1. A device for repair or replacement of a native heart valve, the native heart valve having an annulus and leaflets coupled to the annulus, comprising:

  • a valve support having an upstream end and a downstream end extending along a longitudinal axis, the valve support having an outer surface and an inner surface, wherein the inner surface is configured to support a prosthetic valve, and wherein the valve support has a cross-sectional shape;

    an expandable ring-shaped retainer coupled to the upstream end of the valve support, the retainer configured to engage and seal with tissue on or near the annulus on an inner or upstream side of the native leaflets; and

    wherein the valve support is mechanically isolated from the retainer such that the cross-sectional shape of the valve support remains sufficiently stable that the prosthetic valve remains competent when the retainer is deformed in a non-circular shape by engagement with the tissue.
