Heart Valve Involvement (Mitral Valve Regurgitation) Caused by Libman–Sacks Endocarditis in Systemic Lupus Erythematosus : A Case Report and Review of the Literature

Libman–Sacks (LS) endocarditis is one of the most common cardiac manifestations of both systemic lupus erythematosus (SLE) and the antiphospholipid syndrome (APS). We report a case of mitral valve replacement for mitral regurgitation (MR) caused by Libman-Sacks endocarditis in young patient with systemic lupus erythematosus (SLE). In conclusion, Although typically mild and asymptomatic, the disease can lead to serious complications, including superimposed bacterial endocarditis, thromboembolic events, and severe valvular regurgitation and/or stenosis requiring surgery.
