Abstract
A hybrid prosthetic heart valve configured to replace a native heart valve and having a support frame configured to be expanded post implant in order to receive and/or support an expandable prosthetic heart valve therein (a valve-in-valve procedure). The prosthetic heart valve may be configured to have a generally rigid and/or expansion-resistant configuration when initially implanted to replace a native valve (or other prosthetic heart valve), but to assume a generally expanded form when subjected to an outward force such as that provided by a dilation balloon or other mechanical expander. An inflow stent frame is expandable for anchoring the valve in place, and may have an outflow end that is collapsible for delivery and expandable post-implant to facilitate a valve-in-valve procedure.
