Mitral valve replacement in systemic lupus erythematosus associated Libman–Sacks endocarditis

Abstract

Libman–Sacks endocarditis, first discovered in 1924, is a cardiac manifestation of systemic lupus erythematosus (SLE). Valvular involvement has been associated with SLE and antiphospholipid syndrome (APS). Mitral valve, especially its posterior leaflet, is most commonly involved.We report a case of a 34year old woman with antiphospholipid antibody syndrome and SLE, who presented with mitral valve regurgitation. The patient underwent a prosthetic mitral valve replacement, with no followup complications.We suggest mechanical valve replacement employment in the management of mitral regurgitation in Libman–Sacks endocarditis, in view of the recent medical literature and our own case report.
