1. A replacement cardiac valve, comprising:
a ventricular portion having a first stiffness, the ventricular portion formed of a super elastic material such that it is configured to self-expand from a collapsed configuration to an expanded configuration, the ventricular portion having a channel configured to receive a wire and extending substantially around a circumference of the ventricular portion, wherein the channel is a tubing and has a first end and a second end and forms a substantially circular shape comprising an incomplete circle having a C-shape defining a gap between the first end and the second end, wherein the channel is positioned on a luminal surface of the ventricular portion; and
the wire configured to be advanced into the channel to increase the first stiffness to a second stiffness.
