Event Description
|
On (b)(6) 2022, after implanting perceval plus valve pvf-xl through full sternotomy, central leak was detected in the echo imaging and it was discovered that the leaflets were not coaptating.Consequently, it was decided to explant and re-implant the valve.However, despite repeating the procedure, central leak in echo imaging persisted, leading to removal of the valve.Ultimately, edwards inspiris resilia valve 25 mm was utilized to complete the procedure.No adverse patient effects were reported.Reportedly, upon examining the explanted pvf valve, it was discovered that one of the leaflets was shorter than the others.Based on the further information received, no pvf valve malfunction or mis-sizing were identified prior to the event.The procedure was a combined coronary artery bypass grafting and aortic valve replacement (cabg-avr), and the patient geometries were not considered abnormal.The procedure was delayed by one hour, but patient remained in stable condition throughout the procedure.There was no additional debridement or annular restructuring performed prior to the second valve implant.

Manufacturer Narrative

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 effective orifice area (eoa) at 70 bpm, 5.0 l/min of cardiac output and mean backpressure of 100 mmhg is 3.84 cm2, above the iso 5840:2021 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 5840:2021 (rf% < 15%) for a prosthesis of equivalent tad.No anomalies were observed during the open/close cycle in both normotensive conditions regarding the total and full coaptation of the leaflets.In hypotensive conditions, on the other hand, a not complete opening of the leaflets was found.This is in contrast with what is documented by the images retrieved on the dhr relating to the tests carried out for the release of the product.The reason for this difference is reasonably attributable to the imperfect condition of the prosthesis at the time of receipt in the laboratory.In any case, the observed feature is totally unrelated to the reported coaptation issue which, on the contrary, appears complete and totally comparable with the dhr image.Based on the performed analysis, the reported event cannot be explained by any factor intrinsic in the involved device because the claimed issues were not observed during the investigation carried out (i.E., hydrodynamic test).Furthermore, from the document review performed.No manufacturing deficiencies were noted.As such, the cause of the event cannot be traced to the device.Should further information be received in the future, a follow up report will be provided.
