Libman-Sacks endocarditis (LSE), characterized by verrucous vegetations formation, is a typical cardiac manifestation of autoimmune diseases such as systemic lupus erythematosus (SLE) and antiphospholipid syndrome (APS). It primarily leads to lesions of cardiac valves and mostly involved valves are mitral and aortic, but isolated tricuspid valve involvement is exceptional. Here we reported a 20-years-old female with past SLE history suffered from acute right heart failure caused by multiple tricuspid vegetations and valve regurgitation. The patient recovered following tricuspid valve replacement with a bioprosthesis. Transesophageal echocardiography(TEE), especially real time 3-dimensional (RT3D) TEE provide a better imaging modality for assessing cardiac valvular involvement of LSE. For patients with active SLE/APS course, uncontrolled systemic inflammation may made it difficult for surgical exposure and suture. The durability of bioprosthesis for this patient and the prosthesis selection for tricuspid LSE both need further follow-up and more clinical investigation.
