    摘要： A remodeling mitral annuloplasty ring with a reduced anterior-to-posterior dimension to restore coaptation between the mitral leaflets in mitral valve insufficiency (IMVI). The ring has a generally oval shaped body with a major axis perpendicular to a minor axis, both perpendicular to a blood flow axis. An anterior section lies between anteriolateral and posteriomedial trigones, while a posterior section defines the remaining ring body and is divided into P1, P2, and P3 segments corresponding to the three scallops of the same nomenclature in the posterior leaflet of the mitral valve. The anterior-to-posterior dimension of the ring body is reduced from conventional rings; such as by providing, in atrial plan view, a pulled-in P3 segment. Viewed another way, the convexity of the P3 segment is less pronounced than the convexity of the P1 segment. In addition, the ring body may have a downwardly deflected portion in the posterior section, preferably within the P2 and P3 segments. The downwardly deflected portion may have an apex which is the lowest elevation of the ring body and may be offset with respect to the center of the downwardly deflected portion toward the P1 segment. A sewing cuff may have an enlarged radial dimension of between 5-10 cm, or only a portion of the sewing cuff may be enlarged.

    摘要翻译： 重建二尖瓣瓣环成形术环，具有减小的前后尺寸，以恢复二尖瓣关闭不全（IMVI）中的二尖瓣小叶之间的接合。 环具有大致椭圆形的主体，其长轴垂直于短轴，两者垂直于血流轴线。 前段位于前外侧和后内侧三角形之间，而后段限定剩余的环体，并分为对应于二尖瓣后叶中相同命名的三扇贝的P 1，P 2和P 3段 。 环体的前后尺寸从常规环减少; 例如通过在心房平面图中提供一个拉入的P 3区段。 换句话说，P 3段的凸度比P 1段的凸度更不明显。 此外，环体可以在后部中具有向下偏转的部分，优选地在P 2和P 3段内。 向下偏转的部分可以具有顶点，其是环体的最低高度，并且可以相对于朝向P 1段的向下偏转部分的中心偏移。 缝制袖口可以具有在5-10cm之间的放大的径向尺寸，或者仅可以扩大一部分缝合袖口。

    摘要： The present invention refers to an annular prosthesis for mitral valve. In one of its embodiments the annular prosthesis for mitral valve is made up of a posterior half-ring and an anterior half-ring coupled to each other on a first transverse plane which defines a maximum width section of the prosthesis, characterised in that the ratio between the distance between said anterior half-ring and said posterior half-ring, as measured along a second plane, perpendicular to said first plane and equidistant to said couplings, and said maximum width of the prosthesis is lower than 3/4.
