It was reported that on (b)(6) 2014, a 19mm trifecta valve was implanted in an aortic valve replacement.The native valve dimension was 22mm.In (b)(6) 2022, progression of aortic stenosis became apparent with a valve pressure gradient of 40mmhg.In (b)(6) 2023, the patient had a valve pressure gradient of 40mmhg and worsening dyspnea, and the patient was urgently hospitalized due to signs of heart failure.On (b)(6) 2023, the 19mm trifecta valve was explanted.Visualization of the explanted valve exhibited pannus, calcification, and thrombus.Thrombus could not be confirmed via echocardiogram previously.A replacement 21mm epic supra valve was implanted.The patient was reported to be stable.

Explant due to aortic stenosis, worsening dyspnea and signs of heart failure was reported.Also reported was visualization of the explanted valve exhibited pannus, calcification, and thrombus.The investigation found calcifications on all three leaflets with immobilization/limited mobility of all leaflets.There was fibrous pannus ingrowth on outflow surface of leaflets 1 and 2.Thin layer of fibrin present on inflow surface of leaflets 1 and 2.Leaflet 3 was torn.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 tear in leaflet could not be conclusively determined; however, was associated with calcifications.The calcifications found would have contributed to the reported stenosis.
