As reported by a field clinical specialist (fcs), during the procedure of a 26 mm sapien 3 ultra resilia valve in the aortic position via transfemoral approach resistance noted when advancing the delivery system and the valve.A strut from the valve poked through the sheath as it was being advance and could not be advance any further.The valve, delivery system, and sheath were removed from the patient.A new sheath was advanced as well as a new valve and delivery system.The procedure was completed with a successful deployment and no complications to the patient.

A supplemental mdr is being submitted for correction and additional information.The following sections of this report have been updated: corrected d.9 date returned to manufacturer, h.3 device evaluated by manufacturer, h.6 component codes and investigation conclusions and investigation findings.Added new information to h.6 type of investigation.The device was returned to edwards lifesciences for evaluation and the following was observed.During valve pre-expansion, one (1) strut bent on the inflow side.During valve post-expansion, bent strut was corrected, frame is deformed/canted and leaflets wrinkled and dehydrated due to storage condition (prolonged crimping) during the return handling process.Imagery was provided from the site and revealed the following: tortuosity present in the patient's access vessels and calcification present in the patient's access vessels.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 the evaluation of the returned device.Calcification can reduce the vessel lumen diameter and may increase restriction leading to resistance.Calcification can also result in the creation of sub-optimal angles during delivery system insertion that may lead to resistance.Tortuous patient anatomy can create sub-optimal angles that can lead to non-coaxial alignment between the delivery system with crimped valve and sheath inner lumen.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.Available information suggests patient factors (tortuosity, calcification) and/or procedural factors (excessive manipulation/high push force) likely contributed to the event as tortuosity and calcification are present in the patient's access vessels.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.
