Successful Medical Treatment of Prosthetic Valve Endocarditis with a Perivalvular Abscess / 日本心臓血管外科学会雑誌

ABSTRACT

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 (11 mm×15 mm). 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.
