[Mitral valve repair of valve insuffficiency with broad and complex lesions due to infective endocarditis; report of a case].
Surgical intervention is necessary for the treatment of infective endocarditis, although antibiotic therapy has been shown to be effective for treatment of this disorder. Mitral valve infective endocarditis frequently presents with broad and complex lesions, and thus a variety of valve repair is needed. A 40-year-old woman with mitral valve insufficiency due to infective endocarditis underwent mitral valve repair. During the operation, torn chordae, aneurysm with perforation of the anterior leaflet, and torn chordae of the posterior leaflet were found. The chordae of the anterior leaflet were reconstructed and the aneurysm was excised, and autopericardial patch repair was performed. Then, resection and suturing of the prolapsing lesion of posterior leaflet were performed. Mitral valve repair preserves the left ventricular apparatus and function. Therefore, mitral repair results in better prognosis than valve replacement. The repair of the mitral valve should be attempted for the treatment of valve insufficiency due to infective endocarditis.
