BACKGROUND: Cardiac allograft vasculopathy (CAV) remains one of the main long-term complications after heart transplantation. We performed a systematic review focused on articles published in the previous 6 years to reappraise the novel evidences supporting risk-factors, pathology, prevention and treatment of CAV. METHODS: We identified a search string for a literature search on PubMed. We excluded articles specifically focused on diagnosis/biomarkers/imaging only or complications of other diseases...

Bioengineering of a functional cardiac tissue composed of primary cardiomyocytes has great potential for myocardial regeneration and in vitro tissue modeling. However, its applications remain limited because the cardiac tissue is a highly organized structure with unique physiologic, biomechanical, and electrical properties. In this study, we undertook a proof-of-concept study to develop a contractile cardiac tissue with cellular organization, uniformity, and scalability by using three-dimensional (3D) bioprinting strategy...

Extracorporeal membrane oxygenation (ECMO) has been used increasingly for both respiratory and cardiac failure in adult patients. Indications for ECMO use in cardiac failure include severe refractory cardiogenic shock, refractory ventricular arrhythmia, active cardiopulmonary resuscitation for cardiac arrest, and acute or decompensated right heart failure. Evidence is emerging to guide the use of this therapy for some of these indications, but there remains a need for additional evidence to guide best practices...

OBJECTIVES: Central veno-arterial extracorporeal membrane oxygenation (C-VA-ECMO) provides temporary cardiorespiratory support for patients in heart failure who cannot be weaned from cardiopulmonary bypass successfully. Outcomes are influenced by the reversibility of the initial insult and complications of the technique. METHODS: The authors reviewed their single-center experience over the last 8 years to inform future practice. The study included all patients supported with C-VA-ECMO after cardiothoracic surgery between January 2008 and July 2016...

BACKGROUND: Acute cellular rejection (ACR) is a common complication in the first year after heart transplantation (HT). Routine surveillance for ACR is undertaken by endomyocardial biopsy (EMB). Measurement of cardiac troponins (cTn) in serum is an established diagnostic test of cardiac myocyte injury. This systematic review aimed to determine whether cTn measurement could be used to diagnose or exclude ACR. METHODS: PubMed, Google Scholar and the JHLT archive were searched for studies reporting the result of a cTn assay and a paired surveillance EMB...

The prevalence of chronic heart failure (CHF) is steadily increasing. Both sexes are affected, with significant differences in etiology, epidemiology and clinical presentation, prognosis, comorbidities, and response to treatment. Women tend to develop CHF at a more advanced age, present more often with HF with preserved ejection fraction, are more symptomatic, and have a worse quality of life than men, but also a better prognosis. In women, CHF has more frequently a non-ischemic etiology, and arterial hypertension and diabetes mellitus are leading comorbidities...

Children are at increased risk of developing metabolic syndrome (MS) after kidney transplantation, which contributes to long-term cardiovascular (CV) morbidities and decline in allograft function. While MS in the general population occurs due to excess caloric intake and physical inactivity, additional chronic kidney disease and transplant-related factors contribute to the development of MS in transplant recipients. Despite its significant health consequences, the interplay of the individual components in CV morbidity in pediatric transplant recipients is not well understood...

BACKGROUND: Portopulmonary hypertension (PPH) is a relatively rare but well-recognized complication of end-stage liver disease. Moderate or severe PPH (mean pulmonary artery pressure [mPAP] ≥ 35 mmHg) is usually a contraindication for liver transplantation due to high operation-related mortality. Here, we report on a patient with moderate PPH whose condition was successfully managed with a phosphodiesterase type 5 (PDE5) inhibitor (tadalafil) and prostaglandin E1, who experienced rapid improvement of PPH after living-donor liver transplantation (LDLT)...

Cardiac tamponade caused by perforation of the cardiac wall is a rare complication related to central venous catheter (CVC) placement. A 71-year-old female with a previous history of moderate aortic stenosis and kidney transplantation was admitted to hospital due to global heart failure and worsening of allograft function. Intensified hemodialysis was commenced through a CVC placed in the right subclavian vein. Chest radiography revealed catheter tip in the right atrium and no signs of pneumothorax. Thorough diagnostics outruled immediate life-threatening conditions, such as myocardial infarction and pulmonary embolism...

