Studies in adult HT have demonstrated improved cardiac function in the recipient following administration of T3 to the donor. The purpose of this experiment was to assess the effects of T3 on the function of the immature donor heart following HT in a piglet model. A total of 32 piglets were divided into 16 donors and 16 recipients. Following creation of brain death, half of the donor piglets were randomized to receive three doses of T3 (0.2 μg/kg) along with hydrocortisone (1 mg/kg). The donor hearts were then transplanted into the recipient piglets on CPB...

Murray H Kwon, Richard J Shemin
Tricuspid valve regurgitation (TVR) in the orthotopic heart transplant (OHT) recipient is quite common and has varied clinical sequelae. In its severest forms, it can lead to right-sided failure symptoms indistinguishable from that seen in native heart TVR disease. While certain implantation techniques are widely recognized to reduce the risk of TVR in the cardiac allograft, concomitant tricuspid annuloplasty, while having advocates, is not currently accepted as a routinely established adjunct. Decisions to surgically correct TVR in the OHT recipient must be made carefully, as certain clinical scenarios have high risk of failure...

BACKGROUND: Isolated tricuspid valve (ITV) operations are infrequent and the decision to operate is controversial. We report a series of ITV operations to outline the current disease status requiring this uncommon procedure with an emphasis on the results of tricuspid valve repair (TVr) versus replacement (TVR). METHODS: Using our prospective cardiac surgery database, 57 patients who underwent ITV operations between 01/02-03/14 were identified. Median follow up time was 3...

Cardiovascular disease (CVD) complications are important causes of morbidity and mortality after orthotopic liver transplantation (OLT). There is currently no preoperative risk assessment tool that allows physicians to estimate the risk for CVD events following OLT. We sought to develop a point-based prediction model (risk score) for CVD complications after OLT, the CAR-OLT risk score, among a cohort of 1024 consecutive patients aged 18-75 years who underwent first OLT in a tertiary-care teaching hospital (2002-2011)...

BACKGROUND: Cardiac allograft vasculopathy (CAV) affects approximately 30% of cardiac transplant patients at five years post-transplantation. To date there are few CAV treatment or prevention options, none of which are highly effective. The aim of the study was to investigate the effect of thalidomide on the development of CAV. METHODS: The effect of thalidomide treatment on chronic rejection was assessed in rat orthotopic aortic transplants in allogeneic F344 or syngeneic Lew rats (n=6/group)...

Invasive aspergillosis generally occurs during the first 1-6 months after heart transplantation. It has been rarely seen in the first 2 weeks postcardiac transplant. We herein describe a unique case of invasive pulmonary aspergillosis (IPA) diagnosed on day 9 postorthotopic heart transplantation. The known risk factors for IPA in cardiac transplant recipients were not identified in our case. The organ recipients from the same donor did not report Aspergillus infection. Hospital environmental samplings failed to demonstrate Aspergillus spores in the patient's room and his adjacent rooms...

BACKGROUND: Non-surgical bleeding (NSB) due to angiodysplasia is common in left ventricular assist device (LVAD) patients. Thrombin-induced angiopoietin-2 (Ang-2) expression in LVAD patients leads to altered angiogenesis and is associated with lower angiopoietin-1 (Ang-1) and increased NSB. However, the mechanism for decreased Ang-1, made by pericytes, is unknown and the origin of thrombin in LVAD patients is unclear. We hypothesized that high tumor necrosis factor-α (TNF-α) levels in LVAD patients induce pericyte apoptosis, tissue factor (TF) expression and vascular instability...

According to the Centers for Disease Control (CDC), heart failure (HF) remains a pervasive condition with high morbidity and mortality, affecting 5.8 million people in the United States (US) and 23 million worldwide. For patients with refractory end-stage HF, heart transplantation is the gold standard for definitive treatment. However, the demand for heart transplantation has consistently exceeded the availability of donor hearts, with approximately 2,331 orthotopic heart transplantations performed in the US in 2015 despite an estimated 100,000 to 250,000 patients with New York Heart Association (NYHA) class IIIB or IV symptoms that are refractory to medical treatment and potential transplant candidates...

BACKGROUND: Until recently, transplantation from hepatitis C positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen which has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature but little is known about the safety and efficacy of treatment in heart transplantation...

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)...

A patient with history of orthotopic heart transplant (OHT) followed by tricuspid valve replacement and two subsequent balloon valvuloplasties was offered transcatheter tricuspid valve replacement (TTVR) to avoid what would have been his fourth sternotomy. TTVR in patients with OHT can be a valuable approach to prevent further open-heart surgeries, which carry added morbidity and mortality.

INTRODUCTION: This retrospective study examined the role of aortic valve (AV) disease in patients who underwent orthotopic liver transplantation (OLT) to determine the incidence of postoperative cardiac morbidity and mortality when compared with a matched control group without AV disease. METHODS: Patients were included in the AV group if diagnosed with aortic stenosis (AS) or aortic regurgitation or had received AV replacement prior to OLT. The AV group (n = 53) was matched to a control group (n = 212) with the following preoperative variables: type of organ transplanted, age, gender, race, body mass index, MELD, redo-transplantation, preoperative renal replacement therapy, nonalcoholic steatohepatitis, viral hepatitis, diabetes, and coronary artery disease...

BACKGROUND: Orthotopic heart transplantation (OHT) is the gold-standard therapy for end-stage heart failure. An increasing deficit between suitable allograft availability and clinical demand for OHT exists. The role of donor diabetes mellitus (DM) on post-transplant recipient outcomes in OHT is controversial. The purpose of this study was to examine donor hemoglobin A1c (HbA1c) levels to identify the impact of donor glycemic control on recipient survival. METHODS: Adult OHT recipients with donor HbA1c data were identified in the UNOS database from 2010 to 2015...

BACKGROUND Calcineurin inhibitor-induced posterior reversible encephalopathy syndrome (PRES) is well described in liver and kidney transplant patients, but there is a paucity of data in heart transplant patients. PRES syndrome in the setting of heart transplantation can occur as early as 5 days following transplantation. CASE REPORT A 32-year-old woman who had recently undergone orthotopic heart transplantation developed headaches, visual disturbances, and generalized tonic clonic seizures 5 days after initiating anti-rejection therapy (tacrolimus, mycophenolate, and prednisone)...

BACKGROUND: There is inadequate power to perform a valid clinical trial in pediatric heart transplantation (HT) using a conventional end-point, because the disease is rare and hard end-points, such as death or graft loss, are infrequent. We sought to develop and validate a surrogate end-point involving the cumulative burden of post-transplant complications to predict death/graft loss to power a randomized clinical trial of maintenance immunosuppression in pediatric HT. METHODS: Pediatric Heart Transplant Study (PHTS) data were used to identify all children who underwent an isolated orthotopic HT between 2005 and 2014 who survived to 6 months post-HT...

Current criteria for donor hearts limit the number of hearts available for transplantation, despite an increasing number of recipients on waiting lists. We report the case of a patient with ischemic cardiomyopathy and refractory ventricular tachycardia who underwent successful orthotopic heart transplantation and concurrent aortic valve replacement with a donor heart that had displayed moderate aortic valve regurgitation. The patient was a 71-year-old man with a history of advanced heart failure, 5-vessel coronary artery bypass grafting, and paroxysmal ventricular tachycardia...
