1. A prosthetic valve for implantation within a native mitral valve, the prosthetic valve comprising:

  • an annular valve body having an upstream end, a downstream end opposite the upstream end, and an intermediate portion extending between the upstream end and the downstream end;

    a plurality of atrial anchoring arms configured to extend from the intermediate portion of the valve body in a generally radially outward direction; and

    a plurality of ventricular anchoring legs configured to extend from the intermediate portion of the valve body in a generally radially outward direction, each ventricular anchoring leg having a proximal end secured to the annular valve body and a terminal end opposite from the proximal end, wherein at least one atrial anchoring arm is configured to extend radially outward beyond the terminal ends of the ventricular anchoring legs,wherein beyond locations of connection to the intermediate portion, the atrial anchoring arms and the ventricular anchoring legs are devoid of lateral interconnections therebetween,wherein the at least one atrial anchoring arm is configured to extend in the generally radially outward direction from a single location of connection to the intermediate portion of the valve body,wherein a proximal portion of at least one ventricular anchoring leg is configured to extend in an upstream direction, the proximal portion including the proximal end of the at least one ventricular anchoring leg, andwherein the annular valve body comprises a strut extending from the location of connection of a first ventricular anchoring leg of the plurality of ventricular anchoring legs, wherein an entire length of the strut is situated midway between two adjacent atrial anchoring arms.
