Non Bacterial Thrombotic Endocarditis

Non Bacterial Thrombotic Endocarditis •View is of inflow tract of left ventricle showing mitral valve with left atrium above and ventricle below. The larger valve leaflet on the left is the anterior one, and the other is the posterior leaflet. •Note the small discrete pink vegetations (arrows) along the line of closure, typical of non bacterial thrombotic endocarditis (NBTE). These thrombi are made of platelets. •NBTE occurs in any severe lethal disease, classically metastatic carcinomas and tuberculosis. The pathogenesis is unknown. The vegetations are prone to embolize.
