Device is not accessible for testing as it remained implanted in the patient.The review of historical data indicated that no other similar complaint was reported for the same lot number.A review of the complaint device history records is ongoing, results are pending.The investigation is still ongoing.A follow-up report will be sent upon completion of the investigation.

Manufacturer Narrative

(11/3221) a first retention sample from the same sterilization lot and from the same product family, coated one day after and under similar conditions as the involved device underwent water permeability testing.However, according to the qa manager, the water permeability result on the retention product is not admissible due to the degraded condition of the retention product and its over-handling prior to the test.This result should not be considered in this investigation.(3331- 4110/213) additional production records and trend analyses were performed by the qa manager following the retention sample analysis.The traceability analysis did not show any specific items.(b)(4).The search shows no similar complaints on lots 22c10, 22c17, 22c24, 22c31 and 22d07.There is no trend on cardioroot products.The qa manager did a review of the investigation at the time and concluded that: "based on all the above, no anomalies/trends were found that could direct the investigation to a production problem.[.] the investigation is currently directed towards an isolated case." (4102/213) a second retention sample was selected by the qa manager.The sample is from another sterilization lot and has more parameters in common (collagen dispersion and date of quality control) than the product already tested (apart from product type).This second retention sample underwent waterpermeability testing.The test result is 0.48 ml/cm²/min which is within specification (< 5 ml/cm²/min).(11) the investigation is still ongoing.A follow-up report will be sent upon completion of the investigation.

Manufacturer Narrative

(4112/213) the case description and the investigation has been reviewed by the medical affairs manager whose assessment is below: "the complaint recorded describes a procedure where a 30 mm cardioroot graft was sutured to a 27mm edwards inspiris valve using 6-0 prolene suture, then implanted using a continuous prolene suture.No additional procedural details were provided.The following day, the patient returned to the or to achieve ¿hemostasis¿.It was reported that the surgeon used the cardioroot graft once previously.The account was contacted for additional information regarding details of the procedure, however no information was provided.It would be important to understand where the issue of ¿hemostasis¿ (i.E.Bleeding) was seen when the patient underwent reoperation, if the post-op coagulation parameters were normal, and what exactly was done to repair the issue.Additionally, there was no mention of any intraoperative challenges, such as a complicated procedure, friable tissue, or difficult anatomy which may have contributed to bleeding issue.The customer suggested that when using cardioroot, he may ¿adapt his technique by including haemostatic agents and possibly mattress sutures with pledgets.¿ because the cardioroot graft remained implanted, retention product was tested for water permeability.The first test was deemed not acceptable due to the condition of the product and its over-handling before the test.This result was not taken into account in the investigation.The second retention sample,which came from a different lot resulted in conformance to the specifications.There is a second complaint for the same lot number however, it is not similar in nature as the complaint was regarding "damaged packaging during handling" and no issue with bleeding was noted.In conclusion, based on the extremely limited information provided in this complaint record and without knowing the surgical details regarding the implantation of the cardiorootvascular graft and edwards valve, it is difficult to ascertain the exact cause of the hemostasis issue.Considering that the graft remained implanted and it is unknown exactly what caused the bleeding issue or how the issue was resolved, as well as the surgeon¿s lack of experience with the cardioroot graft, it is reasonable to conclude that the bleeding was not likely due to the cardioroot graft itself, but perhaps with one of the above mentioned contributing factors." (67) no conclusion can be drawn since the product remained implanted.However, the conducted investigation and testing performed suggest that the product was not defective at the time of manufacturing.(22) please note that blood leakage is an undesirable side-effect as indicated in the instructions for use.
