As reported by an edwards field clinical specialist, during the tavr procedure, there were complications, including major bleeding and difficulty using the device.Additionally, there was a major vascular complication at the access site.This vascular complication led to the patient's death and necessitated unplanned surgery.Per a voluntary medwatch, the commander delivery system could not be withdrawn through the esheath, and the sheath layers were separated.

As reported by the edwards territory manager, after deployment of a 29mm sapien 3 valve in the aortic position, difficulty was encountered during the withdrawal of the commander delivery system and the 16fr esheath+ at the lower aorta, just above the rcia.The delivery system was wedged into the expansion seam opening at the end of the esheath.Although there appeared to be coaxial alignment upon re-entry into the distal end of the esheath, there was angulation from the aorta into the rcia.There was no crossing difficulty and no retained volume in the balloon.Several minutes passed between deflation and withdrawal of the system.The vascular complication that led to the patient's death was damage to the right common femoral artery, and an unsuccessful attempt was made to repair the artery.It was noted that the "sheath layers were separated," with the inner liner at the distal tip appearing very involved with the delivery system.During the removal of the system, an attempt was made to separate the delivery system and esheath by slight rotation of the delivery system and esheath, and confirming deflation of the balloon.No other damage was noted to any other device after the withdrawal of the system.

A supplemental mdr is being submitted due to engineering evaluation findings.Sections h6: type of investigation, investigation findings, and investigation conclusions and h11 have been updated.The device was not returned as it's in possession of the hospital.The event reported is an 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.Imaging was provided and revealed that tortuosity was present in the access vessel on the right side.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.Through extensive complaint investigations, events reporting difficulty/inability withdrawing catheter through patient vasculature or through the sheath have not been associated with device malfunctions or manufacturing nonconformances.Rather, the root cause for these events have historically been due to patient factors, non-coaxial withdrawal, altered balloon profile, damaged sheath, and/or damaged guidewire.In this case, the withdrawal catheter through sheath with difficulty to withdraw system was unable to be confirmed.The available information suggests patient factors (tortuosity) and/or procedural factors (damage sheath) likely contributed to the reported event.Patient factors (i.E.Calcification, tortuosity, scar tissue, or small vessel size) may cause constrained sections of the anatomy that interferes with passage of the delivery system and causes difficulty during withdrawal.Additionally, if the sheath was previously damaged, it can cause further resistance as the delivery system is withdrawn into it.Per the technical summary, the instructions for use (ifu), training manuals and current risk mitigations have been reviewed.No inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.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.
