As reported by a field clinical specialist (fcs), during the procedure of a 23 mm sapien 3 ultra valve in the aortic position via transfemoral approach, the valve had resistance getting through the 14 fr esheath+ and the valve skirt struts bent backwards before the valve made it to the split portion of the esheath.A new system was prepared and the valve was used and implanted correctly in the aortic position.Upon removal, the commander delivery system was not damage however, a sheath puncture was noted on the esheath+.

A supplemental mdr is being submitted for correction and additional information.The following sections of this report have been updated: corrected h.6 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: patient's right access vessel had presence of calcification and tortuosity.One (1) strut bent outward and strut was exposed 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 through provided imagery.An existing technical summary written by edwards lifesciences captures the root cause analysis for complaints evaluated for resistance with delivery system and valve frame damage as a result from increased push force.The root causes identified in technical summary were tortuous patient anatomy, calcification, steep insertion angle and excessive device manipulation/ high push force.As reported, ''the valve had resistance getting through the 14 fr esheath+ and the valve skirt struts bent backwards before the valve made it to the split portion of the esheath.'' also, per the imagery evaluation, the valve was damaged on the inflow side and protruded through a tear in the esheath.The presence of the above factors can create challenging pathway during delivery system advancement, leading to resistance.More than one of these factors can compound to further exacerbate the patient/procedural conditions and increase the likelihood of encountering resistance during delivery system advancement through the sheath resulted in frame damage.The technical summary also outlines the extensive manufacturing mitigations in place to detect a defect or nonconformance associated with this issue.There are several 100% in-process inspections (visual) performed in manufacturing process and product verification testing (functional and visual) on a sampling plan basis performed prior to lot release.These inspections and testing support that it is unlikely that a manufacturing non-conformance contributed to the complaint.As such, available information suggests that patient factors (calcification, tortuosity) and/or procedural factors (excessive device manipulation, high push force, steep insertion angles) may have contributed to the reported event.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.A product risk assessment (pra) and a corrective action preventative action (capa) were previously initiated to capture the investigation of these type of events and drive any potential corrective/preventative actions.
