Brief Summary:
Infections often occur after ventricular assist devices (VADs) are placed. These infections can be very serious. The goal of this study is to understand why these infections occur. Bacteria (germs) normally live on our skin and in our noses. After surgery, they can infect the VAD. The investigators will collect cultures of your skin and nose before and after surgery. The investigators will compare these bacteria to bacteria that cause infections. Their genes will be compared to see which ones help the bacteria cause infection.
Detailed Description:
Infections are one of the most serious of ventricular assist device (VAD) related complications. Many of these infections are associated with significant patient morbidity and mortality. Diagnosis of these infections is often difficult due to the complicated nature of the patient's medical problems, the need for rapid institution of empiric antibiotic therapy and the lack of established criteria that define infection. Staphylococci are among the most common causes of VAD infections. The basis for this high incidence is not well understood but is believed to be in part due to inoculation of staphylococcal commensal flora into wound sites at the time of surgery or thereafter. The goals of this observational study are to develop a better understanding of the pathogenesis and epidemiology of Staphylococcus aureus and epidermidis-VAD infections as well as to develop a set of criteria that can be used to help diagnose the presence or absence of a VAD related infection.
This is a prospective, multi-center, observational study to identify risk factors associated with the development of VAD-related infections. Patients will be followed for up to one year following VAD implantation, time of death or transplantation, whichever comes first. There will be no randomization for this observational study.
