[Aortic valve replacement due to Libman-Sacks endocarditis combined with infectious endocarditis].

A 40-year-old female had a history of fever, arthralgia, proteinuria, and dyspnea on effort twenty years ago, and was diagnosed as SLE, renal failure, and aortic regurgitation. She also suffered from pyelonephritis and sepsis due to the infection of E. coli. Preoperative examination revealed non-active phase of SLE. Echocardiography and aortography showed massive aortic regurgitation and operation was recommended. Operative findings showed fresh vegetation on the aortic leaflets, and aortic valve replacement (Tekna-Edwards 19 mm) was performed. Histological findings of the vegetation showed Libman-Sacks endocarditis and infectious endocarditis. Predonisolone was infused intravenously to prevent the acute deterioration of SLE after the operation. She was discharged from the hospital three weeks after the operation.
