Additional Manufacturer Narrative
|
|
Explant due to an stenosis was reported.The investigation found that all three leaflets were torn.Leaflets 1 and 3 had fibrous thickening and calcifications.There was fibrous pannus ingrowth on the inflow surface of leaflets 1 and 3.No inflammation or significant calcification 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 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.
