It was reported that on (b)(6) 2013, a 21 trifecta valve was successfully implanted.On (b)(6) 2023, the patient presented to the hospital with shortness of breath.It was confirmed that the patient had experienced bilateral pleural effusion.On (b)(6) 2023, the patient was hospitalized due to severe aortic regurgitation.On (b)(6) 2023, the trifecta valve was explanted, and an unknown size non-abbott valve was implanted as a replacement.Post explant, there was no calcification or other visible valve failures.No additional information was provided.

Explant due to severe aortic regurgitation was reported.The investigation found there was fibrous thickening on all leaflets.All three leaflets were torn.There was fibrous pannus ingrowth on the inflow surfaces of leaflets 1 and 3 and on the outflow surface of leaflet 3.There were degenerative changes on leaflets 2 and 3.Micro-calcification was present on leaflet 3.No 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 tear could not be conclusively determined; however, the fibrous pannus ingrowth noted 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.Additionally, the degenerative changes noted to the tissue could have contributed to the tear formation.
