It was reported that on (b)(6) 2014 a 21mm trifecta valve (tf-21a, 180110465) was successfully implanted during aortic valve replacement surgery.On 10 may 2023, the patient presented to the emergency room with complaints of increasing dyspnea and bilateral lower extremity swelling.The patient was diagnosed with cardiomyopathy, congestive heart failure, severe stenosis and aortic valve disorder.The leaflets were observed to be opening minimally.The patient was admitted for treatment and was stabilized.On (b)(6) 2023, the patient underwent an aortic valve replacement surgery to replace the trifecta valve due to deterioration.A 23mm non-abbott device was implanted.The explanted trifecta valve was observed to have small adherent of tan/grey calcified tissue.The patient is reported to be alive and well.

It was reported that the patient presented to the emergency room with increasing dyspnea and bilateral lower extremity swelling after nine years of implant.Also reported that the patient was diagnosed with cardiomyopathy, congestive heart failure, severe stenosis and aortic valve disorder.The leaflets were observed to be opening minimally.On (b)(6) 2023, the patient underwent an aortic valve replacement surgery to replace the trifecta valve due to deterioration.The explanted trifecta valve was reported to have small adherent of tan/grey calcified tissue.A more comprehensive assessment, including histopathological examination of the valve tissue could not be performed as the device was not returned for analysis.However, based on the information received, the reported event is consistent with structural valve deterioration (svd).A variety of factors may contribute to svd, including patient and biological factors: biological factors which can result in tissue degeneration such as calcification (from patient conditions predisposing to elevated calcium like renal disease etc.) or thinning of the prosthetic leaflet tissue (predisposing to leaflet tears) also could not be confirmed as the valve was not returned for histopathological examination.Stenosis was reported which could have been caused by pannus on the valve leaflets or calcification; both of which also can contribute to leaflet tears formation.Neither could be confirmed as the valve was not received for examination.The device history record was also reviewed to ensure that each manufacturing and inspection operation was performed, and the product met all specifications.Based on the information received, the cause of the reported incident could not be conclusively determined.There is no indication of a product quality issue with respect to labeling design or manufacturing of the device.
