Event Description

According to the initial report received via email on 08sept2023, a on-x mitral implant registration card returned from the user facility is for a patient with an existing on-x mitral valve implanted.The artivion field representative replied to the request for additional information as follows "i tried several times to get info on this valve, but never received a response.There was never a complaint from the surgeon or anyone else about this valve." no additional information forthcoming.This investigation is relegated to onxmc-25/33.Serial number: (b)(6).

Manufacturer Narrative

The manufacturing records for serial number (b)(6) were reviewed, and it was confirmed that all records were controlled, available for review, and met all specifications per the device master record.All lots passed functional testing and met release specifications.During the investigation no non-conformances or deviations were noted.Document change orders le17685 and le17849 were issued for leaflet tuning as a part of the standard manufacturing process.On (b)(6) 2021 an onxmc 25/33 sn (b)(6) was used in a case for a 48-year-old male in the mitral position.A second mitral on-x was reported to device tracking as implanted in the same position, same patient: (b)(6) 2023 onxmc 25/33 sn (b)(6) (707 days post-implant).Attempts to receive additional information received no response.Review of manufacturing records show no processing issues.The valve was not returned to the manufacturer for examination.We have no information about the explanted on-x valve other than the tracking notice and assume the valve was discarded on site.Consequently, we do not have enough information to know what, if any, contribution the valve had to the decision to replace it.The instructions for use for the on-x valve lists the possibility of explantation as a consequence of a complication of prosthetic heart valve replacement [ifu].But in this instance, we do not have any information to help us identify that complication.After multiple attempts to obtain additional information, we completed this report with the limited available information.As such the determination was made that there is not enough information to determine what, if any, contribution the on-x valve had to the decision for its removal.There is not sufficient data to determine a failure mode; thus, severity and occurrence is not evaluated.No further action is required without additional information.The root cause is unknown.After multiple attempts to obtain additional information, we completed this report with the limited available information.As such the determination was made that there is not enough information to determine what, if any, contribution the on-x valve had to the decision for its removal.This event does not identify additional hazards or modify the probability and severity of existing hazards, and the ifu adequately communicates risk.This complaint was reviewed for a capa evaluation and a capa is not warranted.Field assurance will continue to monitor similar complaints to determine if additional actions are warranted; however, at this time no further actions are necessary.This report is being submitted as required by federal regulations and does not constitute an admission that the device caused or contributed to the reported event.Furthermore, this report reflects the event as alleged by the complainant and does not imply that the information reported to artivion is accurate or has been confirmed by artivion.
