LIBMAN-SACK ENDOCARDITIS:

OVERVIEW:

Libman-sack endocarditis is the one of the cardiac manifestations of autoimmune systemic diseases most commonly Systemic Lupus Erythematosus. It may also be a finding in malignancy with the non-bacterial non-thrombotic involvement of the valves, most commonly the aortic and mitral valve. The most common complications include embolic phenomenon like cerebrovascular disease and infective endocarditis with valvular insufficeincy. The disease activity and titer of the antibodies in Systemic Lupus Erythematosus can be linked to Libman-sack Endocarditis.

HISTORICAL PERSPECTIVES:

Libman and Sack in 1924, first coined this term for the sterile verrucous vegetations of the mitral and aortic valves in patients of Systemic Lupus Erythematosus.
