RESUMO
This review addresses current views on prevention of infectious endocarditis (IE). History of establishing the concept of antibacterial prophylaxis (ABP), major approaches, and substantiation of changes in ABP in recent years are described. Recent international and national guidelines are highlighted, specifically, guidelines of the European Society of Cardiologists, American Heart Association/American College of Cardiology, and the Japanese Circulation Society. The review presents critical evaluation of previously approved international guidelines, including analysis of the effect of partial or complete ABP restriction on IE morbidity and incidence of complications. Special attention is paid to awareness of practitioners, particularly dentists, about ABP issues in their practice. Aspects of validity and key features of preventive approaches in implanting cardiac electronic devices and transcatheter aortic valve implantation are discussed.
