BACKGROUND: To investigate the clinical characteristics, surgical interventions and outcomes of arteriovenous fistula (AVF) aneurysms, we retrospectively analyzed patients on regular hemodialysis (HD). METHODS: We conducted a cohort study of all patients with HD access who presented with AVF aneurysms and underwent operative procedures over a 11-year period. Patients' demographics, comorbidities, vascular access characteristics, management of aneurysms, complications and outcomes were analyzed...

BACKGROUND: Amiodarone remains the preferred agent for the treatment and prevention of life-threatening ventricular arrhythmias in patients with end-stage heart failure. While several reports suggest that pre-operative amiodarone exposure worsens outcomes in heart transplant recipients, other studies have failed to validate this relationship. We sought to clarify this issue by performing a meta-analysis of the available literature surrounding this topic. METHODS: We searched Medline, SCOPUS and the Cochrane Central Register of Controlled Trials through December 15th 2016, as well as proceedings from related conferences over the prior 3years...

AIMS: Hepatitis C virus (HCV) has been associated with cardiomyopathies. Former anti-HCV therapies employing interferon could have serious side effects in patients with advanced heart failure since interferon may adversely impact upon cardiac function. We, therefore, examined whether the novel, interferon-free and highly virus-selective anti-HCV combination therapy might be applicable even in advanced or end-stage heart failure. METHODS AND RESULTS: In a retrospective series of HCV-positive patients admitted to our institution with suspected cardiac disease, coronary, valvular or hypertensive heart disease was diagnosed in 70/146 (47...

Increasing prevalence of obesity has led to a rise in the number of prospective obese heart and lung transplant recipients. The optimal management strategy of obese patients with end-stage heart and lung failure remains controversial. This review article discusses and provides a summary of the literature surrounding the impact of obesity on outcomes in heart and lung transplantation. Studies on transplant obesity demonstrate controversy in terms of morbidity and mortality outcomes and obesity pre-transplantation...

Domino heart transplant, wherein the explanted heart from the recipient of an en-bloc heart-lung is utilized for a second recipient, represents a unique surgical strategy for patients with end-stage heart failure. With a better understanding of the potential advantages and disadvantages of this procedure, its selective use in the current era can improve and maximize organ allocation in the United States. In this report, we reviewed the current status of domino heart transplantation.

Surgeries to correct congenital heart diseases are increasing in Brazil and worldwide. However, even with the advances in surgical techniques and perfusion, some cases, especially the more complex ones, can develop heart failure and death. A retrospective study of patients who underwent surgery for correction of congenital heart diseases with cardiopulmonary bypass (CPB) in a university tertiary-care hospital that died, showed infarction in different stages of evolution and scattered microcalcifications in the myocardium, even without coronary obstruction...

REVIEW
Amanda Cai, Howard J Eisen
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...

Purpose Women receiving trastuzumab with chemotherapy are at risk for trastuzumab-related cardiac dysfunction (TRCD). We explored the prognostic value of cardiac markers (troponins I and T, N-terminal prohormone of brain natriuretic peptide [NT-proBNP]) to predict baseline susceptibility to develop TRCD. We examined whether development of cardiac end points or significant left ventricular ejection fraction (LVEF) drop was associated with markers' increases. Patients and Methods Cardiac marker assessments were coupled with LVEF measurements at different time points for 533 patients from the Herceptin Adjuvant (HERA) study who agreed to participate in this study...

Low-level laser therapy (LLLT) has been targeted as a promising approach that can mitigate post-infarction cardiac remodeling. There is some interesting evidence showing that the beneficial role of the LLLT could persist long-term even after the end of the application, but it remains to be systematically evaluated. Therefore, the present study aimed to test the hypothesis that LLLT beneficial effects in the early post-infarction cardiac remodeling could remain in overt heart failure even with the disruption of irradiations...

Arrhythmogenic cardiomyopathy (AC) is a hereditary disease leading to sudden cardiac death or heart failure. AC pathology is characterized by cardiomyocyte loss and replacement fibrosis. Our goal was to determine whether cardiomyocytes respond to AC progression by pathological hypertrophy. To this end, we examined tissue samples from AC patients with end-stage heart failure and tissue samples that were collected at different disease stages from desmoglein 2-mutant mice, a well characterized AC model. We find that cardiomyocyte diameters are significantly increased in right ventricles of AC patients...

BACKGROUND: The use of left ventricular assist devices (LVADs) has gained significant importance for treatment of end-stage heart failure. Fast-track procedures are well established in cardiac surgery, whereas knowledge of their benefits after LVAD implantation is sparse. We hypothesized that ultra-fast-track anesthesia (UFTA) with in-theater extubation or at a maximum of 4 h. after surgery is feasible in Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS) level 3 and 4 patients and might prevent postoperative complications...

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...

We report a case of coronary-pulmonary artery fistula in a hemodialysis patient treated surgically. A 47-year-old man was admitted with chest pain and exertional dyspnea that progressively worsened over the previous 2 months. He had a history of end-stage renal disease and has been on hemodialysis for 5 years. Coronary angiography and computed tomography revealed coronary-pulmonary artery fistula that originated from both the left anterior descending coronary artery and the right coronary artery. Under cardiopulmonary bypass, we opened the pulmonary artery and closed the fistula...

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...

In Japan the 1st paracorporeal ventricular assist device (VAD) was implanted in 1980. Since then, more than 2,000 VADs were used. Small size continuous-flow VAD (CFVAD) was developed in 1990s, which dramatically improved safety and efficacy of long-term support. EVAHEART and DuraHeart, both of which were developed in Japan, were approved for health insurance coverage in 2011, followed by approval of HeartMate II in 2013 and Jarvik 2000 in 2014. Although these approvals were limited for bridge to transplantation, CFVADs gained rapid acceptance for treatment of end-stage heart failure...

Heart failure is a life-threatening disorder worldwide, and the current end-stage therapies for severe heart failure are replacement therapies such as ventricular-assist devices and heart transplantation. Although these therapies have been reported to be useful, there are many issues in terms of the durability, complications, limited donors, adverse effect of continuous administration of immunosuppressive agents, and high costs involved. Recently, regenerative therapy based on genetic, cellular, or tissue engineering techniques has gained attention as a new therapy to overcome the challenges encountered in transplantation medicine...

The number of patients with end-stage heart failure treated by a left ventricular assist device (LVAD) is dramatically increasing, because the LVAD has been widely accepted for its clinical results. According to the initiation of destination therapy, the prevalence of malignancy in patients with an LVAD is estimated to increase. In patients with LVADs, abdominal surgery for visceral malignancy is associated with technical difficulties because of the presence of an LVAD pump or the driveline which is located transversely in the preperitoneal space...

BACKGROUND: Left ventricular assist device (LVAD) has become an alternative treatment for end-stage heart failure patients. Series type of LVAD, as a novel LVAD, has attracted more and more attention. The hemodynamic effects of series type LVAD on aortic blood pattern are considered as its important characteristics; however, the precise mechanism of it is still unclear. METHODS: To clarify the hemodynamic effects of series type LVAD on aortic blood flow pattern, a comparative study on the aortic blood flow pattern and hemodynamic states were carried out numerically for two cases, including series type LVAD support and normal condition...
