1. A valve prosthesis configured for percutaneous deployment at a mitral valve in the heart, the prosthesis comprising:

  • a support structure configured to support a prosthetic heart valve, wherein the support structure has a stent framework having an upstream section with a greater expanded diameter than a downstream section, and defining a plurality of continuous regions and a plurality of discontinuous regions that alternate with one another around a circumference of the stent framework,wherein each of the continuous regions of the stent framework forms a longitudinally extending band of cells that are connected to each other from an upstream end to a downstream end of the stent framework, and wherein each of the discontinuous regions of the stent framework forms a longitudinally extending band of cells from the upstream end to the downstream end of the stent framework with neighboring cells between the upstream and downstream sections being unconnected from one and other, andwherein within each of the discontinuous regions of the stent framework the unconnected cell of the downstream section at least partially overlaps with the unconnected cell of the upstream section by longitudinally extending within the upstream section of the stent framework such that the unconnected cell of the downstream section is positioned radially inward of the unconnected cell of the upstream section.
