Effective reduction of a giant left atrium by partial autotransplantation

Although many surgical procedures have been proposed to reduce the size of a left atrium, their effectiveness is not well established. We present a case of mitral and tricuspid valve insufficiency with a giant left atrium. Partial heart autotransplantation was used in a mitral and tricuspid valve operation with a successful outcome. This procedure can be an effective method to treat giant left atrium.
