Abstract
A stented valve prosthesis for implantation within a native mitral valve having a generally tubular expandable stent structure having a first end, a second end, a central body portion having one or more openings, and a longitudinal axis. A wing portion extends outwardly from the stent structure and away from the longitudinal axis of the stent structure in an expanded deployed configuration. A radius of the wing portion is greater than a radius of the central body portion in the expanded deployed configuration, and the wing portion fits within one of the openings in the central body portion of the stent structure in a crimped delivery configuration. A valve structure having a plurality of leaflets is attached to an interior of the stent structure.
