It was reported that on (b)(6) 2013, a 21mm sjm trifecta valve was implanted in the patient's aortic position.Around 2018, the patient began showing signs of aortic stenosis(as), and ended up going into heart failure.On (b)(6) 2021, the patient presented with moderate stenosis, cardiac insufficiency, and a high gradient.The sjm trifecta valve was explanted and replaced with a 21mm non-abbott device to resolve the event.Upon explant, calcification was confirmed mainly in the non-coronary cusp (ncc), but other leaflets were confirmed to have generally sclerosed as well.Struts of the ncc part were confirmed to have adhered to the valsalva wall.There was a pannus-like ingrowth at the adhered part, but the ingrowth had not caused the leaflet dysfunction.The patient remained hemodynamically stable throughout the procedure.The patient is in stable condition postoperatively.No additional information was reported.

Explant was reported due to stenosis, cardiac insufficiency and high gradient.The calcifications and pannus noted at explant were confirmed, with all three leaflets containing calcifications and fibrous pannus ingrowth on the inflow surface.All three leaflets had fibrous thickening and contained tears.Two of the tears were associated with calcifications, while the other tear had marked degenerative changes including a denatured appearance to the collagen present at the tear site.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 calcifications and pannus noted could have contributed to the reported stenosis and the tears found in the valve.
