Manufacturer Narrative

The subject device is not available for evaluation because it was sent to hospital pathology.The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.Edwards will continue to review and monitor all reported events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Event Description

Edwards lifesciences maintains an implant patient registry (ipr).This registry is a patient tracking mechanism for serialized edwards implantable devices (bioprosthetic heart valves and annuloplasty rings), rather than a true post-market surveillance registry.Through the registry, edwards is notified when these devices are implanted.In addition, patient and/or device status may be reported to the registry via the implantation data cards.The information is received from various sources (e.G.Surgeon, hospital, and patient family members) and is not received in the form of a conventional "customer complaint".The information reported may or may not be related to the edwards device.It was reported via the implant patient registry that this valve model 6900p31c implanted in mitral position was explanted from a 66 year old patient after an implant duration of nine (9) years and two (2) months due to calcification and leaflet thickening leading to stenosis.The patient presented with hear failure.A valve model 11400m31mm was implanted in replacement.The patient was noted as to be discharged home.

Manufacturer Narrative

Updated section b4 (date of this report), g3 (date received by manufacturer), h6 (device code) and h6 (health effect - impact code).H10: additional manufacturer narrative: images were reviewed.Pictures showed an explanted valve with blood residues.Customer report of calcification, leaflet thickening leading to stenosis cannot be confirmed through visual observation.In one of the pictures, host tissue seemed to be observed on one of the leaflets at the inflow aspect.

Manufacturer Narrative

The device history record (dhr) was reviewed and shows that this device met all manufacturing specifications for product release prior to distribution.No issues were identified that would have impacted this event.Calcific degeneration is a common cause of bioprosthetic heart valve failures.Many factors contribute to the onset and propagation of calcification.These include patient factors (age, disease state, pharmacological intervention, etc.), mechanical stress related to the valve's hemodynamic performance, and glutaraldehyde fixation of tissue.Of these, the fixation process is a relatively minor contributor to calcification for edwards' tissue valves due to anti-calcification treatments during manufacturing.Though numerous studies have been conducted on preventive calcification strategies in bioprosthetic heart valves, the causes of calcification are not fully understood and there are still no mechanisms or medical therapies which fully prevent bioprostheses from calcifying.Calcification is most commonly related to patient factors and is not usually an indication of a device malfunction related to a manufacturing deficiency.The instructions for use (ifu) have been reviewed and no inadequacies have been identified with regard to warnings, contraindications, and the directions/conditions for the successful use of the device.The reported type of event is included in the ifu.The most likely cause is patient factors, including a history of diabetes.Pannus overgrowth, or host tissue, is considered a form of non-structural valve dysfunction.The growth of host tissue on the sewing ring is expected and is a natural part of the healing reaction to prosthesis implantation.In contrast, if there is an excessive amount of pannus growth, it can extend onto the cusp surfaces leading to thickening of the cusps, leaflet immobility, elevated gradients, and stenosis.Host tissue growth can also contribute to cusp retraction, or curling, resulting in valvular regurgitation.Host fibrous (pannus) tissue growth is not a malfunction of the device related to a manufacturing deficiency.The instructions for use (ifu) have been reviewed and no inadequacies have been identified with regard to warnings, contraindications, and the directions/conditions for the successful use of the device.The reported type of event is included in the ifu.The most likely cause is patient factors.