Background: Cardiovascular complications are the leading cause of mortality in end-stage renal disease (ESRD) patients. This study aimed to evaluate the efficacy of kidney transplantation on the cardiovascular status in ESRD patients. Methods: During 2012 to 2014 and in a cross-sectional study, 181 patients were randomly selected for this study. All patients were followed for periods of 6 and 12 months after kidney transplantation. The patients with ESRD and kidney transplant recipients; the patients with left ventricle ejection fraction<50%, left ventricular hypertrophy, mitral valve regurgitation and tricuspid valve regurgitation were included to study and the patients with kidney transplant rejection, myocardial infarction, high blood pressure with treatment-resistant, high blood pressure and addicted patients were censored...

BACKGROUND: Controlled donation after cardiac death (CDCD) is increasingly common for liver transplantation due to donor shortage. However, the outcomes, in terms of grafts and recipients, remain unclear. The current study is a systematic review and meta-analysis that compared CDCD with donation after brain death (DBD). METHODS: We conducted an electronic search of MEDLINE, EMBASE, and the Cochrane Database (from January 2007 to May 2017). Studies reporting Maastricht category III or IV CDCD liver transplantation were screened for inclusion...

Hereditary hemochromatosis (HH) can cause cirrhosis and hepatocellular carcinoma (HCC), but the frequency of these complications is controversial. To address this question, we reviewed the experience with HH at an academic medical center that is the sole liver transplantation center in a state with a population that is >90% Caucasian. The records of all subjects with International Classification of Diseases, Ninth Revision, code 275, "disorders of iron metabolism" seen at the University of Iowa Hospitals and Clinics between January 1, 2004 and December 31, 2014 were reviewed, and HFE C282Y homozygotes and C282Y/H63D compound heterozygotes were identified...

INTRODUCTION: As the population in the United States continues to age, an increase in the number of potential DCD donors with advanced chronological age can be expected. The aim of this study was to analyze a multi-institutional experience in liver transplantation using DCD donor age ≥50 years. METHODS: All DCD LT performed at Mayo Clinic Florida, Mayo Clinic Rochester and Mayo Clinic Arizona from 2002-2016 were included. Recipients of DCD LT were divided into 2 groups: those with donor age ≥50 years(N=155) and those with donor age <50 years(N=316)...

OBJECTIVES: An optimal initial graft function after living-donor liver transplant depends on optimal graft hemodynamics. Nonmechanical impediments to free hepatic venous outflow, due to elevated central venous pressure, may obstruct the "functional" hepatic venous outflow. Here, we evaluated whether central venous pressure affected early graft function and outcomes in adult living-donor liver transplant recipients. MATERIALS AND METHODS: This prospective observational study included 61 living-donor liver transplant recipients without technical complications who received transplants from August 2013 to November 2014...

Severe heart failure is increasingly being managed by cardiac transplantation, and in some cases mechanical support devices serve as destination therapies. Left ventricular assist devices (LVADs) were approved for destination therapy for end stage heart failure patients before the more advanced total artificial heart modality became available. One common complication of mechanical assist device placement is acute kidney injury. Historically, patients with mechanical support devices have had to have inpatient hemodialysis until combined heart kidney transplant...

BACKGROUND: Ischemic type biliary lesions arise most frequently after DCD liver transplantation and result in high morbidity and graft loss. Many DCD grafts are discarded out of fear for this complication. In theory, microvascular thrombi deposited during donor warm ischemia might be implicated in ITBL pathogenesis. Herein, we aim to evaluate the effects of the administration of either heparin or the fibrinolytic drug TPA as means to improve DCD liver graft quality and potentially avoid ITBL...

The objective of this study was to determine the incidence, risk factors, outcome, and clinical significance of pericardial effusion (PE). We retrospectively analyzed outcomes of 272 pediatric patients undergoing their first hematopoietic stem cell transplantation (HSCT) from 1998 to 2016. In total, 15% (3/20) and 5.9% (15/252) of autologous and allogeneic HSCT recipients, respectively, were identified with PE. However, there was no statistically significant difference in the incidence of PE between the 2 groups...

BACKGROUND: Acute kidney injury (AKI) is a common complication after liver transplantation and more frequently observed when high-risk grafts, such as DCD grafts are used. Our aim was to investigate the impact of the ischemia periods on development of AKI in DCD liver transplantation. METHODS: We performed a 2-center retrospective study with 368 DCD graft-recipients. Donor warm ischemia time (DWIT) was divided into agonal phase (withdrawal of life-support - cardiac arrest) and asystolic phase (cardiac arrest - start cold perfusion)...
