[Management of quadruple valves for severe infective endocarditis; report of a case].

A 74-year-old man had pustulant bilateral arthritis complicated with sepsis and disseminated intravascular coagulation (DIC). Microbiologic study of blood sample showed Streptococcus and methicillin resistant Staphylococcus aureus (MRSA). He was complicated with postulant diskitis since then. Medical treatment for DIC and administration of antibiotics were performed. Preoperative echocardiography revealed massive aortic regurgitation and vegetation of aortic valve, moderate pulmonary regurgitation and vegetation of pulmonary valve, massive mitral regurgitation, massive tricuspid regurgitation. He was diagnosed as infective quadruple valve endocarditis. He received aortic valve replacement, pulmonary valve replacement, mitral valve repair and tricuspid valve repair. Postoperative echocardiography showed satisfactory function of bioprosthesis. Postoperative course was uneventful.
