Edwards received notification from a field clinical specialist that during a patient with a previously implanted 21mm edwards surgical valve, underwent a valve in valve procedure.As reported, a 20mm sapien 3 ultra resilia valve was prepped per ifu and implanted.The team decided to bvf with a 22mm true.The first attempt was unsuccessful.A second attempt was performed and valve fracture was achieved.The patient was not recovering well, so a tee was brought in and it was determined that the patient had moderate to severe aortic insufficiency (ai).The valve was positioned at the top of surgical frame to top of thv frame as intended.There was believed to be an issue with the movement of the leaflet due to overexpansion of the new thv.A second commander/20mm s3ur were prepped per ifu and the sapien valve was implanted.The patient recovered well and left the room stable.The initial reporter did not allege that any edwards devices were deficient.The perceived root cause was post-dilating the 20mm s3ur with 22mm true balloon to fracture the surgical valve.

Supplemental report submitted to include the completion of the engineering evaluation.The event reported is an anticipated in the risk management documentation for transcatheter heart valve procedures.A previous investigation into this type of event is captured in an edwards lifesciences technical summary and applies to this complaint.Additional assessment of the failure mode is not required at this time.Due to the unavailability of the complaint device, engineering was unable to perform any visual inspection, functional testing, or dimensional analysis.Per the technical summary, the ifu, current risk mitigations include design and manufacturing controls, and training manuals have been reviewed, no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.Through extensive complaint investigations, central regurgitation events post-deployment with or without report related to leaflet mobility for the s3, s3u, and s3ur valves have not been associated with device malfunctions or manufacturing nonconformances.Rather, the root cause for these events have historically been due to patient and/or procedural factors (malposition, slow recovery of blood flow, leaflet impingement due to calcification or guidewire, over-inflation, post-dilation, and/or under-expansion).The complaint valve central regurgitation was confirmed based on the information available to date.Available information suggests procedural factors (post-dilation to fracture pre-existing valve with non-ew balloon) likely contributed to the event as it was reported that ''the team decided to bvf with a 22mm true.The first attempt was unsuccessful.A second attempt was performed and valve fracture was achieved.A tee was brought in and it was determined that the patient had moderate to severe aortic insufficiency (ai).'' additionally, ''the perceived root cause was post-dilating the 20mm s3ur with 22mm true balloon to fracture the surgical valve.'' deploying the valve using more than the prescribed volume or attempting a second inflation may result in inability for the valve leaflets to properly function.The increase in valve diameter due to overinflation or post dilation may prevent proper motion of the thv leaflets resulting in thv regurgitation.Additionally, per the training manual, central regurgitation is an associated risk of post-dilation.Complaint histories for all reported events are reviewed against trending control limits on a monthly basis, and any excursions above the control limits are assessed and documented as part of this monthly review.Since no edwards product defects or labeling deficiencies were identified, no corrective or preventative action is required.
