Heart transplantation in children with intellectual disability (ID) is an issue of debate due to the shortage of available donor organs. We sought to perform the first large-scale retrospective cohort study describing the prevalence and outcomes of heart transplantation in this population. The United Network of Organ Sharing database was queried from 2008 to 2015 for pediatric patients (age <19 years) receiving first, isolated heart transplant. Recipients were divided into three subgroups: definite ID, probable ID, and no ID...

Significant racial disparity remains in the incidence of unfavorable outcomes following heart transplantation. We sought to determine which pediatric post-transplantation outcomes differ by race and whether these can be explained by recipient demographic, clinical, and genetic attributes. Data were collected for 80 black and 450 non-black pediatric recipients transplanted at 1 of 6 centers between 1993 and 2008. Genotyping was performed for 20 candidate genes. Average follow-up was 6.25 years. Unadjusted five-year rates for death (p=0...

In pediatric heart transplantation, the size of the donor organ is an important criterion for organ allocation. Oversized donor hearts are often accepted with good results, but some complications in relation to a high donor-recipient ratio have been described. Our patient was transplanted for progressive heart failure in dilated cardiomyopathy. The donor-to-recipient weight ratio was 3 (donor weight 65 kg, recipient weight 22 kg). The intra-operative echocardiography before chest closure showed excellent cardiac function, no tricuspid valve regurgitation, and a normal central venous pressure...

We experienced a case of ventricular assist with both a pulsatile-flow and a continuous-flow pump in a pediatric patient, and herein report the clinical course and characteristics of the pumps. A 6-year-old female was diagnosed with fulminant myocarditis and transferred to our hospital for mechanical support. After 12 days of extracorporeal membrane oxygenation, we implanted a left ventricular assist device (LVAD) and a right ventricular assist device (RVAD) using centrifugal Gyro pumps with a membrane oxygenator in a paracorporeal fashion...

Pericardial effusion (PE) may require readmission after cardiac surgery and has been associated with postoperative morbidity and mortality. We sought to identify the prevalence and risk factors for postoperative PE requiring readmission in children. A retrospective analysis of the Pediatric Health Information System database was performed between January 1, 2003, and September 30, 2014. All patients ≤18 years old who underwent cardiac surgery were identified by ICD-9 codes. Those readmitted within 1 year with an ICD-9 code for PE were identified...

We report the patterns of rehospitalization after pediatric heart transplant (Htx) at a single center. Retrospective review of 107 consecutive pediatric Htx recipients between January 22, 2007, and August 28, 2014, who survived their initial transplant hospitalization. The frequency, duration, and indications for all hospitalizations between transplant hospitalization discharge and September 30, 2015, were analyzed. A total of 444 hospitalization episodes occurred in 90 of 107 (84%) patients. The median time to first rehospitalization was 59...

BACKGROUND: United Network for Organ Sharing (UNOS) policy enables listing exceptions to avoid penalizing patients with waitlist mortality not captured by standard criteria. Outcomes among patients listed by exception have not been analyzed. METHODS: We performed a retrospective analysis of pediatric (≤17 years of age, n = 4,706) listings (2006 to 2015) for primary, isolated heart transplantation within the UNOS data set, assessing Status 1A exception (n = 211, 4...

Transplant center expertise improves survival after heart transplant (HTx) but it is unknown whether center expertise ameliorates risk associated with mechanical circulatory support (MCS) bridge to transplantation. This study investigated whether center HTx volume reduced survival disparities among pediatric HTx patients bridged with extracorporeal membrane oxygenation (ECMO), left ventricular assist device (LVAD), or no MCS. Patients ≤18 years of age receiving first-time HTx between 2005 and 2015 were identified in the United Network of Organ Sharing registry...

Endomyocardial biopsy (EMB) with fluoroscopy is used for rejection surveillance in pediatric heart transplantation. Lowering frame rate may reduce radiation, but decreases temporal resolution and image quality. We undertook a quality initiative reducing frame rate from 10 frames per second (FPS) to 5 FPS. To assess whether lowering frame rate can reduce radiation exposure without compromising safety, data on EMBs from 9/2009 to 4/2013 without angiography or intervention were reviewed. Effective dose was calculated from dose area product (DAP) and fluoroscopy time...

BACKGROUND: Cardiac allograft vasculopathy (CAV) is a crucial problem after heart transplantation, in adults as well as in children. CAV is the main risk factor for a reduced long-term graft survival. The early diagnosis and treatment of CAV is essential for a successful long-term preservation of the donor heart. However, asymptomatic progression of CAV and concentric hyperplasia of the coronary arteries may complicate the early diagnosis by conventional measures. Intravascular imaging, such as intravascular ultrasound and optical coherence tomography (OCT), enables the diagnosis of early stage CAV...

