Clinical Echocardiography

Abstract

In recent years, there has been a change in the epidemiological profile of infective endocarditis (IE), with an increase in valvular endocarditis in elderly patients, often as a result of health care–associated procedures, both in patients with native valve disease and patients with prosthetic valves [1–3]. In developed countries, the currently listed predisposing factors for endocarditis are degenerative valve sclerosis, valve prostheses, intravenous drug abuse, and frequent use of invasive procedures [4, 5]. In developing countries, however, where the prevalence of rheumatic fever remains high, rheumatic valvular heart disease represents the main risk factor for IE [6].
