On 01 april 2014, an aortic valve replacement (avr) was performed and this 21 mm sjm trifecta valve was implanted.Concomitantly, a mitral valve repair was performed and a 24 mm sjm rigid saddle ring was implanted in the mitral annulus.On (b)(6) 2016, the patient was referred by her primary care physician for urgent care.On (b)(6) 2016, the valve was explanted due to early structural valve deterioration (svd), as a leaflet tear was observed.A 21 mm tissue valve from another manufacturer was implanted.Per report, there were no issues noted with the ring; therefore, it remains implanted.The patient is reported to be recovering.

The results of this investigation concluded there were tears in leaflets 1 and 3.There was circumferential fibrous pannus ingrowth on the inflow surface with narrowing of the inflow diameter.There was a thin layer of fibrin of leaflets 1 and 2.No acute inflammation or significant calcifications were present in the valve.A review of the device history record showed the device met specifications prior to leaving sjm manufacturing facilities.There was no evidence found to suggest the cause of the fibrin, pannus, or tears were due to an intrinsic defect in the valve, as supported by review of the valve's device history record and the analysis performed.The cause of the reported event remains unknown.
