A stentless bioprosthetic graft for repairing a first native heart valve and a second native heart valve in a heart. The bioprosthetic graft includes a harvested homograft having a harvested mitral valve portion, a harvested distal aorta, and an extension portion made of a biocompatible material. The harvested distal aorta further includes a harvested aortic valve, a harvested aortic root, and at least a portion of a harvested atrial wall. The harvested mitral valve portion is for suturing place of the first native heart valve, and the harvested distal aorta is for suturing to a partial section of the second native heart valve. The extension portion is sutured to the homograft and is for suturing to the left atrial wall of the heart to close an incision in the left atrial wall following implantation of the harvested mitral valve portion and the harvested distal aorta of the homograft.
