Isolated Tricuspid Valve Libman-sacks Endocarditis in Patient with Systemic Lupus Erythematosus: A Rare Case Report and Literatures Review

Libman-Sacks endocarditis (LSE), characterized by the formation of verrucous vegetations, is a typical cardiac manifestation of autoimmune diseases such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). It primarily leads to cardiac valve lesions. The most commonly affected valves in systemic lupus erythematosus are the mitral and aortic valves. Although isolated tricuspid valve involvement is quite rare. Here, we report the case of a 38-year old female with a history of SLE who suffered from acute right heart failure caused by tricuspid vegetation and valve regurgitation. The patient was successfully treated with prednisolone and hydroxychloroquine, and follow-up echocardiography showed the disappearance of the vegetations.
