BACKGROUND: Exercise-based cardiac rehabilitation (CR) is under-utilized. CR is indicated after heart transplantation, but there are no data regarding CR participation in transplant recipients. We characterized current CR utilization among heart transplant recipients in the United States and the association of CR with 1-year readmissions using the 2013-2014 Medicare files. METHODS: The study population included Medicare beneficiaries enrolled due to disability (patients on the transplant list are eligible for disability benefits under Medicare regulations) or age ≥65 years...

BACKGROUND: Use of new genomic techniques in clinical settings requires that such methods are rigorous and reproducible. Previous studies have shown that quantitation of donor-derived cell-free DNA (%ddcfDNA) by unbiased shotgun sequencing is a sensitive, non-invasive marker of acute rejection after heart transplantation. The primary goal of this study was to assess the reproducibility of %ddcfDNA measurements across technical replicates, manual vs automated platforms, and rejection phenotypes in distinct patient cohorts...

BACKGROUND: Stroke is the most feared complication associated with the Berlin Heart EXCOR pediatric ventricular assist device (VAD), the most commonly used VAD in children, and affects 1 in 3 children. We sought to determine whether a modified anti-thrombotic guideline, involving more intense platelet inhibition and less reliance on platelet function testing, is associated with a lower incidence of stroke. METHODS: All children supported with the EXCOR at Stanford from 2009 to 2014 were divided into 2 cohorts based on the primary anti-thrombotic guideline used to prevent pump thrombosis: (1) the Edmonton Anti-thrombotic Guideline (EG) cohort, which included children implanted before September 2012 when dual anti-platelet therapy was used with doses titrated to Thromboelastrography/PlateletMapping (TEG/PM); and (2) the Stanford Modified Anti-thrombotic Guideline (SG) cohort, which included children implanted on or after September 2012 when triple anti-platelet therapy was used routinely and where doses were uptitrated to high, weight-based dosing targets, with low-dose steroids administered as needed for inflammation...

BACKGROUND: Ex vivo lung perfusion (EVLP) has improved the process of donor lung management. Cytokine accumulation during EVLP has been shown to correlate with worse outcome after lung transplantation. Our objective in this study was to test the safety and efficacy of cytokine filtration during EVLP in a large animal model. METHODS: Pig donor lungs were preserved for 24 hours at 4°C, followed by 12 hours of EVLP, according to the Toronto protocol. The perfusate was continuously run through an absorbent device (CytoSorb) via a veno-venous shunt from the reservoir in the filter group...

BACKGROUND: There is growing concern regarding the association between pre-transplant amiodarone exposure and post-transplant adverse outcomes. We hypothesized that amiodarone use would be associated with the development of severe primary graft dysfunction (PGD) in a dose-dependent manner. METHODS: This was a retrospective review of 269 adult orthotopic heart transplantation (OHT) recipients at our institution between 2010 and 2014. At the time of OHT, 100 were receiving amiodarone therapy (Group 1) and 169 were not (Group 2)...

BACKGROUND: The presence of pre-formed IgA anti-β2-glycoprotein I antibodies (IgA-aB2GP1ab) has been related to early graft loss after kidney transplant. Because β2-glycoprotein I is produced in both the kidney and heart, we aimed to assess whether the presence of these antibodies may also be associated with poor outcomes after heart transplantation (HT). METHODS: A 2-year follow-up retrospective analysis of 151 consecutive patients who underwent HT between 2004 and 2012 was performed to assess the role of this pre-formed antibody type in HT...

BACKGROUND: Extended criteria donor lungs deemed unsuitable for immediate transplantation can be reconditioned using ex vivo lung perfusion (EVLP). Objective identification of which donor lungs can be successfully reconditioned and will function well post-operatively has not been established. This study assessed the predictive value of markers of inflammation and tissue injury in donor lungs undergoing EVLP as part of the DEVELOP-UK study. METHODS: Longitudinal samples of perfusate, bronchoalveolar lavage, and tissue from 42 human donor lungs undergoing clinical EVLP assessments were analyzed for markers of inflammation and tissue injury...

BACKGROUND: Induction therapy is increasingly being used in pediatric heart transplantation. General versus risk-adapted use remains controversial. We aimed to determine the impact of induction therapy on outcomes after stratifying patients by diagnosis and risk. METHODS: The Pediatric Heart Transplant Study (PHTS) database was used to identify patients (age ≤18 years) who underwent transplantation between January 1, 2001 and December 31, 2014. Patients were excluded if they survived <48 hours or received multiple induction agents...

BACKGROUND: Bacterial infections represent a major cause of morbidity and mortality in heart transplant recipients. However, data describing the epidemiology and outcomes of these infections in children are limited. METHODS: We analyzed the Pediatric Heart Transplant Study database of patients transplanted between 1993 and 2014 to determine the etiologies, risk factors and outcomes of children with bacterial infections post-heart transplantation. RESULTS: Of 4,458 primary transplants in the database, there were 4,815 infections that required hospitalization or intravenous therapy, 2,047 (42...

Over the past decade, continuous-flow rotary pumps have dramatically improved survival for patients with advanced systolic heart failure. Bleeding and thrombosis, however, continue to be the Achilles heel of left ventricular assist device (LVAD) therapy. There is a dynamic and complex interaction between the patient and pump. The net effect of a variety of hematologic derangements, such as hemolysis, high-molecular-weight von Willebrand degradation, platelet activation and diminished pulsatility, is poorly understood...

BACKGROUND: Primary graft dysfunction (PGD) is a major cause of early morbidity and mortality after lung transplantation. Statins reduce the risk of chronic rejection after lung transplantation, but their effects on PGD are unknown. We hypothesized that perioperative statin therapy decreases the risk for PGD after lung transplantation. METHODS: We retrospectively reviewed records of all patients undergoing lung transplantation between January 1999 and December 2014 at the University of Virginia Health System...

BACKGROUND: Since 1996, ABO-incompatible heart transplantation has been undertaken by performing whole-body plasma exchange to remove isohemagglutinins using the cardiopulmonary bypass (CPB) circuit at the time of transplantation. This requires large volumes of donated blood and blood products, causes hemodynamic instability during the exchange transfusion, and limits practical use to small children. We sought to determine the efficacy of anti-A/B immunoadsorption within the CPB circuit on removal of isohemagglutinins in an ex vivo setting before its use clinically...
