Nonvalvular Cardiovascular Device–Related Infections

Abstract

M ore than a century ago, Osler took numerous syndrome descriptions of cardiac valvular infection that were incomplete and confusing and categorized them into the cardiovascular infections known as infective endocarditis. Because he was both a clinician and a pathologist, he was able to provide a meaningful outline of this complex disease. Technical advances have allowed us to better subcategorize infective endocarditis on the basis of microbiological etiology. More recently, the syndromes of infective endocarditis and endarteritis have been expanded to include infections involving a variety of cardiovascular prostheses and devices that are used to replace or assist damaged or dysfunctional tissues (Table Taken together, infections of these novel intracardiac, arterial, and venous devices are frequently seen in medical centers throughout the developed world. In response, the American Heart Association's Committee on Rheumatic Fever, Endocarditis, and Kawasaki Disease wrote this review to assist and educate clinicians who care for an increasing number of patients with nonvalvular cardiovascular device-related infections. Because timely guidelines 1,2 exist that address the prevention and management of intravascular catheter-related infections, these device-related infections are not discussed in the present Statement.
