for driveline site management were required for six (40%) patients with persistent drainage. Three patients (20%) experienced a driveline site infection. This article describes how a quality improvement (QI) initiative using rapid-cycle improvement methodology was executed to standardize HVAD dressing changes in our pediatric population.

Abstract
The Cardiac Center at The Children's Hospital of Philadelphia has cared for patients with implanted ventricular assist device (VAD) technology since 1998. Historically, patients requiring VAD support were managed exclusively in the Cardiac Intensive Care Unit with the first medically stable transition to the Cardiac Care Unit (step-down) taking place in 2001. Patient management was confined to the inpatient setting, as the primary device used at the time was paracorporeal and not suitable for home use. Continuous-flow devices, such as the HeartWare HVAD, have gained popularity because of miniaturized size and lower profiles of side effects and adverse events, making them more suitable for home use. This article describes a single-center experience with transitioning the VAD-supported pediatric patient to the outpatient setting, highlighting outcomes, strategies, and lessons learned in order to support VAD patients and their caregivers in the hospital and community setting.

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
Here we report two cases of extracorporeal membrane oxygenation (ECMO) support in pediatric patients following orthotopic heart transplantation due to low cardiac output and inability to separate from cardiopulmonary bypass (CPB). Both patients had significant donor/recipient size mismatch: ratios were 0.71 and 1.73. Cannulation was via the right atrium to ascending aorta using Maquet ECMO kits to achieve veno-arterial ECMO (VA-ECMO) configuration. Activated clotting time (ACT) was maintained at 150-170 seconds. Systemic blood pressure goals were a mean arterial pressure of 60-80 mmHg. Both patients successfully recovered the cardiac function and were discharged home without severe complications. ECMO can effectively support pediatric patients after orthotopic heart transplantation to successful recovery despite the use of extreme donor/recipient size mismatch.

Abstract
Improvements in the care of children with cardiomyopathy, CHDs, and acquired heart disease have led to an increased number of children surviving with advanced heart failure. In addition, the advent of more durable mechanical circulatory support options in children has changed the outcome for many patients who otherwise would have succumbed while waiting for heart transplantation. As a result, more children with end-stage heart failure are being referred for heart transplantation, and there is increased demand for a limited donor organ supply. A review of important publications in the recent years related to paediatric heart failure, transplantation, and mechanical circulatory support show a trend towards pushing the limits of the current therapies to address the needs of this growing population. There have been a number of publications focussing on previously published risk factors perceived as barriers to successful heart transplantation, including elevated pulmonary vascular resistance, medication non-adherence, re-transplantation, transplantation of the failed Fontan patient, and transplantation in an infant or child bridged with mechanical circulatory support. This review will highlight some of these key articles from the last 3 years and describe recent advances in the understanding, diagnosis, and management of children with end-stage heart disease.

Abstract
Despite advances in medical and surgical therapies, some children with congenital heart disease (CHD) are not able to be adequately treated or palliated, leading them to develop progressive heart failure. As these patients progress to end-stage heart failure they pose a unique set of challenges. Heart transplant remains the standard of care; the donor pool, however, remains limited. Following the experience from the adult realm, the pediatric ventricular assist device (VAD) has emerged as a valid treatment option as a bridge to transplant. Due to the infrequent necessity and the uniqueness of each case, the pediatric VAD in the CHD population remains a topic with limited information. Given the experience in the adult realm, we were tasked with reviewing pediatric VADs and their use in patients with CHD and comparing this therapy to heart transplantation when possible.

Abstract
The pediatric ventricular assist device (VAD) has recently shown substantial improvements in survival as a bridge to heart transplant for patients with end-stage heart failure. Since that time, its use has become much more frequent. With increasing utilization, additional questions have arisen including patient selection, timing of VAD implantation and device selection. These challenges are amplified by the uniqueness of each patient, the recent abundance of literature surrounding VAD use as well as the technological advancements in the devices themselves. Ideal strategies for device placement must be sought, for not only improved patient care, but also for optimal resource utilization. Here, we review the most relevant literature to highlight some of the challenges facing the heart failure specialist, and any physician, who will care for a child with a VAD.

Abstract
PURPOSE OF REVIEW Ventricular assist devices (VADs) have revolutionized heart failure management in adults. Recently, VADs have similarly taken a prominent role in the management of end-stage heart failure in children. The purpose of this review is to describe the indications for VADs in children, types of devices available, current outcomes, and future directions of VAD therapy. RECENT FINDINGS There has been a dramatic increase in VAD utilization in children over the last decade. For small children, paracorporeal pneumatic pulsatile pumps (e.g., Berlin Heart EXCOR VAD, Berlin Heart GmbH, Berlin, Germany) are most commonly utilized for long-term support. In older children, intracorporeal continuous flow devices (e.g., HeartMate II Left Ventricular Assist System, Thoratec Corporation, Pleasanton, California, USA and HeartWare Ventricular Assist System, HeartWare Incorporated, Framingham, Massachusetts, USA) have been used and allow the possibility of destination therapy. Other devices, such as the total artificial heart, can be utilized for selected patients. Although overall outcomes of pediatric VADs are favorable, complication rates remain high. The utilization of VADs in complex circulations, such as single ventricle patients, remains infrequent and is associated with a high rate of adverse outcomes. SUMMARY VADs are well-established treatment for end-stage heart failure in children. Further investigation is needed to refine patient selection criteria, minimize complications, and develop additional pediatric-specific devices.

Abstract
Cardiomyopathies represent an uncommon but serious cause of heart disease in the pediatric population and can be categorized as dilated, hypertrophic, restrictive and left ventricular non-compaction. Each of these subtypes has multiple potential genetic etiologies in addition to possible non-genetic causes. Many patients with cardiomyopathies can benefit from transplantation, although there is not insignificant morbidity and mortality for those patients. Outcomes both prior to and following transplantation depend on the underlying etiology, the amount of support needed prior to transplantation and the illness severity of the patient prior to transplantation. Mechanical circulatory support is frequently used to bridge patients to transplantation, and newer technologies are currently in development.
