1. An implantable prosthetic valve assembly comprising:
- a radially expandable frame comprising,an inflow portion that is configured, in an expanded state, to bear against a native cardiac annulus in a manner so as to resist migration,a second portion extending from the inflow portion in an outflow direction, and configured, in an expanded state, not to bear against the native cardiac annulus and an ascending aorta,an outflow portion extending from the second portion in the outflow direction, and configured, in an expanded state, to bear against the ascending aorta above a coronary ostia, anda plurality of connection rods extending between the second portion and the outflow portion, wherein in an expanded state the plurality of connection rods are arranged uniformly on a periphery of the frame; and
a prosthetic valve coupled to the frame substantially within the second portion.

Abstract
An implantable prosthetic valve assembly includes a radially expandable frame including an inflow portion and a second portion. The inflow portion is configured, in an expanded state, to bear against a native cardiac annulus in a manner so as to resist migration. The second portion extends from the inflow zone in an outflow direction, and is configured, in an expanded state, not to bear against the native cardiac annulus and an ascending aorta. The valve assembly also includes a prosthetic valve coupled to the frame substantially within the second portion.

4. An implantable prosthetic valve assembly comprising:
-
a radially expandable frame comprising, an inflow portion that is configured, in an expanded state, to bear against a native cardiac annulus in a manner so as to resist migration, a second portion extending from the inflow portion in an outflow direction, and configured, in an expanded state, not to bear against the native cardiac annulus and an ascending aorta, wherein the second portion comprises a strut; and a prosthetic valve coupled to the frame substantially within the second portion, wherein the prosthetic valve defines a passage, wherein the prosthetic valve is axially movable with respect to the frame between a non-implantation position outside the second portion and an implantation position that occurs after expansion of the frame, in which the prosthetic valve is immobilized axially with respect to the frame, and wherein the strut slides through the passage as the prosthetic valve moves from the non-implantation position to the implantation position. - View Dependent Claims (5, 6, 17, 18)
