Left ventricular assist device deactivation: ethical issues.
M ore than 5 million Americans live with the diagnosis of heart failure (American Heart Association, 2008). Within 1 year of diagnosis, about 20% of affected patients die; only 40%-60% of patients with heart failure survive 5 years after diagnosis (Costanza, Mills, & Wynne, 2008). For patients with intractable symptoms, a heart transplant is the standard surgical procedure. However, over 3,200 ...
متن کاملRegression of cellular hypertrophy after left ventricular assist device support.
BACKGROUND Although multiple studies have shown that the left ventricular assist device (LVAD) improves distorted cardiac geometry, the pathological mechanisms of the "reverse remodeling" of the heart are unknown. Our goal was to determine the effects of LVAD support on cardiac myocyte size and shape. METHODS AND RESULTS Isolated myocytes were obtained at cardiac transplantation from 30 faili...
متن کاملQuality of life and left ventricular assist device support.
More than 5 million Americans are living with heart failure, with an additional 500 000 cases diagnosed each year.1 Ongoing improvements in patient management will only increase the number of patients surviving to develop severe refractory heart failure (stage D). Approximately 5% to 10% of all heart failure patients are classified as stage D and defined as patients who continue to have symptom...
متن کاملImprovement of Left Ventricular Assist Device (LVAD) in Artificial Heart Using Particle Swarm Optimization
In this approach, the Left ventricular assist pump for patients with left ventricular failure isused. The failure of the left ventricle is the most common heart disease during these days. Inthis article, a State feedback controller method is used to optimize the efficiency of a samplingpump current. Particle Swarm Algorithm, which is a set of rules to update the position andvelocity, is applied...
متن کاملFungemia associated with left ventricular assist device support.
OBJECTIVE Infections remain an important complication of left ventricular assist device (LVAD) support. While relatively uncommon, fungal infections present a serious concern given a high association with adverse events including death. We sought to further characterize the epidemiology of fungemias during LVAD support. METHODS Retrospective review of 292 patients receiving LVAD support from ...
