As reported by an edwards lifesciences affiliate in france, during an urgent tavr procedure with a 26mm sapien 3 ultra transcatheter heart valve, the team was unable to prepare the commander delivery system due to unknown reasons.Another commander delivery system was prepared but the valve could not be implanted because the patient passed away on the table.Per the initial reporter "the patient passed away on the table due to the time lost waiting to prepare the device".Per initial engineering evaluation of the returned device, no abnormalities or defects were noted.Multiple attempts have been made to obtain additional information however the hospital will not be providing further information.The cause of death and status of the patient prior to the procedure remains unknown.This event is being conservatively reported.

The delivery system was returned for evaluation.During manufacturing of the commander delivery system, the delivery system and components are inspected several times throughout the manufacturing process.In addition, product verification testing was performed on a sampling basis and all testing met specifications.These inspections performed during manufacturing process and testing performed during product verification support that it is unlikely that a manufacturing non-conformance contributed to the reported events.During visual inspection, no visual abnormalities were noticed on the delivery system, including the balloon.An inflation test was performed on the returned device.The balloon was inflated as expected with and without the received stopcock attached at inflation port.No leakage was observed.The ifu and device preparation manual were reviewed and no ifu or training deficiencies were identified.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.A review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of the failure mode is not required at this time.Since no device problem was identified affecting distributed product, no pra is required.Additionally, since no edwards defect, which could have resulted in the complaint, was confirmed, no preventative or corrective actions are required.The delivery system prepping difficulty was unable to be confirmed.Functional testing of the returned delivery system suggests no device defect.A review of ifu/training materials revealed no deficiencies.Per the event description, ''during device prep, a leakage in the commander delivery system balloon was noted before the valve was placed.'' however, during product evaluation, no abnormalities were noticed on the balloon or delivery system during evaluation., balloon inflated as intended and no leakage was observed.As no device defect was noted during the evaluation, a definitive root cause is unable to be determined at this time.
