On (b)(6) 2024, a perceval valve pvs21 was implanted in a patient without any problem.After heart-lung machine was disconnected, pvl was noted by echo.As such, valve was explanted and epic 21mm was implanted instead.No further information is available at this time.

The manufacturing and material records for the perceval heart valve and stent, model #icv1208, s/n # (b)(6), as they pertain to the reported event, were retrieved and reviewed by the manufacture¿s quality engineering.The results confirmed that this valve has been manufactured and controlled in accordance with the specifications for a (model #icv1208) perceval heart valve at the time of manufacture and release.Device was returned to the manufacturer.After decontamination, the valve was visually inspected without observing any macroscopic anomalies and/or pre-existing defects according to the specifications.The replication of collapsing phases was performed using the returned valve pvs 21/s and a demo accessory kit, in order to attempt to reproduce the reported event.No problems were encountered in the collapsing phase, and the replication has been completed with a good result.During the simulation of the valve deployment in silicon aortic root #21, no problems were encountered during the ballooning phase: the sealing at the annulus level was guaranteed; thus, the valve remained fixed within the annulus.Then, inserting some water in the aortic root from the outflow side, no paravalvular leaks were observed during the simulations.Considering the static conditions of the test, the water level remained stable under the leaflets free edge.Based on the performed analyses, it is possible to exclude the relationship between the reported issue and the returned device quality.Furthermore, from the document review performed, no manufacturing deficiencies were noted.Based on the information received, the cause of the event was related to under-sizing (use-error).
