Infective Endocarditis (IE) is the infection of heart valves. [6] Previous beliefs were held that IE can be induced from dental procedures due to the invasive nature of treatment, therefore antibiotics were widely prescribed before dental treatment to prevent this.
Infective endocarditis is an infection of the endothelium lining of the heart. [5] Infective endocarditis is known to dentists as a post-operative infection and is very serious and life-threatening, especially to patients at high risk of developing the disease, due to a weakened heart.
Updated (2023) Modified Duke Criteria for Infective Endocarditis: Infective endocarditis (IE) is a life-threatening condition and the Duke criteria (established in 1994 and revised in 2000) has been fundamental for the diagnosis of the disease. However, the landscape of micro-biology, diagnostics, epidemiology, and treatment for lE has evolved ...
S. sanguinis may gain entrance to the bloodstream when opportunity presents (dental cleanings and surgeries) and colonize the heart valves, particularly the mitral and aortic valves, where it is the most common cause of subacute bacterial endocarditis. For this reason, oral surgeons often prescribe a short course of antibiotics to be taken a ...
Based on previous studies, though, the risk of endocarditis following cutaneous surgery is low and thus the use of antibiotic prophylaxis is controversial. Although this practice is appropriate for high-risk patients when skin is contaminated, it is not recommended for noneroded, noninfected skin.
S. gordonii therefore can rapidly colonize clean tooth surfaces, and S. gordonii along with related organisms comprise a high percentage, up to 70%, of the bacterial biofilm that forms on clean tooth surfaces. Generally harmless in the mouth, S. gordonii can cause acute bacterial endocarditis upon gaining access systemically.
Another form of sterile endocarditis is termed Libman–Sacks endocarditis; this form occurs more often in patients with lupus erythematosus and is thought to be due to the deposition of immune complexes. [2] Like NBTE, Libman-Sacks endocarditis involves small vegetations, while infective endocarditis is composed of large vegetations. [2]
Other strains of streptococci can cause subacute endocarditis as well. These include streptococcus intermedius, which can cause acute or subacute infection (about 15% of cases pertaining to infective endocarditis). [7] Enterococci from urinary tract infections and coagulase negative staphylococci can also be causative agents. [5]
