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 ...
The nodes are commonly indicative of subacute bacterial endocarditis. [3] 10–25% of endocarditis patients will have Osler's nodes. [4] Other signs of endocarditis include Roth's spots and Janeway lesions. The latter, which also occur on the palms and soles, can be differentiated from Osler's nodes because they are non-tender.

Antibiotics are administered to patients with certain heart conditions as a precaution, although this practice has changed in the US, with new American Heart Association guidelines released in 2007, [1] and in the UK as of August 2018 due to new SDCEP advice in line with the NICE guidelines. Everyday tooth brushing and flossing will similarly ...
Infective endocarditis used to be classified into groups like acute and subacute based on how quickly the infection developed, but nowadays the key is to identify that microbial cause of infection and to treat it as effectively as possible. Viridans Streptococci is the most common cause.
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]
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 ...
In some cases, vegetations form on the mitral leaflets as a result of endocarditis, an inflammation of the heart tissue. Mitral stenosis is uncommon and not as age-dependent as other types of valvular disease. [1] Mitral insufficiency can be caused by dilation of the left heart, often a consequence of heart failure.
Janeway lesions are rare, non-tender, small erythematous or haemorrhagic macular, papular or nodular lesions on the palms or soles only a few millimeters in diameter that are associated with infective endocarditis and often indistinguishable from Osler's nodes. [1] [2]
