Event Description
|
As reported by a field clinical specialist (fcs), during the procedure of a 29 mm sapien 3 ultra resilia valve in the aortic position via transfemoral approach.The initial valve got stuck within the 16fr esheath and could not be advanced through, because tine of stent was sticking out of the side of the sheath.Per the fcs, the event is likely more of patient anatomy related.The patients femoral anatomy was tight/diseased (per physician 5.5-6mm).The valve was also prepped by hospital staff with my oversight.The person crimping the valve has not crimped a valve in a long time and though it appeared the device was prepped correctly, this could be a possible cause.The second prepped 29mm valve serial was delivered and implanted without an issue, though it was very hard to push valve through the sheath.There is no clinical issue to the patient and patient is doing well in post op.2023-29390-01 - 2nd esheath.2023-29390-02 - 1st esheath.2023-29390-03 - 1st valve.

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 and investigation findings.Added new information to h.6 type of investigation.The device 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 provided from the site and revealed the following: one (1) valve strut appeared punctured through sheath.A review of the risk management documentation was performed, and no evidence of product non-conformances or labeling/ifu inadequacies were identified in the evaluation.The complaint was confirmed based on evaluation of provided device imagery.Available information suggests that patient factors (undersized vessel) and procedural factors (excessive manipulation) likely contributed to the event as the following was reported: ''the event is likely more of patient anatomy related.The patient's femoral anatomy was tight/diseased (per physician 5.5-6mm)''.Per the training manual, the minimum vessel diameter required for 29mm thv and 16f esheath+ is 6.0mm.Undersized vessels (e.G.Due to anatomical variation, pre-existing stent or graft, scar tissue, or fibrosis) can create a restricted pathway or constrained condition resulting in difficulty during sheath expansion and increased resistance during the advancement of the delivery system.Excessive device manipulation or high push force can lead to the valve struts interacting with the sheath shaft and result in the strut damage at the valve inflow side.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.
