The device history record was reviewed to ensure that each manufacturing and inspection operation was performed.The review determined the process was performed and completed in accordance with sjm specifications and procedures.The results of this investigation concluded tears and/or perforations in all three cusps.There was surface pannus on the inflow surface of cusps 1 and 2, and the outflow surface of cusp 3.There was a thin layer of fibrin on cusps 2 and 3.Special stains were negative for organisms, and no acute inflammation or significant calcifications were present.There was no evidence found to suggest the cause of the fibrin, pannus, perforations, and 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.
