Manufacturer Narrative

The manufacturer is following up with the site to retrieve further information regarding this event and the device involved.A follow up report will be provided upon receipt of any further information.

Event Description

The manufacturer was notified of an intraoperative explant of a perceval s sutureless aortic bioprosthesis pvs21 that occurred on (b)(6) 2023.Reportedly, at an ultrasound check after implantation, the valve was functioning properly, but after a few minutes, severe ai appeared in the form of a central leak.The valve was explanted and replaced.

Event Description

The manufacturer was notified of an intraoperative explant of a 21 mm perceval s sutureless aortic bioprosthesis occurred on 21 june 2023 during an isolated avr surgery performed through mics.Reportedly, at an ultrasound check after implantation, the valve was functioning properly, but after few minutes, severe ai appeared in the form of a central leak.The valve was explanted and replaced with a bioprosthesis from a different manufacturer (carpentier edwards 21 mm).Patient's annulus was determined to be 20-21 mm in size with no abnormal geometries and patient's native valve was bicuspid sievers 1.As reported, the perceval implant procedure was performed smoothly, with no collapsing issues, no positioning difficulties experienced and no malpositioning identified.According to medical judgement, the size of the perceval prosthesis was evaluated to be correct.It was reported that total cross clamp time was 49 minutes only and patient remained stable throughout the procedure with no impact in consequence of the event.

Manufacturer Narrative

Updated fileds: a2, a3, a4, b4, b5, g3, g6, h2, h3, h6, h10.The manufacturing and material records for the perceval heart valve and stent, model #icv1208-eu, s/n # (b)(6), as they pertain to the reported event, were retrieved and reviewed by the manufactureâ¿¿s quality engineering.The results confirmed that this valve has been manufactured and controlled in accordance with the specifications for a (model # icv1208-eu) perceval heart valve at the time of manufacture and release.The valve was returned to the manufacturer for analysis and was received in acceptable storage conditions.However, the pericardium appeared abnormally very stiff and showed difficulty in moving as if a dehydration process had started which could have been caused by the valve remaining for a period of time without storage liquid or being kept in an incorrect storage liquid that had altered the pliable properties of the leaflets.After decontamination, the valve was visually inspected without highlighting elements of non-conformity according to the specifications.A hydrodynamic testing was performed.The effective orifice area (eoa) at 70 bpm, 5.0 l/min of cardiac output and mean aortic pressure of about 100 mmhg was 1.38 cm2, above the iso 5840 minimum requirement of 1.05 cm2.For a cardiac output of 5.0 l/min and mean aortic pressure of about 100 mmhg, the regurgitant fraction was 9.3% which is below the requirement of iso 5840 (rf% < 10%) for a prosthesis of equivalent tad.It should be noted that, despite all the measured values were below the limits established by the iso, anomalies were observed during the valve diastolic phase: a slight central leakage was detected in normotensive conditions that increased to a moderate magnitude in hypotensive conditions.During the systolic phase, the valve showed no anomalies under normotensive conditions while valve opening was only partially reached under hypotensive conditions.From a comparison of the valve images in opening configuration acquired during the hydrodynamic testing versus the steady flow test performed at the time of release from manufacturing, it was observed that the returned valve showed a reduced opening of the leaflets (although respecting the iso limits) compared to what observed at the steady flow test.This may be a reasonable evidence that the mechanical characteristics (elasticity and flexibility) of the pericardium have been impaired to some extent.It follows that the tests, carried out in our laboratories, can only be partially considered representative of the behavior of the prosthesis during the implant.Based on the performed analysis, the reported event cannot be explained by any factor intrinsic to the involved device.The review of the manufacturing and material records, including visual inspection and steady flow test, confirmed that the device satisfied all the specifications at the time of manufacturing and release.It should be noted that, despite the results of the functional test performed on the returned device can only be partially considered representative of the behavior of the prosthesis during the implant, due to the compromised conditions of the pericardium, the values measured satisfied iso 5840:2021 requirements.
