A 68-year-old man visited our hospital with a high fever with chills 4 years after aortic valve replacement. Streptococcal species were cultured with a venous blood culture. An echocardiogram and a cardiac computed tomography（CT）scan revealed a perivalvular abscess（11mm×15mm). Because his prosthetic valve functioned well, he was treated with intravenous ampicillin and gentamicin. Cardiac CT scan performed at 6 weeks showed the perivalvular abscess to have disappeared and he was discharged from the hospital. He is free from recurrence of the abscess 20 months after the initiation of therapy.
