As reported by an edwards australia affiliate, during a transfemoral tavr procedure with a 26mm sapien 3 ultra valve, as the operator aligned the valve in the commander delivery system balloon, the valve overshot the distal marker, and was pushed up to the nosecone.This was due to additional turns on the wheel that the operator accidentally made during final adjustment in the descending aorta.It was decided to cross the valve with a misaligned device.However, attempts to cross the valve annulus were unsuccessful, and it was noticed that the distal part of the valve frame was flared a bit.It was decided to deploy the valve in the descending aorta.The valve was deployed without any complications.A second valve was successfully implanted in the aortic annulus.The patient was transferred to the icu in stable condition for monitoring overnight and was discharged 72 hours later.

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 not returned for evaluation.Due to the unavailability of the complaint device, engineering was unable to perform any visual inspection, functional testing, or dimensional analysis.Per the technical summary, the ifu, current risk mitigations include design and manufacturing controls, and training manuals have been reviewed, no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.In this case, the reported event for valve frame damage was unable to be confirmed as no device or image was returned.As such, available information suggests that patient factors (calcification) and/or procedural factors (excessive device manipulation, improper valve alignment) may have contributed to the complaint event.There may be cases where the valve cannot be deployed at the intended location.This may require deploying the valve at a non-target location.Although well tolerated, the long-term effects are not completely understood.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.Since no edwards product defects or labeling deficiencies were identified, no corrective or preventative action is required.
