Nonbacterial thrombic endocarditis ( NBTE ) or marantic endocarditis is most commonly found on previously undamaged valves.

Like NBTE, Libman-Sacks endocarditis involves small vegetations, while infective endocarditis is composed of large vegetations.

Marantic endocarditis, also known as non-bacterial thrombotic endocarditis ( NBTE ), is the deposition of small sterile vegetations on valve leaflets.

NBTE may also occur in patients with cancers, particularly mucinous adenocarcinoma where Trousseau syndrome can be encountered.

As opposed to infective endocarditis, the vegetations in NBTE are small, sterile, and tend to aggregate along the edges of the valve or the cusps.

Also unlike infective endocarditis, NBTE does not cause an inflammation response from the body.

Typically NBTE does not cause many problems on its own, but parts of the vegetations may break off and embolize to the heart or brain, or they may serve as a focus where bacteria can lodge, thus causing infective endocarditis.

These immune complexes precipitate an inflammation reaction, which helps to differentiate it from NBTE.

Also unlike NBTE, Libman-Sacks endocarditis does not seem to have a preferred location of deposition and may form on the undersurfaces of the valves or even on the endocardium.

Due to the non-invasive nature of NBTE, clinical examination may or may not reveal a new murmur.

An embolic stroke may be the first feature to suggest the diagnosis of NBTE.
