Refractory heart failure typically requires costly long-term, continuous intravenous inodilator infusions while patients await mechanical circulatory support or cardiac transplantation. The combined angiotensin receptor blocker-neprilysin inhibitor, sacubitril/valsartan, is a novel therapy that can increase levels of endogenous vasoactive peptides. This therapy has been recommended as an alternative agent in patients with chronic heart failure with reduced ejection fraction and New York Heart Association class II-III symptoms...

OBJECTIVE: Hyperkalemia affects up to 10% of hospitalized patients and, if left untreated, can lead to serious cardiac arrhythmias or death. Although hyperkalemia is frequently encountered in the emergency department (ED), and is potentially life-threatening, standard of care for the treatment is poorly defined, with little supporting evidence. The main objectives of this observational study are to define the overall burden of hyperkalemia in the ED setting, describe its causes, the variability in treatment patterns and characterize the effectiveness and safety of ED standard of care therapies used in the United States...

Aims: In patients with aortic stenosis (AS), risk stratification for aortic valve replacement (AVR) relies mainly on valve-related factors, symptoms and co-morbidities. We sought to evaluate the prognostic impact of a newly-defined staging classification characterizing the extent of extravalvular (extra-aortic valve) cardiac damage among patients with severe AS undergoing AVR. Methods and results: Patients with severe AS from the PARTNER 2 trials were pooled and classified according to the presence or absence of cardiac damage as detected by echocardiography prior to AVR: no extravalvular cardiac damage (Stage 0), left ventricular damage (Stage 1), left atrial or mitral valve damage (Stage 2), pulmonary vasculature or tricuspid valve damage (Stage 3), or right ventricular damage (Stage 4)...

BACKGROUND: The benefits of exercise rehabilitation for people with heart failure (HF) are well established. In Australia, little is known about how the guidelines around exercise rehabilitation for people with HF are being implemented in clinical practice. Furthermore, it is unknown what organisational barriers are faced in providing exercise rehabilitation programs for this population. The aim of this study is to provide an updated review of exercise rehabilitation services for people with HF in Australia and to identify perceived organisational barriers to providing these services...

OBJECTIVE: To explore the genetic etiology of fetuses with ventricular septal defects (VSD) using chromosomal microarray analysis (CMA). METHODS: A total of 248 fetuses were divided into isolated VSD group, VSD with other cardiac and/or great vessels malformation group, VSD with extra-cardiac anomalies group (including malformation and sonographic soft markers), and VSD with both cardiac and extra-cardiac anomalies group. Standard karyotyping was carried out for all fetuses, and CMA was performed for 6 fetuses with an abnormal karyotype and a proportion of fetuses with a normal karyotype...

Background -High-sensitivity cardiac troponin testing may improve the risk-stratification and diagnosis of myocardial infarction, but concentrations can be challenging to interpret in patients with renal impairment and the effectiveness of testing in this group is uncertain. Methods -In a prospective multi-center study of consecutive patients with suspected acute coronary syndrome, we evaluated the performance of high-sensitivity cardiac troponin I in those with and without renal impairment (estimated glomerular filtration rate <60mL/min/1...

We report a case of a patient presenting with abdominal pain after cardiac surgery who was noted on point-of-care ultrasound (POCUS) to have pericardial and pleural effusion, in addition to ascites. The most notable findings were pleural and pericardial effusions, which combined with symptomatology met criteria for postpericardiotomy syndrome. Point-of-care ultrasound expedited the diagnosis of a pericardial effusion with impending tamponade and transfer for pericardiocentesis and placement of pericardial drain...

This study examined the effects of stimulating and sedative music on ratings of perceived exertion (RPE), heart rate (HR), blood pressure (BP), and feeling status during exercise in cardiac rehabilitation (CR) patients. Twenty-two male and female older adults age 64 ± 8.0 y currently enrolled in phase III CR completed the study. Repeated measures crossover designs guided data collection. The manipulated independent variable was music condition (sedative, stimulating, and non-music control). The dependent variables were RPE, BP, HR, and feeling status with each represented by four repeated measures ANOVAs over time via SAS 9...

BACKGROUND: Genetic and epigenetic programs regulate dramatic structural changes during cardiac morphogenesis. Concurrent biomechanical forces within the heart created by blood flow and pressure in turn drive downstream cellular, molecular and genetic responses. Thus, a genetic-morphogenetic-biomechanical feedback loop is continually operating to regulate heart development. During the evolution of a congenital heart defect, concomitant abnormalities in blood flow, hemodynamics, and patterns of mechanical loading would be predicted to change the output of this feedback loop, impacting not only the ultimate morphology of the defect, but potentially altering tissue-level biomechanical properties of structures that appear structurally normal...

