Abstract
IE is a very complex disease with a serious prognosis. Despite
improved preventive strategies and rational antibiotic prescribing, the
incidence of IE has not decreased in the last three decades. In
contemporary population-based studies of IE in industrialized countries,
in-hospital mortality ranges from 15 to 22%, and 5-year mortality is
approximately 40%.
This lack of improvement in prognosis might be due to the fact that
IE is now occurring in old people, in patients unaware of having a cardiac
disease, in patients with prosthetic valves, and is being caused by
aggressive organisms such as Staphylococci.
Surgery for IE has been potentially lifesaving and is indicated in
approximately 50% of patients. Operating during inactive (healed) phase
of the disease process, in a sterile field, is highly desirable. If medical
treatment fails to eradicate the infection, however, or in conditions such
as cardiac failure, severe valvular dysfunction, embolism, abscess
formation, demonstration of large mobile vegetations on
echocardiography, fungal infection, or early PVE, expeditious operation,
in the face of an ongoing infection, may be warranted.
Early identification of patients who are at high risk of death or
complications of IE may offer the opportunity to improve the outcome of
this disease. Several studies have demonstrated that among the
complications of IE, congestive heart failure has the greatest impact on
prognosis.
The aim of this study was to evaluate the risk factors affecting the
early outcomes of surgical treatment of infective endocarditis.
