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 associated with 18% in-hospital mortality. [24] However, adult patients with congenital heart disease can have relatively lower mortality down to 5% due to younger age, right-sided endocarditis and management by multidisciplinary teams. As many as 50% of people with infective endocarditis may experience embolic ...
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]
Endocarditis is an inflammation of the inner layer of the heart, the endocardium.It usually involves the heart valves.Other structures that may be involved include the interventricular septum, the chordae tendineae, the mural endocardium, or the surfaces of intracardiac devices.
Primary infectious disease in the pre-antibiotic era was found most commonly secondary to pneumonia or endocarditis, whereas pneumonia or meningitis have been found more commonly in the modern era. Other risk factors that contribute to the development of purulent pericarditis include recent thoracic surgery, chronic renal failure, malignancy ...
The HACEK organisms are a group of fastidious Gram-negative bacteria that are an unusual cause of infective endocarditis, which is an inflammation of the heart due to bacterial infection. [1] HACEK is an abbreviation of the initials of the genera of this group of bacteria: Haemophilus , Aggregatibacter (previously Actinobacillus ...
Linezolid appears to be a reasonable therapeutic option for infective endocarditis caused by multi-resistant Gram-positive bacteria, despite a lack of high-quality evidence to support this use. [36] [37] Results in the treatment of enterococcal endocarditis have varied, with some cases treated successfully and others not responding to therapy.
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 ...
