As reported by our affiliates in (b)(6), the patient who underwent an implant of a 29mm sapien 3 valve, in pulmonic position, by transfemoral approach required a valve in valve procedure due to degeneration of the valve.

As the valve remains implanted, a no product returned engineering evaluation was performed.As the device was not returned, no visual inspection, function testing or dimensional testing could be performed.No imagery was provided for review.Review of the work orders related to the manufacturing of the devices and components that could potentially contribute to the complaint did not reveal any manufacturing non-conformance issues that would have contributed to the complaint event.A review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of the failure mode is not required at this time.Since no product non-conformance were identified, a product risk assessment (pra) escalation is not required.Since no edwards defect was identified, no corrective or preventative actions are required.Device degeneration is a known potential risk associated with the tavr procedure and is listed in the instructions for use (ifu) as a potential adverse event.Structural valve deterioration (svd) may be manifested as stenosis with thickened leaflets.Svd refers to changes intrinsic to the valve, and can include failure modes such as wear, calcification, leaflet tear, stent creep, leaflet disruption, or leaflet retraction.Svd may be mild and not require any intervention or it may be moderate to severe.It can cause the heart to work harder to eject blood from the ventricle.Depending on the severity it could be an indication for valve replacement or medical intervention.Tissue calcification is a very common failure mode.The mechanisms for bioprosthetic heart valve tissue calcification are not fully understood.Many factors can contribute to the onset and propagation of calcification including patient related (e.G.Patient age, disease state, immune status, and other co-morbidities), pharmacological, and intrinsic properties of the valve itself.It is widely understood that patients with chronic renal disease and prior history of calcific stenosis of the native valve may be predisposed to bioprosthetic calcification.In this case, complaint was unable to be confirmed due to device unavailability/imagery unavailability.Based on the limited information provided, the root cause for the valve degeneration approximately 3 years 4 months post valve implant could not be determined but may be related to the patient's co-morbidities and/or progression of the pre-existing valvular disease process (carcinoid syndrome).Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.No corrective or preventative actions are required.

As reported by our affiliates in italy, the patient who underwent an implant of a 29mm sapien 3 valve, in pulmonic position, by transfemoral approach required a valve in valve procedure due to degeneration of the valve.The physician confirmed the cause of the degeneration was regurgitation due to leaflet fibrosis in carcinoid syndrome.
