An apparatus for repairing the function of a native aortic valve, defining a native valve annulus, of a patient includes a tubular valve support member having oppositely disposed first and second valve member ends and a valve member body located between the first and second valve member ends. The valve support member defines a longitudinal axis. A prosthetic valve has at least two prosthetic valve leaflets that are coaptable to permit the unidirectional flow of blood. The prosthetic valve is attached to the valve support member adjacent the second valve member end. At least two coronary openings in the valve member body are located longitudinally adjacent free edges of the at least two prosthetic valve leaflets. At least one of the coronary openings is located so as to be selectively radially aligned with a coronary ostium when the prosthetic valve is located substantially within the native valve annulus. At least two branch support members are provided, with each branch support member having first and second branch ends. Each first branch end is attachable to a coronary opening with the second branch end extending radially away from the valve support member and through a coronary ostium. |
