Event Description
|
It was reported that on (b)(6) 2013, a 19mm sjm trifecta valve was implanted in the patient's aortic position with the everting mattress suture technique.An abbott sizer was used in the surgery.On (b)(6) 2021, the patient presented for a follow-up and moderate aortic regurgitation (ar) was diagnosed.After this, on an unknown date, the patient complained of difficulty breathing.On (b)(6) 20201, the trifecta valve was explanted, replaced with a 19mm sjm regent heart valve w/flex cuff.Prior to explant, the device was found to be torn on the left coronary cusp (lcc) and the right coronary cusp (rcc) stent post side.The physician has suspected that shortage of the valve intensity might have been attributed to this issue.The device got damaged at the cuff part upon explant.The patient is stable.No additional information was provided.

Manufacturer Narrative
|
Explant was reported due to regurgitation and a leaflet tear was found at explant.The investigation found that leaflets 1 and 3 were torn.There was focal fibrous pannus on the outflow surface of leaflet 1 and the inflow surface of leaflet 2.A calcifications was found at the tear site in leaflet 3.No acute inflammation was present.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications.The cause of the tears could not be conclusively determined; however, the tear noted in leaflet 3 was associated with calcifications and the fibrous pannus ingrowth noted on the outflow of leaflet 1 had the potential to induce increased stress on adjacent leaflets and create an unbalanced stress relief distribution between all leaflets during coaptation, leading to leaflet tears and reduced durability.
