Event Description
|
The manufacturer was informed that on (b)(6) 2022, central leak and paravalvular leak was observed by tee after implanting the perceval valve size xl through full sternotomy.Reportedly, this perceval valve was implanted before coronary artery bypass and heart luxation.Ultimately, it was decided to remove the valve.Another xl valve was ultimately implanted in the patient with a good result.Based on the further information received, no malfunction with the valve was noted, there was no impact on the patient, approximately 20 minutes was added to the procedure as a result of the reported event, and patient was stable through the delay in the procedure.Based on the medical judgement received, it is possible that device dislodgment has been occurred due to the maneuvers and led to the reported regurgitation.

Manufacturer Narrative
|
Based on the medical judgment received, there was no malfunction with the valve, and it is possible that the cause of the reported event was attributed to the valve dislodgement due to the heart maneuvers after the implant of the device.Furthermore, from the document review performed, no manufacturing deficiencies were identified.Should the device or further information be received in the future, the manufacturer will provide a follow up report.

Manufacturer Narrative

The valve was returned to the manufacturer.After decontamination, the visual inspection performed on the returned prosthesis confirmed the absence of pre-existing defects.The hydrodynamic testing was conducted on the pvs 27/xl.The effective orifice area (eoa) at 70 bpm, 5.0 l/min of cardiac output and mean backpressure of 100 mmhg is 3.36 cm2, above the iso 5840 minimum requirement 1.70 cm2.For a cardiac output of 5.0 l/min and mean aortic pressure of about 100 mmhg, the regurgitant fraction is 5,4 % and it is below the requirement of iso 5840 (rf% < 15%) for a prosthesis of equivalent tad.No anomalies were observed during the open/close cycle in both normotensive and hypotensive conditions regarding the total and full coaptation of the leaflets.Based on the performed analysis, the reported event cannot be explained by any factor intrinsic in the involved device because no regurgitation and no open/close anomalies were observed during the functional test under hydrodynamic testing conditions.From the document review performed; no manufacturing deficiencies were identified.Based on the medical judgment received, there was no malfunction with the valve, and it is possible that the cause of the reported event was attributed to the valve dislodgement due to the heart maneuvers after the implant of the device.
