    Abstract:
    A case of perforated mitral valve aneurysm following aortic valve replacement associated with infective endocarditis was reported. The patient was a 29-year-old man, who was suffering from high fever, Osler's nodules and headache. A brain abscess was recognized in a computed tomography and 3rd grade aortic regurgitation was recognized in echocardiogram and aortography. Hematological studies suggested the inflammation and gram-positive cocci was incubated from his arterial blood. Then infective endocarditis with aortic regurgitation was diagnosed. AVR was performed following 8 weeks treatment with antibiotics, when he had negative CRP and his blood culture. After the operation, he was received the intravenous antibiotic therapy for 6 weeks and oral antibiotic drugs was given following his hospital discharge. At 6 months after AVR, mitral valve aneurysm was recognized in his echocardiogram. At 30 months after AVR, the perforation of it was revealed and mitral valve replacement was performed with his negative blood culture. The patient was discharged 28th day after MVR. There has been no active inflammation from his first hospital discharge and following days, the mitral valve aneurysm and the perforation was caused by weakened tissue of the anterior mitral leaflet due to sibilant inflammatory change.
