Summary:Reconstruction of mitral valve, which was performed completely, provides better postoperative ventricular function and less morbidity compared with prosthetic replacement. In this article, reconstructive techniques as a radical mitral valve repair are demonstrated from a viewpoint of long-term performance. Since January, pure mitral regurgitation due to prolapse were repaired with freedom from reoperation of 89% at 5 years and 81% at 10 years. The incidence rate of thromboembolism was 0.8% and no endocarditis or hemorrhagic complications were noted. The technique of leaflet resection-suture is most useful and reliable for the mural leaflet prolapse, and replacement of chordae tendineae is appropriate for the diffuse anterior leaflet prolapse. Prosthetic ring implantation increase leaflet coaptation, reinforce sutures and prevent further annular dilatation.
