As reported by field clinical specialist, during a transfemoral aortic valve replacement procedure with a 29mm sapien ultra resilia valve, the esheath+ was damaged when the valve was inserted, and a new sheath was needed.There was a lot of push force noted when the valve was inserted.Once the valve came out of sheath, it was noted that there was a bent strut.The physician attempted to pull the valve back in the sheath but was unable to.They decided to deploy valve in the aortic position.The strut opened up and there was no harm to the patient.

This is one of two manufacturer reports being submitted for this case.Please reference related manufacturer report no: 2015691-2024-00034.The valve remains implanted and was, therefore, not returned for evaluation.Imagery was provided and reviewed.Calcification and tortuosity were observed to be present in the patient's right access vessel.One (1) bent strut was observed on the inflow side of the valve.The bent strut was corrected after valve deployment.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.A review of edwards lifesciences risk management documentation was performed for this case.The reported event is an anticipated risk of the transcatheter heart valve procedure, additional assessment of the failure mode is not required at this time.An edwards technical summary applies to this event and establishes, through extensive complaint investigations, that events reporting resistance during delivery system insertion/advancement through the sheath and potential valve frame damage using the s3u/s3ur valve configuration have not been associated with device malfunctions or manufacturing nonconformances.Rather, the root cause for these events have been due to vessel tortuosity, calcification, undersized vessels, and/or steep insertion angle.In addition, valve frame and/or sheath damage can be a result of increased push force and any excessive device manipulation or sheath-valve interaction.Therefore, it is likely that these patient/procedural factors may have caused or contributed to the difficulty advancing the delivery system through the sheath and valve frame and/or sheath damage.Review of the ifu and training materials is detailed in the technical summary and continues to provide adequate instructions on device use, risks, and precautions.In addition, review of manufacturing mitigations is captured in the technical summary, which are still in place.With no unique issues or concerns raised with this complaint, this event will be included in ongoing monitoring and trending with no pra or capa required at this time.The valve frame damage was confirmed based on the provided imagery.Available information suggests patient factors (calcification, tortuosity) and/or procedural factors (excessive manipulation/high push force) likely contributed to the event as calcification and tortuosity was observed and one (1) bent strut was observed on the inflow side.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.
