Dual valve prosthesis for transcatheter valve implantation

A method of implanting a dual heart valve prosthesis within a beating heart comprising:

• introducing a delivery catheter into the left ventricle of the heart, wherein a dual heart valve prosthesis having first and second prosthetic heart valve components connected by a linkage is disposed within a distal portion of the delivery catheter, wherein the linkage laterally extends between a downstream end of the first prosthetic heart valve component and an upstream end of the second prosthetic heart valve component;
• deploying the first prosthetic heart valve component within the native mitral valve;
• and
• deploying the second prosthetic heart valve component within the native aortic valve, such that the linkage connecting the first and second prosthetic heart valve components pushes the anterior leaflet of the native mitral valve against the wall of the left ventricle.

A dual heart valve prosthesis comprising:

• a prosthetic mitral valve component for implanting within the native mitral valve having a stent structure with a prosthetic mitral valve secured therein, wherein the stent structure of the prosthetic mitral valve component in an expanded configuration has an upstream segment with a greater expanded diameter than a downstream segment thereof;
• a prosthetic aortic valve component for implanting within the native aortic valve having a stent structure with a prosthetic aortic valve secured therein, wherein the stent structure of the prosthetic aortic valve component in an expanded configuration has a downstream segment with a greater expanded diameter than an upstream segment thereof;
• and
• a linkage that laterally extends between an outflow end of the prosthetic mitral valve component and an inflow end of the prosthetic aortic valve component to connect the respective stent structures together, wherein the linkage is configured for contacting the anterior leaflet of the native mitral valve within the left ventricle when the dual heart valve prosthesis is implanted within the heart.
