Stented heart valve devices

A valve prosthesis comprising:

• a stent frame comprising:
• an annular portion comprising:
• a longitudinal axis,
• at least two extending posts, and
• a generally sinusoidal structure of peaks and valleys between each of the at least two extending posts, the generally sinusoidal structure having first and second ends,
• wherein the generally sinusoidal structure has a generally constant height and
• wherein, in an expanded state, each of the extending posts extends in a direction that is generally parallel to the longitudinal axis and has a height that is greater than the generally constant height between each of the extending posts of the generally sinusoidal structure of the annular portion;
• an atrial portion extending from the first end of the generally sinusoidal structure, wherein the atrial portion comprises:
• a plurality of flares that extend radially outward relative to the longitudinal axis of the annular portion as the plurality of flares extend away from the annular portion, and
• a dome-type structure extending from the plurality of flares;
• a ventricular portion extending from the second end of the generally sinusoidal structure, wherein the ventricular portion comprises:
• at least one flare that extends radially outward relative to the longitudinal axis of the annular portion, and
• a first portion that extends from the second end of the generally sinusoidal structure, the first portion having a height that is smaller than a height of the at least one flare of the ventricular portion;
• and
• a prosthetic valve comprising a first leaflet attached to two adjacent extending posts of the at least two extending posts within an interior area of the stent frame, and a second leaflet attached to two adjacent extending posts of the least two extending posts within the interior area of the stent frame,
• wherein the extending posts of the annular portion are aligned with commissures of the prosthetic valve.
