BACKGROUND A rising number of patients are surgically treated for heart failure at the more advanced stage, thanks to the increasing use of left ventricular assist device (LVAD) as a reliable alternative to heart transplantation (HTx). However, it is still unknown whether differences exist between the two surgical approaches in the efficacy of rehabilitation programmes. Therefore, aim of this s...
The past five years have seen remarkable growth in the use of durable, continuous flow left ventricular assist devices (LVAD) with associated improvements in mortality, quality of life, functionality and end-organ function. To sustain the growth of this important therapy, the LVAD community must now address key issues focused around the costs of LVAD care, refined patient selection, and reducin...
Left ventricular assist device (LVAD) thrombosis remains a dreadful complication of mechanical circulatory support, with an incidence of 8-12% depending on the pump type and patient's comorbidities. Fibrinolysis may be considered early in pump thrombosis, but when contraindicated a pump exchange remains the only alternative. This short report documents an emergency LVAD exchange in a 55-year-ol...
AIMS The need for the left ventricular assist devices (LVAD) in patients with end-stage heart failure is well established, but prior to 2011, this was not available to patients in Kazakhstan. We describe the development of the sole LVAD programme in the context of a nascent heart transplantation programme and clinical outcomes for the first three years. METHODS AND RESULTS From November 2011 ...
AIM Pulsatile flow left ventricular assist devices (pf-LVADs) are being replaced by continuous flow LVADs (cf-LVADs) in patients with end-stage heart failure (HF). MicroRNAs (miRs) play an important role in the onset and progression of HF. Our aim was to analyze cardiac miR expression patterns associated with each type of device, to analyze differences in the regulation of the induced cardiac c...
BACKGROUND Inotrope use in heart failure treatment was associated with improved symptoms, but worse survival in clinical trials. However, these studies predated use of modern heart failure therapies. This study evaluates contemporary outcomes on long-term inotropes. METHODS AND RESULTS We collected baseline and postinotrope data on 197 patients discharged on inotropes between January 2007 and...
BACKGROUND Left ventricular (LV) assist devices (LVADs) can improve contractile strength and normalize characteristics of the Ca(2+) transient in myocytes isolated from failing human hearts. The purpose of the present study was to determine whether LVAD support also improves contractile strength at different frequencies of contraction (the force-frequency relationship [FFR]) of intact myocardiu...
INTRODUCTION Recently, the Food and Drug Administration approved implantable left ventricular assist devices (LVAD) as destination therapy (DT) for end-stage heart failure patients who are ineligible for cardiac transplantation. OBJECTIVE AND STUDY DESIGN This is a case series that describes the early results with DT LVAD at Duke University Medical Center (DUMC). An additional objective is to...
BACKGROUND Renal failure requiring renal replacement therapy (RRT) has detrimental effects on quality of life and survival of patients with continuous-flow left ventricular assist devices (CF-LVADs). Current guidelines do not offer a decision-making algorithm for CF-LVAD candidates with poor baseline renal function. Objective of this study was to identify risk factors associated with RRT after ...
Left ventricular assist device (LVAD)-supported patients are evaluated routinely with use of transthoracic echocardiography. Values of left ventricular unloading in this unique patient population are needed to evaluate LVAD function and assist in patient follow-up. We introduce a new M-mode measurement, the slope of the anterior mitral valve leaflet (SLAM), and compare its efficacy with that of...
