It was reported that on (b)(6) 2022, a 23mm trifecta valve was successfully implanted.On an unknown date, exercise-related shortness of breath and stenosis of the native aortic valve was noted.The patient was admitted due to stenosis of the anterior ramus interventricularis and carotistenose.Echocardiogram showed the following eoa: 0,6 cm2 (420mtr/sec).On (b)(6) 2022 the device was explanted and a non-abbott device was implanted.Upon explant, the valve was heavily calcified; no tears were observed but the valve was noted as "stiff".The patient was reported to be in stable condition.

Explant due to stenosis of the valve was reported.The investigation found that all three leaflets contained calcifications, which limited the leaflet mobility.There was circumferential fibrous pannus ingrowth on the inflow surface of the valve.A tear was found in leaflet 2 which was associated with a calcification.There was a thin layer of fibrin on the outflow surface at the base of leaflet 1.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 calcifications and pannus noted on the valve could have contributed to the reported stenosis.There is no indication of a product quality issue with regards to manufacture, design, or labeling.
