1. An expandable prosthetic valve configured for implantation within a native heart valve, the prosthetic valve comprising:
an expandable annular valve body;
a plurality of ventricular anchoring legs, each ventricular anchoring leg configured to extend radially outward from the expandable annular valve body to a respective terminal leg end; and
a plurality of atrial anchoring arms, each atrial anchoring arm configured to extend radially outward from a respective proximal arm end secured to the expandable annular valve body to a respective terminal arm end,
wherein the expandable prosthetic valve is configured to assume:
a radially compressed state in which the prosthetic valve is configured to be contained at least partially within a prosthetic valve delivery device, and
a radially expanded state in which the expandable prosthetic valve is configured to be anchored within the native heart valve,
wherein at least one atrial anchoring arm includes:
a rigid portion comprising a strut configured to extend in an upstream direction from the proximal arm end of the at least one atrial anchoring arm, and
a flexible portion comprising a structure with multiple curves and being positioned between the rigid portion and the terminal arm end of the at least one atrial anchoring arm, a proximal section of the structure with multiple curves being situated adjacent to the rigid portion of the at least one atrial anchoring arm, wherein at least the proximal section of the structure with multiple curves has a smaller cross-sectional area than the strut of the rigid portion such that the flexible portion is configured for greater flexibility than the rigid portion, and
wherein when the expandable prosthetic valve is in the radially expanded state, the at least one atrial anchoring arm and at least one ventricular anchoring leg are configured to be arranged such that the proximal section of the structure with multiple curves of the at least one atrial anchoring arm and the terminal leg end of the at least one ventricular anchoring leg are substantially equidistant from a longitudinal axis extending through the center of the annular valve body.
