Libman–Sacks endocarditis (often misspelled Libmann-Sachs) is a form of nonbacterial endocarditis that is seen in association with systemic lupus erythematosus. It is one of the most common heart-related manifestations of lupus (the most common being inflammation of the fibrous sac surrounding the heart).
It was first described by Emanuel Libman and Benjamin Sacks at Mount Sinai Hospital in New York City in 1924. The association between Libman–Sacks endocarditis and antiphospholipid syndrome was first noted in 1985.
The vegetations are small and formed from strands of fibrin, neutrophils, lymphocytes, and histiocytes. The mitral valve is typically affected, and the vegetations occur on the ventricular and atrial surface of the valve. Libman-Sacks lesions rarely produce significant valve dysfunction and the lesions only rarely embolize.
