During a transfemoral valve in valve procedure, a 29mm sapien 3 valve was implanted in a failing non-edwards surgical aortic valve.Difficulties were encountered during the inflation of the sapien 3 valve.The distal end of the commander delivery system balloon inflated, but the proximal end of the balloon did not inflate.The initial valve landed too ventricular.A second sapien 3 valve was prepared and deployed in the initial sapien 3 valve where intended.No injury to the patient was reported.The patient was transferred to recovery in stable condition.Both valves remain implanted in the patient.

During a mitral valve in valve procedure, a 29mm sapien 3 valve was implanted in a failing non-edwards surgical mitral valve.Difficulties were encountered during the inflation of the sapien 3 valve.The distal end of the commander delivery system balloon inflated, but the proximal end of the balloon did not inflate.The initial valve landed too ventricular.A second sapien 3 valve was prepared and deployed in the initial sapien 3 valve where intended.No injury to the patient was reported.The patient was transferred to recovery in stable condition.Both valves remain implanted in the patient.

The commander delivery system was returned to edwards for evaluation.The delivery system was fully inserted through loader assembly, the stylet was inserted and the system was locked at the default marker.No flex or fine adjust was used.The valve was not returned.No damage to inflation balloon was observed and 1ml of residual fluid was left in balloon.The balloon was unpleated and unfolded from use.Visual inspection revealed no abnormalities on the inflation balloon.Review of the provided 3mensio report revealed the patient's annulus with a previously implanted valve.During functional testing and dimensional analysis, the device was able to be inflated as designed.The fully inflated delivery system was held for 3 seconds and deflated in less than 20 seconds.Specifications were met.The instructions for use (ifu), device preparation manual, and procedural training manual were reviewed for instructions/guidance on device preparation/usage.Do not mishandle the delivery system or use it if the packaging or any components are not sterile, have been opened or are damaged (e.G.Kinked or stretched), or the expiration date has elapsed.Visually inspect all components for damage.Ensure the edwards commander delivery system is fully unflexed and the balloon catheter is fully advanced in the flex catheter.To prevent possible damage to the balloon shaft, ensure that the proximal end of the balloon shaft is not subjected to bending.Verify proximal balloon shoulder greater than 1 cm distal to the sheath marker.Unlock inflation device.Initiate rapid ventricular pacing ensuring 1:1 capture, sbp < 50 mmhg, and pulse pressure < 10 mmhg.Confirm placement of center marker within optimal initial center marker zone.Begin initial deployment with a controlled slow inflation.Fully inflate and hold for 3 seconds to ensure complete deployment.Completely deflate the balloon.Balloon should be fully deflated and un-flexed prior to retraction into sheath.Stop pacing and withdraw the balloon from the native valve in this case, the complaints were not confirmed based on the evaluation of the returned device.The investigation of the device revealed no indication that a manufacturing non-conformance contributed to the event.A review of the ifu and training manuals revealed no deficiencies.Per provided notes from site the root cause most likely the s3 secured itself on the pre-existing non-edwards valve and the commander delivery balloon slipped ventricular during inflation so that more of the distal part of the balloon was inflating before the proximal end of the balloon.As such it is possible the thv came into contact with the previously implanted valve, impeding the advancement of thv while the delivery system was advanced, causing the valve to move proximally on the delivery system.And during the inflation of the valve due to its position causing the inflation balloon to inflate distally first leading to the noted difficulties.Although a definite root cause was not able to be determined, the available information suggests that patient factors (previous valve), in addition to procedural factors (improperly aligned valve) may have contributed to the event.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.
