Abstract
A prosthetic heart valve includes a non-collapsible annular frame extending in a longitudinal direction between an inflow edge and an outflow edge, and a valve assembly connected to the frame. The frame includes a plurality of annularly spaced commissure posts adjacent the outflow edge, each of the commissure posts including a tip and a post slot spaced apart from the tip. The prosthetic heart valve further includes a radiopaque element including an elongated main body having a first end and a second end. The radiopaque element may extend around the tip and through the post slot of at least one of the commissure posts so that a portion of the main body extends between the slot and the tip. Alternatively or additionally, a radiopaque element may be positioned adjacent a base of the frame.
