Claim 0:
1. A replacement heart valve configured to collapse radially to a collapsed configuration for delivery within a delivery device and expand radially to an expanded configuration configured to engage a native mitral valve annulus upon being released from the delivery device, the replacement heart valve comprising:
a self-expanding frame, the frame comprising:
an upstream end comprising a plurality of struts;
a downstream end comprising a plurality of downstream anchors that extend upward toward the upstream end when the replacement heart valve is in the expanded configuration, the downstream anchors being configured to grasp the native mitral valve annulus when the replacement heart valve is in the expanded configuration; and
a transition portion positioned between the upstream end and the downstream end of the frame;

a valve skirt attached to the frame and extending from the upstream end of the frame to the downstream end of the frame; and
a valve body comprising a plurality of valve leaflets, wherein each of the valve leaflets extends between a fixed proximal edge and a free distal edge, the free distal edges of the valve leaflets configured to open together to allow flow in a first direction from the upstream end of the frame to the downstream end of the frame and configured to alternatively close together to prevent flow in a second direction from the downstream end of the frame to the upstream end of the frame,
wherein the valve leaflets include two commissural tabs on opposing sides of the valve leaflets,
wherein the plurality of valve leaflets are attached to the valve skirt,
wherein each of the plurality of downstream anchors comprises an enlarged tip,
wherein the replacement heart valve is a replacement mitral valve,
wherein, when the replacement heart valve is in the expanded configuration, a downstream end of the valve skirt is configured to contact native leaflets of the native mitral valve annulus to reduce the likelihood of blood leakage between the replacement mitral valve and the native mitral valve annulus, and
wherein the frame comprises a plurality of connector eyelets configured to receive a tether.
