Added information to d4, h4, h6.The device history record 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.Tissue degeneration-related structural deterioration, either calcific or non-calcific, are common chronic failure modes for this type of bioprosthetic heart valve.Operational mechanical stress and biological factors are generally believed to be the major contributors to the non-calcific bioprosthetic tissue degeneration.Structural valve deterioration (svd) can, and typically does, lead to chronic central leaks over a period of time.Svd is the most common reason for bioprosthesis explant and encompasses multiple failure modes, including calcification, non-calcific degeneration, dehiscence, cusp thickening or fibrosis, or a combination of these.Such failure modes may occur singularly or concomitantly.Degeneration-related structural deterioration is most commonly related to patient factors and is not usually an indication of a device malfunction related to a manufacturing deficiency.Patient prosthesis mismatch (ppm) is present when the effective orifice area of the inserted prosthetic valve is too small in relation to body size.Its main hemodynamic consequence is to generate higher than expected gradients through a normally functioning prosthetic valve.A definitive root cause cannot be conclusively determined; however, patient factors likely caused or contributed.

The device was not returned to edwards for evaluation as it remains implanted.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 events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

It was reported a patient with a 21mm 3000tfx aortic valve implanted eight (8) years, seven (7) months, is being evaluated for valve-in-valve procedure due to degeneration, stenosis, and patient prosthesis mismatch.Patient presented with shortness of breath and fatigue.Physician team in discussion whether to proceed with tavr and savr.
