In (b)(6) 2011, an aortic valve replacement procedure was performed with this 23 mm sjm trifecta valve.Post procedure, the patient presented with acute chest pain and a reduction in hemodynamic performance.Echocardiography revealed leakage from one of the cusps.The valve was explanted (date unknown) and during the procedure, one of the cusps was noted to be torn.The valve was replaced with a 21 mm tissue valve from another manufacturer.The patient was reported to hemodynamically stable.Bacteriological examination result was negative.

The results of this investigation concluded tears in cusps 1 and 3 and fibrous pannus ingrowth on the outflow surface of cusp 1 and inflow surface of cusp 3.Fibrous pannus ingrowth and a thin layer of fibrin were found on the inflow and outflow surfaces of each cusp.There was no evidence of inflammation and gram stains were negative for organisms.No evidence was found to suggest the cause of the tears, fibrin and pannus was 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.
