摘要
A 55-year-old male with an intermittent high-grade fever was diagnosed with infective endocarditis. He was indicated for surgery because periodic echocardiography revealed worsening mitral regurgitation and growing vegetation despite medication. An aneurysm of the P2 portion and all vegetations were removed via quadrangular resection of the P2 leaflet, and then the defect was repaired. An intraoperative assessment identified Staphylococcus lugdunensis as the causative bacterium. After postoperative antibiotic therapy for 5 weeks, the patient was discharged without either mitral regurgitation or signs of infection. Infective endocarditis caused by aggressive and destructive S. lugdunensis should be promptly and accurately treated via a surgical approach that prevents progressive tissue destruction and simplifies the surgical procedure for repair, rather than replacement.
