PURPOSE OF REVIEW: As the heart failure population continues to age, the need for definitive therapies such as ventricular assist devices (VADs) to extend life and alleviate suffering from end-stage disease directly increases. The goal of this article is to examine the ethical principles of autonomy, beneficence, non-maleficence, and justice within the context of long-term VAD patients. RECENT FINDINGS: Survival rates in VAD-implanted patients have improved in parallel with modernization of device design and surgical technique, reaching that of cardiac transplantation at 1 year post-procedure...

BACKGROUND: A previously under-recognized subset of hypertrophic cardiomyopathy (HCM) patients with left ventricular (LV) apical aneurysms is being identified with increasing frequency. However, risks associated with this subgroup are unknown. OBJECTIVES: The authors aimed to clarify clinical course and prognosis of a large cohort of HCM patients with LV apical aneurysms over long-term follow-up. METHODS: The authors retrospectively analyzed 1,940 consecutive HCM patients at 2 centers, 93 of which (4...

Despite improvements in pharmacological therapy and pacing, prognosis in advanced heart failure (HF) remains poor, with a 1-year mortality of 25-50%. While heart transplantation provides excellent survival and quality of life for eligible patients, only a few can be offered this treatment due to shortage of donor organs. Implantable left ventricular assist device (LVAD) technology has improved considerably, and the currently used continuous flow devices may last >10 years in a patient. LVADs are being used increasingly both as bridge-to-transplantation and as destination therapy...

Because the human heart has limited potential for regeneration, the loss of cardiomyocytes during cardiac myopathy and ischaemic injury can result in heart failure and death. Stem cell therapy has emerged as a promising strategy for the treatment of dead myocardium, directly or indirectly, and seems to offer functional benefits to patients. The ideal candidate donor cell for myocardial reconstitution is a stem-like cell that can be easily obtained, has a robust proliferation capacity and a low risk of tumour formation and immune rejection, differentiates into functionally normal cardiomyocytes, and is suitable for minimally invasive clinical transplantation...

Myocardial dysfunction and heart failure are common in pediatric patients with congenital and acquired heart disease. Alkaline phosphatase (AP) has been suggested as a biomarker for myocardial dysfunction after Fontan operation. We hypothesized that pediatric patients with myocardial dysfunction requiring orthotopic heart transplant (OHT) have diminished AP compared to normal. A retrospective review was performed in all patients who underwent OHT at Arkansas Children's Hospital between January 2007 and October 2012...

BACKGROUND: Cardiac allograft vasculopathy (CAV) remains an important cause of graft failure after heart transplantation (HT). Although many risk factors for CAV have been identified, there are no clinical prediction models that enable clinicians to determine each recipient's risk of CAV. METHODS: We studied a cohort of 14,328 heart transplant recipients whose data were reported to the International Society for Heart and Lung Transplantation Registry between 2000 and 2010...

AIMS: Decreased arylesterase (ArylE) activity of paraoxonase-1, a HDL-associated protein with anti-inflammatory and antioxidant properties, has been associated with increased risk of cardiac events in patients with ischaemic heart failure (HF). We aim to investigate the prognostic significance of changes in serum ArylE activity over time. METHODS AND RESULTS: We examined the association between baseline and follow-up serum ArylE activity and HF outcomes (death, cardiac transplantation, or ventricular assist device implantation) in 299 patients with HF enrolled in a prospective cohort study from January 2008 to July 2009, with 145 patients having available follow-up levels at 1 year...

BACKGROUND: Left ventricular assist device (LVAD) implantation as a bridge to cardiac transplantation (BTT) is an effective treatment for end-stage heart failure patients. Currently, there is an increasing number of patients with a LVAD who need a heart and kidney transplant (HKT). Little is known of the prognostic outcomes in these patients. This study was undertaken to determine whether an equivalent outcome would be present in HKTs as compared to a non-LVAD primary HKT cohort. METHODS: We reviewed the United Network for Organ Sharing database from 2004 to 2013...

Prior to starting clinical cardiac allotransplantation, cardiac xenotransplantation was performed in human in 1960s. In 1964, Hardy performed cardiac transplantation using a chimpanzee heart and Bailey performed cardiac transplantation using a baboon heart to an infant with hypoplastic left heart. The use of cyclosporine has greatly improved the outcome of clinical cardiac transplantation and cardiac allotransplantation became an established treatment strategy for the patients with end-stage heart failure. Although concordant cardiac xenotransplantation from a primate to a human may be successfully performed using current immunosuppressive regimen, a primate heart is not a good candidate for cardiac xenograft due to animal light issues and its size...

