As reported by the edwards field clinical specialist, post valve deployment of a sapien 3 ultra resilia valve in the aortic position, mild to moderate central leak was noted.A 2nd sapien 3 ultra resilia valve was implanted and the central resolved.There was no harm to the patient.The perceived root cause was due to annular calcium, a couple of large deposits of calcium.

Update to h2 (type of investigation, investigation findings and investigation conclusions) h6 and h10 to reflect engineering evaluation.The event reported is 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.The complaint for deployed valve exhibits central regurgitation is unable to be confirmed due to no imagery, medical report, nor device provided.A review of the dhr did not provide any indication that a manufacturing non-conformance would have contributed to the complaint event.A review of the ifu/training materials revealed no deficiencies.During the manufacturing process, all sapien 3 ultra resilia valves are 100% visually inspected for defects and 100% tested for proper coaptation under physiological backpressure conditions prior to release for distribution.Therefore, it is highly unlikely that a manufacturing defect or device malfunction contributed to the complaint event.In this case, significant calcium deposits were reported within the patient's annulus.Although transcatheter heart valve depends on native landing zone calcification for anchoring, bulky calcification within the landing zone may impact the ability for the thv leaflets to properly function.The bulky calcium can impinge on the thv leaflets, preventing them from proper coaptation and lead to regurgitation.In this case, the valve exhibits central regurgitation after valve deployment was unable to be confirmed.The available information suggests that patient factors (calcification) likely contributed to the complaint event.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.
