AIMS: Heart transplantation (HTx) has become the standard treatment for patients with end-stage heart disease. We report on the long-term outcome after HTx at our centre and investigate trends in outcome over time. METHODS: During the period, between 1984 and 2014, a total of 610 HTx procedures were performed in 595 patients (median 48years; IQR 31-57years; range 24days-71years; mean 43years; 75% male) in our institution. Long-term outcome was investigated in the whole cohort, among children (n=76), bridged with mechanical circulatory support (MCS, n=131), re-transplanted (n=17), and concomitant kidney transplantation (n=12)...

Left ventricular noncompaction (LVNC) may result in systolic left ventricular (LV) failure resulting in the need for heart transplantation. LV assist devices (LVAD) have been used to bridge these patients to transplantation; however, the extensive trabeculations found in these patients predispose them to thromboembolic events and pump thrombosis. We describe a patient with LVNC in whom an aggressive surgical approach was used to debride the LV cavity of trabeculations to successfully implant an LVAD.

Patients listed for organ transplant frequently have severe coronary artery disease (CAD), which may be treated with drug eluting stents (DES). Everolimus and zotarolimus eluting stents are commonly used. Newer generation biolimus and novolimus eluting biodegradable stents are becoming increasingly popular. Patients undergoing transplant surgery soon after the placement of DES are at increased risk of stent thrombosis (ST) in the perioperative period. Dual antiplatelet therapy (DAPT) with aspirin and a P2Y12 inhibitor such as clopidogrel, prasugrel and ticagrelor is instated post stenting to decrease the incident of ST...

Despite the spontaneous regenerative capacity of the peripheral nervous system, large gap peripheral nerve injuries (PNIs) require bridging strategies. The limitations and suboptimal results obtained with autografts or hollow nerve conduits in the clinic urge the need for alternative treatments. Recently, we have described promising neuroregenerative capacities of Schwann cells derived from differentiated human dental pulp stem cells (d-hDPSCs) in vitro. Here, we extended the in vitro assays to show the pro-angiogenic effects of d-hDPSCs, such as enhanced endothelial cell proliferation, migration and differentiation...

BACKGROUND: The role of implantable cardioverter defibrillator (ICD) in reducing mortality in patients with left ventricular assisted devices (LVADs) listed for heart transplant remains unclear. We therefore, sought to interrogate whether ICDs are associated with reduced mortality in patients with LVADs listed for heart transplantation. METHODS: We searched the United Network for Organ Sharing (UNOS) Registry for LVAD patients (age≥18years) with dilated cardiomyopathies listed for heart transplantation (2008-2015)...

The use of continuous-flow left ventricular assist devices (CF-LVADs) has revolutionized the landscape of mechanical circulatory support for patients with heart failure. Clinical trials are already testing the next generation of CF-LVADs. In this study, our objective was to review our long-term experience with the current generation of CF-LVADs, specifically, the HeartMate (HM) II (Thoratec Corp, Pleasanton, CA). In this single-center retrospective analysis, we evaluated the records of 278 consecutive patients who underwent a total of 302 HM II placements from June 2005 through June 2014...

A 13-year obese female with suspected viral myocarditis presented with acute decompensated heart failure. Due to her body habitus, she was a poor candidate for immediate heart transplantation. A peripherally inserted left ventricular assist device (LVAD) was implanted via the right axillary artery. Following device insertion the patient experienced rapid improvement in symptoms. The LVAD provided effective left ventricular unloading for 50 days, promoting myocardial recovery and maintaining excellent patient performance status...

Globalization has resulted in epidemiologic transition in developing countries from infectious disease and nutritional deficiencies to non-communicable diseases. Epidemiologic data on heart failure (HF), particularly advanced HF therapy, in Asia are increasingly becoming available, although they remain sparse. Heart transplantation for advanced stage HF remains very low in Asia-approximately 0.075 heart transplants per 1 million population. North America, which comprises 7.5% of the world population, accounted for 55...

