COLLAPSIBLE VALVE PROSTHESIS |
摘要 |
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.
