A Case of Infective Endocarditis and Osteomyelitis / 日本心臓血管外科学会雑誌

ABSTRACT

A 53-year-old man was admitted to Jichi Medical School Hospital because of low back pain and respiratory distress. Echocardiography revealed mitral valve regurgitation and mitral vegetations, and MR imaging showed destructive change in the lumbar vertebrae. The low back pain and inflammatory activity subsided with administration of antibiotics, but regurgitation-induced heart failure was medically intractable. The patient underwent mitral valve replacement with a bicarbon valve. The mitral valve showed destructive change with infective vegetation. Microbiologic study of preoperative blood samples and resected valve did not show any organism. Antibiotics were given for another 6 weeks. As of the last follow-up observation at 18 months, the patient was doing well.