BACKGROUND: Continuous flow (CF) left ventricular assist devices (LVADs) improve survival in end-stage heart failure patients who are ineligible for cardiac transplantation. Their use in this population (referred to as destination therapy) is increasing in many countries, yet they are not routinely funded for this indication in Canada. We assessed the cost-effectiveness of destination therapy CF-LVADs from the perspective of the Canadian health care payer. METHODS: A Markov model was used to project the outcomes and costs of 2 treatment pathways, CF-LVAD implantation and medical management alone, in an end-stage heart failure patient cohort ineligible for transplantation...

Pediatric cardiac anesthesiology has evolved as a subspecialty of both pediatric and cardiac anesthesiology and is devoted to caring for individuals with congenital heart disease ranging in age from neonates to adults. Training in pediatric cardiac anesthesia is a second-year fellowship with variability in both training duration and content and is not accredited by the Accreditation Council on Graduate Medical Education. Consequently, in this article and based on the Accreditation Council on Graduate Medical Education Milestones Model, an expert panel of the Congenital Cardiac Anesthesia Society, a section of the Society of Pediatric Anesthesiology, defines 18 milestones as competency-based developmental outcomes for training in the pediatric cardiac anesthesia fellowship...

Assessment of cardiac (123)I-mIBG uptake relies on the heart-to-mediastinal ratio (HMR) derived from planar images. We have developed novel semi-automated quantitative methodologies for assessing HMR from single photon emission computed tomography (SPECT) images using a dedicated cardiac multi-pinhole SPECT/computerized tomography (CT) system and determined the lower limit of normal (LLN) SPECT-derived HMR and the correlation to planar-derived HMR. Methods: Twenty-one healthy volunteers were injected with (123)I-meta Iodobenzylguanidine ((123)I-mIBG) and imaged using two different cameras...

Early reperfusion of ischemic cardiac tissue increases inflammatory cell infiltration which contributes to cardiomyocyte death and loss of cardiac function, referred to as ischemia/reperfusion (IR) injury. Neutrophil- and mast cell-derived proteases, cathepsin G (Cat.G) and chymase, are released early after IR, but their function is complicated by potentially redundant actions and targets. This study investigated whether a dual inhibition of Cat.G and chymase influences cardiomyocyte injury and wound healing after experimental IR in mice...

Fetoscopic endotracheal occlusion (FETO) is a prenatal treatment that may increase survival in severe congenital diaphragmatic hernia (CDH). In the USA, FETO is offered for isolated severe left-sided CDH in the context of an FDA-approved feasibility study. FETO in non-isolated cases of severe CDH is only performed with a compassionate use exemption from US regulatory bodies. Anomalies frequently associated with CDH include congenital cystic lesions of the lung and cardiac defects. We describe two cases of non-isolated severe left-sided CDH that underwent prenatal FETO, survived after birth and underwent postnatal surgical repair...

Background:In silico modeling could soon become a mainstream method of pro-arrhythmic risk assessment in drug development. However, a lack of human-specific data and appropriate modeling techniques has previously prevented quantitative comparison of drug effects between in silico models and recordings from human cardiac preparations. Here, we directly compare changes in repolarization biomarkers caused by dofetilide, dl-sotalol, quinidine, and verapamil, between in silico populations of human ventricular cell models and ex vivo human ventricular trabeculae...

Much of our understanding of the thermal physiology of intertidal organisms comes from experiments with animals acclimated under constant conditions and exposed to a single heat stress. In nature, however, the thermal environment is more complex. Aerial exposure and the unpredictable nature of thermal stress during low tides may be critical factors in defining the thermal physiology of intertidal organisms. In the fingered limpet, Lottia digitalis, we investigated whether upper temperature tolerance and thermal sensitivity were influenced by the pattern of fluctuation with which thermal stress was applied...

Importance: Coronary artery bypass grafting (CABG) is scheduled to become a mandatory Medicare bundled payment program in January 2018. A contemporary understanding of 90-day CABG episode payments and their drivers is necessary to inform health policy, hospital strategy, and clinical quality improvement activities. Furthermore, insight into current CABG payments and their variation is important for understanding the potential effects of bundled payment models in cardiac care. Objective: To examine CABG payment variation and its drivers...
