Abstract
A method of implanting a prosthetic mitral valve assembly is disclosed. The prosthetic mitral valve assembly includes a stent and valve combination. The prosthetic mitral valve assembly is provided with an anchoring portion adapted to be positioned in the left atrium. In one embodiment, the anchoring portion includes at least one anchoring arm sized for placement in a pulmonary vein. The stent is radially expandable so that it can expand into position against the walls of the left atrium and accommodate a wide range of anatomies. Contact between the stent and the native tissue in the left atrium reduces paravalvular leakage and prevents migration of the stent once in place.
