Abstract: A collapsible valve prosthesis includes an armature and a set of prosthetic valve leaflets supported by the armature. The armature is expandable from a contracted condition to an expanded condition for anchoring at an annulus of a natural valve site, and includes a tubular intra-annular portion defining a blood flow lumen having an inflow side and an outflow side. The tubular intra-annular portion supports the prosthetic valve leaflets in the blood flow lumen and is provided with outward formations for coupling with the natural valve site. The armature includes an over-annular portion linked to the intra-annular portion to extend collar-like over the annulus of the natural valve site at the inflow side of the blood flow lumen. The armature may also include an under-annular portion to extend collar-like at the outflow side of the blood flow lumen. The prosthesis may permit mitral valve replacement (MVR) without removing the native valve leaflets and the chordae tendineae.

Abstract translation: 可折叠瓣膜假体包括电枢和由电枢支撑的一组假体瓣膜小叶。 电枢从收缩状态膨胀到膨胀状态，用于锚定在自然阀位的环状部，并且包括限定具有流入侧和流出侧的血流腔的管状环状内部。 管状环形内部部分支撑血流腔中的假体瓣膜小叶，并且设置有用于与天然瓣膜部位联接的向外构造。 电枢包括连接到内环形部分的过环形部分，以在血流腔的流入侧处在自然瓣膜部位的环上延伸颈圈状。 电枢还可以包括在血流腔的流出侧处延伸环状的下环形部分。 假体可以允许二尖瓣置换（MVR），而不需要去除天然瓣叶和腱索。
