The results of this investigation concluded there were degenerative changes in cusps 1 and 3, and cusp 1 contained one tear.There was organizing thrombus with focal acute inflammation on the sewing cuff of cusp 3.Gram and gms stains were negative for organisms.No significant calcifications were present in the valve.A review of the device history record showed the device met specifications prior to leaving abbott manufacturing facilities.There was no evidence found to suggest the cause of the tear 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.
