On (b)(6) 2023, a perceval valve size m (this case) was implanted in the patient whose native valve was bicuspid type 1.After implantation and de-clamp, mild pvl in non-coronary part was noted.Reportedly, surgical site was closed but was re-opened because blood pressure went low.As such, the valve was explanted, and another perceval valve size l was implanted instead (b)(4).

Updated fields: b4, g3, g6, h2, h3, h6.The manufacturer attempted to retrieve further information regarding this event, but no further information was provided despite manufacturer's multiple attempts of follow up.The manufacturing and material records for the perceval heart valve and stent, model # icv1209-jp, s/n # (b)(6), as they pertain to the reported event, were retrieved and reviewed by a manufacture¿s quality engineering.The results confirmed that this valve has been manufactured and controlled in accordance with the specifications for a (model # icv1209-jp) perceval heart valve at the time of manufacture and release.The valve 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 23/m and a demo accessory kit.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 #23, no problems were encountered during the ballooning phase: the sealing at the annulus level is guaranteed as visible in attached pictures; 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 and despite the residual deformation observed at the inflow side level, the water level remained stable under the leaflets free edge.Based on the performed analyses, the reported event cannot be explained by any factor intrinsic in the involved device.Furthermore, from the document review, no manufacturing deficiencies were noted.The deployment simulation, performed on the returned valve, did not highlight anomalies and the valve resulted globally well deployed and fixed in stable way with no paravalvular leaks.As such, it is possible to exclude the relationship between the reported issue and the returned device quality.Should further information be received in the future, a follow up report will be provided.
