[Longitudinal Direct Closure of Mitral Anterior Leaflet Large Perforation for Infective Endocarditis:Report of a Case].

A 65-year-old man was presented with infective endocarditis of mitral valve. Echocardiography revealed severe mitral regurgitation and moderate aortic regurgitation. The aortic regurgitant jet directed toward the mitral anterior leaflet, so thickening and perforation of the anterior leaflet of the mitral valve were observed. In addition, Staphylococcus epidermidis was detected in blood culture. After infection control, aortic valve replacement and mitral valve repair was performed. A 17 mm diam-eter perforation of the anterior mitral leaflet were closed directly and longitudinally with 5-0 prolene polypropylene suture and mitral valve regurgitation was controlled. Primary closure was simple and effective for anterior mitral leaflet perforation.
