Abstract

Systems and methods for medical interventional procedures, including approaches to valve implantation. In one aspect, the methods and systems involve a modular approach to mitral valve therapy.

Claims

1. A mitral valve replacement system for a heart, the mitral valve including commissural clefts, an anterior leaflet, a posterior leaflet, an annulus and a sub-annular gutter, comprising:

an anchor assembly configured for placement within the heart, the anchor assembly including a retention structure and a plurality of projections, the retention structure being configured so that it resides spaced from to the mitral valve and at least one of the plurality of projections being configured so that the one projection is placed into engagement with the sub-annular gutter; and

an artificial valve configured for engagement with the retention structure of the anchor assembly;

wherein the retention structure of anchor assembly remains spaced from the annulus and the anchor assembly permits maintenance of natural function of anterior and posterior leaflets of the mitral valve until placement of the artificial valve.
