Event or Problem Description
Medtronic received information that during the implant of this 23mm aortic bioprosthetic valve, it was explanted and replaced with a 21mm valve of the same model.The reason for the replacement was reported as sizing issues.It was further noted that a 23mm sizer was used for annulus sizing, and no apparent resistance was observed as the process was smooth and uneventful.During implant, the 23mm valve could not be implanted despite multiple attempts.It was then decided to implant a 21mm valve instead.No additional adverse patient effects were reported.
