SdrF, a Staphylococcus epidermidis Surface Protein, Contributes to the Initiation of Ventricular Assist Device Driveline–Related Infections

SdrF, a Staphylococcus epidermidis Surface Protein, Contributes to the Initiation of Ventricular Assist Device Driveline–Related Infections

Staphylococcus epidermidis remains the predominant pathogen in prosthetic-device infections. Ventricular assist devices, a recently developed form of therapy for end-stage congestive heart failure, have had considerable success. However, infections, most often caused by Staphylococcus epidermidis, have limited their long-term use. The transcutaneous driveline entry site acts as a potential port...

Ventricular Assist Device-Specific Infections

Ventricular assist devices (VADs) have been shown to offer a significant survival benefit over medical therapy in patients with advanced heart failure. Despite significant advances in device technology and surgical technique, VAD-specific infections still remain among the most common causes of morbidity and mortality in patients with VADs. VAD-specific infections may involve the driveline exit ...

712Gram-negative associated Ventricular Assist Device infections

Prospective, multicenter study of ventricular assist device infections.

BACKGROUND Ventricular assist devices (VADs) improve survival and quality of life in patients with advanced heart failure, but their use is frequently complicated by infection. There are limited data on the microbiology and epidemiology of these infections. METHODS AND RESULTS One hundred fifty patients scheduled for VAD implantation were enrolled (2006-2008) at 11 US cardiac centers and foll...

Improvement 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...