BACKGROUND: The effect of age at transplant on rejection detected by routine surveillance biopsy (RSB) in pediatric heart transplant (HT) recipients is unknown. We hypothesized there would be low diagnostic yield and decreased prevalence of rejection detected on RSB in infants (age <1 year) when compared with children (age 1 to 9 years) and adolescents (age 10 to 18 years). METHODS: We utilized Pediatric Heart Transplant Study (PHTS) data from 2010 to 2013 to analyze moderate-to-severe (ISHLT Grade 2R/3R) cellular rejection (MSR) detected only on RSB (RSBMSR)...

BACKGROUND: Cardiac allograft vasculopathy (CAV) is the leading cause of chronic allograft loss after pediatric heart transplantation. We hypothesized that biomarkers of endothelial injury and repair would predict CAV development in pediatric heart transplant recipients. METHODS: Blood was collected from pediatric heart transplant recipients at the time of routine annual coronary angiography, and the concentrations of 13 angiogenesis-related molecules were determined...

BACKGROUND: Less than 2.7% of infants undergoing congenital heart disease operations have difficulty weaning from invasive mechanical ventilation. In such instances, clinicians may choose to perform tracheostomy. Limited literature has examined tracheostomy placement specifically in infants with hypoplastic left heart syndrome (HLHS). This study evaluated the risk factors for tracheostomy placement in infants with HLHS and examined the outcomes of these infants before their first hospital discharge...

In adults on chronic hemodialysis, achieving a hemoglobin concentration of 12g/dl and above with erythropoiesis stimulating agents leads to increased cardiovascular events and mortality, but this may not be true in children. Therefore, we conducted a retrospective cohort study of pediatric patients (under 18) from the Centers for Medicare and Medicaid Services End Stage Renal Disease (ESRD) Clinical Performance Measures (CPM) project (2000 to 2008) merged with the United States Renal Data System. Hemoglobin was determined from the Clinical Performance Measures data, and beginning annually on January 1st of the next year, patients were followed for up to 1 year...

BACKGROUND: Historically, patients with a prior Fontan procedure for complex congenital heart disease (CHD) have been considered at higher risk for death after heart transplant (HT) compared with other HT transplant candidates. With the overall trend of improved survival of pediatric HT recipients, it is unclear of Fontan patient post-HT survival has also improved in the current era. METHODS: Data from the Pediatric Heart Transplant Study database for Fontan patients who underwent HT was compared between the early era (1993 to 2006, n = 150) and late era (2007 to 2014, n = 252)...

Despite substantial improvements in survival after pediatric heart transplantation, refractory rejection remains a major cause of morbidity and mortality. We have utilized ALE (Campath-1H) in six consecutive patients with refractory rejection. These rejection episodes persisted despite conventional treatment, which included intravenous methylprednisolone, rituximab, immunoglobulin G, and antithymocyte globulin. In our series, after ALE therapy, LV SF increased from 22%±5% to 33%±5% (P=.01). However, in our series, ALE therapy neither led to persistent LV function recovery nor could it prevent subsequent antibody-mediated rejection...

Lung disease in children often results in pulmonary hypertension and right heart failure. The availability of a pediatric artificial lung (PAL) would open new approaches to the management of these conditions by bridging to recovery in acute disease or transplantation in chronic disease. This study investigates the efficacy of a novel PAL in alleviating an animal model of pulmonary hypertension and increased right ventricle afterload.Five juvenile lambs (20-30 Kg) underwent PAL implantation in a pulmonary artery to left atrium configuration...

The use of mechanical circulatory support (MCS) devices is a viable therapeutic treatment option for patients with congestive heart failure. Ventricular assist devices, cavopulmonary assist devices, and total artificial heart pumps continue to gain acceptance as viable treatment strategies for both adults and pediatric patients as bridge-to-transplant, bridge-to-recovery, and longer-term circulatory support alternatives. We present a review of the current and future MCS devices for patients having congenital heart disease (CHD) with biventricular or univentricular circulations...

Congenital heart disease accounts for 40% of pediatric heart transplants and presents unique challenges to the transplant team. Suitability for transplantation is defined in part by degree of sensitization, pulmonary vascular resistance, and hepatic reserves. The incremental transplant risk for patients with congenital heart disease occurs within the first 3 months, after which survival is equivalent to transplantation for cardiomyopathy. Single ventricle with prior palliation, and especially the failing Fontan, carry the highest risk for transplantation and are least amenable to bridging with mechanical circulatory support...
