It is most commonly associated with systemic autoimmune conditions, notably systemic lupus erythematosus (SLE) and a...

Noninfectious endocarditis is best divided into inflammatory vegetation best illustrated by Libman Sacks lesions vs, in the alternative, a primary thrombotic vegetation also known both as marantic and, less commonly in literature, as murantic endocarditis and associates with hypercoagulable states s...

What is the microscopic composition of the vegetations? If Non-thrombotic, Non-infectious, seems no role for anticoagulation.
