Prosthetic heart valve

A prosthetic heart valve, comprising:

• a support structure, wherein the support structure defines an elongate central passageway, wherein the support structure comprises an one or more atrial arms, a one or more ventricular arms, and a third set of arms;
• a plurality of leaflet elements attached to the support structure and disposed within the elongate central passageway for control of blood flow through the elongate central passageway;
• a cover formed separately from the support structure and supported by the third set of arms, the cover configured to contact a native leaflet and reduce leakage around the prosthetic heart valve,
• wherein the support structure is configured to biodynamically fix the prosthetic heart valve to native leaflets of a native heart valve of a heart and is not fixed to the native annulus of the heart valve, and
• wherein the one or more atrial arms and the one or more ventricular arms extend across a cross-sectional plane of the cylindrical portion of the support structure such that:
• 1) a distal segment of the one or more atrial arms extend perpendicularly away from a central axis of the elongate central passageway and contact the native leaflets on the atrial side of the native heart valve;
• and/or
• 2) a distal segment of the one or more ventricular arms extend perpendicularly away from the central axis of the elongate central passageway and extend toward the atrial end of the cylindrical portion of the at least one support structure, thereby enabling the distal segment of the one or more ventricular arms to contact the native leaflets on the ventricular side of the native heart valve.
