A reported by the field clinical specialist, during device prep, the 23 mm sapien 3 ultra the valve appeared "to gap" in the valve rinse.A new valve was requested.The preliminary engineering evaluation inspection of the returned device revealed an acute fold/crease remained after the leaflet was flexed.

A supplemental mdr is being submitted for the completed engineering evaluation.Sections b.4, g.3, g.6, h.2 and h.3 have been updated.Corrections have been made to h.6 type of investigation, investigation findings and investigation conclusion.The event reported is anticipated in the risk management documentation for transcatheter heart valve procedures.A previous investigation into this type of event is captured in an edwards lifesciences technical summary and applies to this complaint.Additional assessment of the failure mode is not required at this time.The device was returned for evaluation.The returned device was visually examined for abnormalities, and it was noted that creases were observed on the leaflet.Additionally, an acute fold in the tissue remained after the leaflet was flexed.The ifu, current risk mitigations including design and manufacturing controls, and training manuals have been reviewed, and no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.The complaint for inadequate leaflet coaptation during device prep was confirmed based on the returned device engineering evaluation.A leaflet crease was confirmed during functional testing of the returned device.Visual inspections and tests support manufacturing mitigations are in place.However, available information suggests that a manufacturing issue (workmanship) may have contributed to the leaflet crease.Complaint histories for all reported events are reviewed against trending control limits monthly, and any excursions above the control limits are assessed and documented as part of this monthly review.An investigation was initiated.
