Abstract
A prosthetic heart valve has an annular valve-perimeter-shape-defining structure having a radially outer surface. A clip structure is provided on the outer surface. This clip structure is used to attach flexible valve leaflets to the shape-defining structure. One or more retainer members may be used to help hold the leaflets in the clip structure.
