Event Type  Injury  

Manufacturer Narrative

The gelweave valsalva graft is made of woven polyester, which has been impregnated with gelatin.The gelatin serves in place of fibrin, which seals the polyester prosthesis during normal pre-clotting.If excess gelatin mass were to accumulate inside the graft, this could lead to embolization, resulting in a partial or total blockage of blood flow in an affected vessel.The severity of harm would depend upon the location of the emboli.Cerebral arteries were involved, stroke may occur or peripheral embolism to a 3-5mm blood vessel.The investigation is still in progress; therefore, a conclusion has yet to be established.A supplemental report will be submitted accordingly upon investigation completion.

Event Description

It was reported that a 29mm valved conduit had gel-like debris inside the graft after implant.Per rep the graft immersed in saline for 5 minutes.The graft did not dry out after immersing in saline prior to implant.The debris was seen by surgeon and removed using a sucker.The product was in the rep's inventory and kept in proper conditions.The surgical team could clearly scrape the debris off and were using the sucker tip to remove anything they could see.It was noticed on both parts of the graft.Per medical records the patient presented with ascending aortic aneurysm, aortic insufficiency, and underwent bentall procedure.The echo reviewed valve working normally.The patient was discharged home in good condition on pod #4.

Manufacturer Narrative

Based on the information available, the complaint of gel-like debris is confirmed by product evaluation, however, a manufacturing non-conformance could not be confirmed as the returned fragment would have passed visual inspections during manufacturing.The device history record (dhr) was reviewed and showed that this device met all manufacturing and sterilization specifications for product release prior to distribution.No issues were identified that would have impacted this event.Edwards will continue to review and monitor all events.Trends are monitored on a monthly basis and if action is required, appropriate investigation will be performed.

Manufacturer Narrative

Customer report of gel-like debris was confirmed.Returned valsalva graft fragment had traces of blood residue and was approximately 5cm long in its as received un-stretched state.A clear, gel-like particulate approximately 3mm long was observed on the outer folds of the graft.No other visible inconsistencies were observed from returned graft.
