According to the initial report received, study patient experienced pericardial effusion and cardiac tamponade, which required reoperation on (b)(6) 2022, 7-days following implant with the device.

The manufacturing records 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 found to be related to the complaint.Device was implanted on (b)(6) 2022 to treat a type a thoracic aortic aneurysm without rupture in a subject of unknown age and sex.The subject was enrolled in study.On (b)(6) 2022 (7 days post implant), the subject underwent reoperation described as a ¿mediastinal revision performed due to significant periaortic hematoma with left plural and pericardial effusion.¿ on (b)(6) 2022, 2 units of prbc¿s were transfused and the subject was diagnosed with acute respiratory failure secondary to recurrence of bilateral pleural effusion in the context of possible post-surgical pleuropericarditis (elevation of apr, persistent low-grade fever, negative cultures).On (b)(6) 2022, a left evacuation thoracentesis was performed, removing 1000ml of serous fluid.The outcome was recorded as ¿symptoms resolved without sequelae¿.As the event of tamponade and pericardial effusion happened 7 days post-implant, this would not be a spontaneous bleeding event due to the valve or anticoagulation therapy, but more likely a sequela of the trauma of surgery and therefore not a reportable bleeding event under the definition of akins, et al.[akins 2008].It is reported here only for the purpose of consistency in documenting adverse events made known to the manufacturer and does not qualify as a bleeding event for comparison to the historical record of valve performance.Pericardial effusion and tamponade caused by fluid accumulation is most likely a consequence of a leaking suture line and is not likely related to the performance of the on-x valve itself.As the anticoagulation status is unknown, we cannot rule out an elevated inr as an exacerbating the event.The risk management and usability engineering file was reviewed and thoroughly identifies the process and product hazards for approved indications.Each individual hazard is mitigated and reduced as far as possible by design and process.Post production residual risk is communicated in the product¿s labeling and ifu (instructions for use).No new risks were identified.References: akins cw, et al.Guidelines for reporting mortality and morbidity after cardiac valve interventions, j thorac cardiovasc surg 2008;135:732-738.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- formerly cryolife/jotec is accurate or has been confirmed by artivion.
