1. A compressible and expandable stent assembly for implantation in a body lumen, the stent assembly comprising:
- a first stent comprising a first length that extends along a first longitudinal axis and a tubular structure that is compressible and expandable in a radial direction;
a second stent comprising a second length that extends along a second longitudinal axis that is less than the first length and a tubular structure that is compressible and expandable in a radial direction, wherein the first longitudinal axis is parallel to the second longitudinal axis, wherein the second stent is coupled adjacent to and extends from the first stent along a tangential line that extends in a parallel direction to the first and second longitudinal axes and in a perpendicular direction to the radial expansion direction of the first and second stents;
a first prosthetic valve disposed within the first stent; and
a second prosthetic valve disposed within the second stent.

Abstract
A compressible and expandable stent assembly for implantation in a body lumen such as a mitral valve, the stent assembly including at least one stent barrel that is shaped and sized so that it allows for normal operation of adjacent heart structures. One or more stent barrels can be included in the stent assembly, where one or more of the stent barrels can include a cylinder with tapered edge.
