Abstract
A prosthetic heart valve includes a non-collapsible annular frame extending between an inflow edge and an outflow edge, the frame having a plurality of annularly spaced commissure posts adjacent the outflow edge. A valve assembly including a plurality of leaflets is connected to the frame. The frame includes a weakened portion such that the frame is expandable from an initial condition having a first diameter to an expanded condition having a second diameter larger than the first diameter when a radially outward force is applied to an inner surface of the frame. A stabilizing strut may be positioned adjacent the weakened portion to reinforce the frame. The prosthetic heart valve may include an expandable ring positioned around the expandable frame.
