Prosthetic valve holder
Single-use handle/holder that ships pre-attached to every mechanical or biological prosthetic valve; grips the sewing ring or commissure posts so the surgeon can position, orient, and rotate the valve into the annulus, then detaches just before the final suture is tightened.
How it is used
Used in every valve replacement (mitral, aortic, or tricuspid).
Clinical tip
Real regulatory alerts document rare cases worldwide of bileaflet mechanical valves being implanted upside-down due to incorrect holder reattachment; manufacturers explicitly warn never to re-attach a valve to its holder once separated.