Recent advances in antibody technology to harness T-cells for cancer immunotherapy, particularly in the difficult-to-treat setting of relapsed or refractory acute lymphoblastic leukemia (r/r ALL), has led to innovative methods for directing cytotoxic T-cells to specific surface antigens on cancer cells. One approach involves administration of soluble bispecific (or dual-affinity) antibody-based constructs that temporarily bridge T-cells and cancer cells. Another approach infuses ex vivo-engineered T-cells that express a surface plasma membrane-inserted antibody construct called a chimeric antigen receptor (CAR)...

A continuous-flow left ventricular assist device (CF-LVAD) benefits patients with advanced heart failure as a bridge to cardiac transplantation. However, unanticipated complications may occur. We report a patient with end-stage heart failure and longstanding diabetes who experienced functionally debilitating orthostatic hypotension from autonomic insufficiency after CF-LVAD implantation. This case demonstrates a role for comprehensive autonomic function testing in the workup of orthostatic hypotension after LVAD implantation...

Outcome of patients with primary refractory/relapsed (R/R) acute myeloid leukemia (AML) remains dismal. Herein, we present a retrospective monocentric study of 24 very high-risk AML patients who received a combination of fractionated gemtuzumab ozogamicin (GO) with intermediate-dose cytarabine and daunorubicin as salvage therapy. Median age was 55.3 years. Diagnostic was secondary AML for 33% of them. Seven patients had favorable risk, 8 had intermediate-1 or intermediate-2, and 6 had unfavorable risk of AML according to the European LeukemiaNet prognostic index...

The duration of support in patients with HeartMate II implantation as a bridge to transplant or as destination therapy is rising. As clinical experience continues to grow, physiologic changes contributing to pump malfunction are becoming apparent. Once malfunction is noted with increased power spikes, rises in lactate dehydrogenase and low-flow alarms, thrombosis of the pump is at risk. We describe outflow graft compression and offer an expeditious and definitive management strategy. Our novel management stenting strategy for outflow graft compression will continue to evolve as experience is gained...

Schwann cell (SC) transplantation is an attractive strategy for spinal cord injury (SCI). However, the efficacy of SC transplantation has been limited by the poor migratory ability of SCs in the astrocyte-rich central nervous system (CNS) environment and the inability to intermingle with the host astrocyte. In this study, we first magnetofected SCs by polysialyltransferase-functionalized superparamagnetic iron oxide nanoparticles (PST/SPIONs) to induce overexpression of polysialylation of neural cell adhesion molecule (PSA-NCAM) to enhance SC migration ability, before manipulating the direction of SC migration with the assistance of an applied magnetic field (MF)...

Objective: Despite the improvement in ventricular assist device (VAD) therapy in adults and in adolescents, in infant population only Berlin Heart EXCOR (BHE) is licensed as long term VAD to bridge children to Heart Transplantation (HTx). Particularly demanding in terms of morbidity and mortality are smallest patients namely the ones implanted in the first year of life or with a lower body surface area. This work aims at retrospective reviewing a single center experience in using BHE in children with a body weight under 10 kg...

BACKGROUND: The role of hepatic hemodynamic modulation in the development of "small-for-size" syndrome (SFSS) after extended hepatectomy (EH) or living-donor liver transplantation is still controversial. We have designed an experimental study to investigate the effect of hemodynamic parameters of the liver circulation on the development of SFSS after EH in a porcine model. METHODS: Eighteen pigs were randomly divided into two groups: group A has received EH (75%-80%) without splenectomy, and group B with EH and simultaneous splenectomy was carried out...

In the US population of 300 million, 3 million have heart failure with reduced ejection fraction and 300,000 have advanced heart failure. Long-term mechanical circulatory support will, within the next decade, be recommended to 30,000 patients annually in the USA, 3000 undergo heart transplantation annually. What do these advances mean for persons suffering from advanced heart failure and their loved ones/caregivers? In this perspective article, we discuss - by exemplifying a case report of a 27-year-old man receiving a Total Artificial Heart - a practice concept of modern medicine that fully incorporates the patient's personhood perspective which we have termed Relational Medicine™...
