Manufacturer Narrative

Investigation is not yet complete.A follow-up report will be submitted with all additional relevant information.

Event Description

It was reported that on (b)(6) 2023, a 23mm sjm regent heart valve was chosen for implant.After the valve was sutured in place, the valve was rotated using the holder handle while inserted into the orifice at a 90 degree angle.The valve was in the closed position when it was rotated.The physician felt resistance while rotating the valve, and the leaflets fractured into multiple pieces.It was reported all pieces were recovered from the patient.There was no report of any instruments that encountered the valve at the time of fracture, only the holder handle was used to rotate the valve.A decision was made explant the device and replace it with a 21mm sjm regent heart valve.The patient remained hemodynamically stable throughout the procedure.There was no clinically significant delay in procedure and no adverse patient effects.The patient status was reported as stable.

Manufacturer Narrative

An event of the valve fracturing while it was being rotated was reported.The investigation confirmed that the orifice had fractured in three places and that the leaflets had dislodged.The dislodged leaflets were not fractured.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications.Information from the field indicated that some resistance was felt while rotating the valve.Per the instructions for use, "using the valve holder/rotator and the flexible valve holder handle model 905-hh, or the rigid valve holder handle model 905-rhh, rotate the valve in situ to the desired position.The valve should rotate freely.If resistance is noted, the valve holder/rotator may not be properly seated in the valve, the valve may not be in the fully closed position, or the valve may be oversized.If the valve does not rotate freely, do not force valve rotation.".In this case, a smaller valve was successfully implanted after the fractured valve was removed, and oversizing of the valve and rotation of the valve in spite of the resistance being felt could have contributed to the reported event.There is no indication of a product quality issue with regards to manufacture, design, or labeling.
