Leaflet tears occurring over time are a form of structural valve deterioration that may ultimately result in significant regurgitation requiring replacement of the valve.In this case, the explanted device was not returned to edwards for analysis because it was discarded at the hospital.Without return of the device, edwards is unable to conclusively determine the root cause for this event, or confirm the clinical observation.However, advances in valve design and bioprosthetic material have been made with the intention of reducing regurgitation by providing more efficient hemodynamics and longer tissue durability.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Edwards received information that this bioprosthetic aortic heart valve was explanted after fifteen (15) years, two (2) months due to aortic valve insufficiency, secondary to degeneration.Upon visualization, the valve showed significant structural valve deterioration in the right and non-coronary cusps with tears at the commissural post between the right, left, and non.This was replaced with a 27mm pericardial bioprosthesis and inspection revealed good seating and no paravalvular leak.The patient was later discharged on pod #5.
