What is non infective endocarditis?
Non-infective endocarditis, also known as non-bacterial thrombotic endocarditis (NBTE) or aseptic endocarditis, refers to a rare condition characterised by formation of sterile vegetations. Without treatment, these can lead to valve dysfunction, heart failure, systemic embolism and death.
Why is marantic endocarditis called?
Nonbacterial thrombotic endocarditis (NBTE) is a form of endocarditis in which small sterile vegetations are deposited on the valve leaflets. Formerly known as marantic endocarditis, which comes from the Greek marantikos, meaning “wasting away”.
How is NBTE diagnosed?
There are no pathognomonic signs and symptoms that allow for the diagnosis of NBTE. Previously Mckay and Wahler [27] outlined a triad consisting of: (1) a disease process known to be associated with NBTE, (2) presence of a heart murmur and (3) evidence of multiple systemic emboli.
What are Osler nodes?
Osler nodes and Janeway lesions are cutaneous manifestations of endocarditis, a disease most commonly arising from a bacterial or fungal infection of the cardiac endocardium.[1] Osler nodes are tender, purple-pink nodules with a pale center and an average diameter of 1 to 1.5 mm.[2] They are generally found on the …
What is Marantic thrombosis?
Abstract. The term nonbacterial thrombotic endocarditis (NBTE), or marantic endocarditis, refers to a spectrum of lesions ranging from microscopic aggregates of platelets to large vegetations on previously undamaged heart valves (most often aortic and mitral) in the absence of a bloodstream bacterial infection.

What is nonbacterial thrombotic endocarditis?
Nonbacterial thrombotic endocarditis (NBTE), formerly known as marantic endocarditis, is a potentially overlooked condition that involves the formation of sterile, fibrin vegetations on heart valve leaflets.
Is nonbacterial thrombotic endocarditis associated with systemic lupus erythematosus?
Nonbacterial thrombotic endocarditis (NBTE), also known as marantic endocarditis, is associated with malignancy and autoimmune disorders [ 20 ]. Libman–Sacks (L-S) endocarditis is an atypical form of NBTE associated with systemic lupus erythematosus.
What causes marantic (nonbacterial) endocarditis?
There are several causes of marantic (nonbacterial thrombotic) endocarditis, a condition characterized by platelet aggregates or vegetations on previously undamaged heart valves (most often aortic and mitral) without evidence of bacteremia.
What is non-obstructive thrombotic vegetations (NBTE)?
NBTE consists of thrombotic vegetations of heart valves without underlying valve disease ( Figure 2.5 ). NBTE is sterile. No organisms or inflammation are found in NBTE. NBTE is found in 0.3-9.3% of autopsies [ 147, 148 ].
