Abstract
A dual valve prosthesis having first and second prosthetic valve sections is disclosed. The first prosthetic valve section includes a stent structure with a first prosthetic valve secured therein and the second prosthetic valve section includes an annular frame with a second prosthetic valve secured therein. When the dual valve prosthesis is in an expanded configuration, the annular frame extends from the stent structure such that the first and second prosthetic valves are laterally offset from each other. In a method in accordance herewith, the first and second prosthetic valve sections include prosthetic aortic and mitral valves, respectively, and the dual heart valve prosthesis is configured to replace both the native aortic and mitral valves of the heart in a single transcatheter heart valve implantation procedure.
