A supplemental mdr is being submitted for correction and additional information.The following sections of this report have been updated: corrected h.6 component codes and investigation conclusions.Added new information to h.6 type of investigation and investigation findings.The sapien 3 ultra valve was not returned to edwards lifesciences for evaluation.Without the device returned for evaluation, visual inspection, functional testing and dimensional analysis were unable to be completed.Imagery was not provided for review.A review of the risk management documentation was performed, and no device malfunction or difficulty contributed to the occlusion harm, including the commander delivery system, the ew inflation balloon, and the sapien 3 ultra valve.The complaint was unable to be confirmed due to unavailability of relevant procedural imagery.The reported event does not allege a malfunction that could be related to an edwards manufacturing deficiency.A review of ifu/training materials revealed no deficiencies.As reported, ''during the procedure of a 23 mm sapien 3 ultra valve in the native aortic valve via transfemoral approach.The patient is a risk for left main (lm) occlusion due to effaced sinuses.A non-ew stent was parked in the left coronary artery (lca) on a run through intervention wire.This stent and wire were through a guide catheter which was backed out of the lm.The 23 mm sapien 3 ultra valve was deployed in an 80/20 position and the patient's blood pressure did not recover.An attempt to re-engage the lm and retract the stent back to the lm from further distal in the lca.The wire was pinned behind the thv stent frame and was unable to easily retract the stent into position.After pulling more firmly the stent balloon broke and dislodged from the stent''.In this case, a non-ew stent was parked at left coronary artery through the intervention wire prior ew sapien 3 ultra valve was deployed.If the intervention wire was not properly retracted from the native annulus, which could lead the intervention wire ''pinned behind the thv stent frame'' or trap between the frame and native annulus.As such, available information suggests that procedural factors (improper retracted intervention wire with non-ew stent prior thv deployment) may have contributed to the complaint event.However, a definitive root cause was unable to be determined.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.No ifu/labeling/training manual inadequacies were identified.Therefore, no corrective or preventative action nor product risk assessment is required at this time.
