On (b)(6) 2013, a 23mm trifecta valve was implanted due to aortic stenosis.The valve was explanted on (b)(6) 2020, due to calcification.Upon explant pannus was noted on the subvalvular tissue of non-coronary cusp (ncc).An inspiris resilia aortic valve by edwards was implanted.The patient was reported to be stable condition.Additional information was requested but cannot be obtained.

The reported calcification and pannus was confirmed.Leaflet 3 (rcc) contained calcifications, with a tear, associated with a calcification, noted near stent post 1.Circumferential pannus ingrowth was noted on both the inflow and outflow surfaces.This ingrowth encroached onto the inflow surface of all three leaflets, narrowing the inflow diameter.While the leaflet tissue was flexible, the mobility of all three leaflets was limited where calcifications or pannus was present.The device history record was reviewed to ensure that each manufacturing and inspection operation was performed and the product met all specifications at the time of commercialization.The host-device interaction of calcification and pannus limited valve function, with the calcification caused change in tissue architecture culminating in a leaflet tear.
