As reported by the field clinical specialist, during a transfemoral tavr procedure with a 23mm sapien 3 ultra valve in the aortic position, during deployment the physician had great difficulty emptying the syringe.The inflation was slow and required excess force.The valve deployed without issue or problems.Per additional information provided, it took the physician approximately twice as long to empty the syringe, almost like there was something obstructing the flow of contrast.The approximate time of inflation/deflation was 20 seconds.After valve implant the commander delivery system was removed without issues.Upon removal, the fcs tested the delivery system on the back table and there was no difficulty inflating the balloon.The perceived root cause for the inflation/deflation difficulty was the collapsed balloon lumen while inside the body.

A supplemental mdr is being submitted due to engineering evaluation findings.Sections g6, h2, h6: component code, type of investigation, investigation findings, investigation conclusions and h10 has been updated.The device was not returned, and no imagery was provided for evaluation.As no device was returned, engineering was unable to perform visual inspection, functional testing, or dimensional testing.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 this adverse event is not required at this time.The complaint was unable to be confirmed due to the unavailability of the complaint device and /or applicable imagery.Therefore, a manufacturing non-conformance was unable to be determined.A review of lot history and device history record revealed no indication that a manufacturing non-conformance contributed to the event.As reported, "the valve was deployed with great difficulty in the body, it took the physician approximately twice as long to empty the syringe, almost like there was something obstructing the flow of contrast.The pacing run lasted twice as long as normal and while the valve deployed in the correct position and height, the physician was very concerned about how hard it was to empty the syringe during the deployment.Following the procedure, after valve implant and commander was removed, i tested the system on the back table.There was no difficulty inflating the balloon, the perceived root cause for the inflation/deflation difficulty was the collapsed balloon lumen while inside the body." it is possible that due to patient anatomy or procedural factors the guidewire lumen was kinked before valve deployment, leading to the reported constriction and subsequent inflation difficulties.However, without patient/procedural imagery or the returned complaint device, a definite root cause is unable to be determined.The ifu and training manuals have been reviewed and no inadequacies have been identified with regards to warnings, contraindications, and the directions/conditions for the successful use of the device.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.Therefore, no corrective or preventative action nor product risk assessment escalation is required at this time.