Despite advances in cardiovascular biology and medical therapy, heart disorders are the leading cause of death worldwide. Cell-based regenerative therapies become a promising treatment for patients affected by heart failure, but also underline the need for reproducible results in preclinical and clinical studies for safety and efficacy. Enthusiasm has been tempered by poor engraftment, survival and differentiation of the injected adult stem cells. The crucial challenge is identification and selection of the most suitable stem cell type for cardiac regenerative medicine...

BACKGROUND: Increased length of stay (LOS) during acute heart failure (HF) hospitalization is associated with readmission and mortality. METHODS: The ESCAPE trial data were utilized to identify determinants and post-discharge outcomes of patients with acute systolic HF requiring longer-than-average LOS (≥7 days). The study endpoints were 6‑month all-cause mortality, all-cause rehospitalization, and the composite endpoint of death, cardiac rehospitalization, and cardiac transplant...

Early primary graft failure after pediatric orthotopic heart transplantation (OHT) has a high mortality rate and can occur due to several causes including but not limited to prolonged graft ischemia time, suboptimal preimplant myocardial preservation, hyperacute rejection, and maladaptation of the graft to the host's hemodynamic status. Mechanical circulatory support with either extracorporeal membrane oxygenation (ECMO) or ventricular assist device has been used for the rescue of primary graft failure in pediatric patients after heart transplant...

Congestive heart failure (CHF) is one of the major causes of death and occurs in more than 15,000,000 patients worldwide. The incidence is expected to increase in parallel with the aging population. Most current therapies for CHF are medications, and biventricular pacing implantation as appropriated by cardiologists, or surgical interventions. The heart transplantation for indicated patients is still gold standard surgery although the 10-year survival rate is approximately 60% based on the worldwide data. However, the cardiac transplantation remains epidemiologically insignificant because of donor pool limitations...

AIM: To evaluate the possible relationship between high levels of CA-125 and long-term prognosis in chronic heart failure patients after they undergo a cardiac transplantation (CT). MATERIALS & METHODS: We retrospectively studied all patients who underwent a CT and had a previous determination of CA-125. Congestive patients and those whose survival was <1 year after CT were excluded. RESULTS: Of 55 patients, 23 had elevated CA-125 levels (>35 U/ml)...

Heart failure often develops after acute myocardial infarction because the injured myocardial tissue fails to recover or regenerate. Stem cell transplantation using adult cell sources, such as adipose-derived stromal vascular fraction (SVF), draws extensive attention. In this study, SVF cells were isolated from rat adipose tissue and cultivated on enzyme-crosslinked gelatin hydrogels. Morphological features of cell development and spontaneous beating behavior from these cells were observed and recorded. Cardiac phenotypes were characterized via immunofluorescence staining, and the expression of cardiac-specific genes was measured via RT-PCR...

Heart failure (HF) is an important cardiovascular disease because of its increasing prevalence, significant morbidity, high mortality and rapidly expanding health care costs. The number of HF patients is increasing worldwide and Korea is no exception. Temporal trends of four representative Korean hospitalized HF registries-the Hallym HF study, the Korean Multicenter HF study, the Korean Heart Failure (KorHF) registry and the Korean Acute Heart Failure (KorAHF) registry showed mild survival improvement reflecting overall HF patient care development in Korea despite the increased severity of enrolled patients with higher incidence of multiple comorbidities...

Endothelial dysfunction precedes the clinical stage of atherosclerotic disease and is recognized as an additional risk factor when detecting symptomatic patients. Endothelial function is largely mediated by nitric oxide, and this vasodilatory mechanism is also responsible for the venous and arterial dilatation required to obtain and maintain an erection. The physiological effects and clinical aspects of sexual function have been extensively studied and reported in patients who have angina or who have experienced a myocardial infarction and in those who have undergone coronary artery bypass graft surgery or heart transplant...

BACKGROUND: Heart transplantation remains the gold standard for end-stage heart failure, with current ex vivo organ storage times limited to 4 to 6 h before critical tissue damage occurs. Many preservation solutions exist in an attempt to limit both ischemic and reperfusion damage. In order to compare the effects of various storage solutions, mitochondrial function can be used to provide a sensitive analysis of cellular metabolic function. METHODS: Experimental plates were seeded with cardiac myoblasts and kept in suspended animation for either 4 or 8 h at either 4(o) or 21 °C, in Celsior®, Perfadex®, or Somah storage solutions...
