(b)(4).The results of this investigation concluded all three cusps were fibrotically thickened, and contained fibrous pannus ingrowth on their inflow and outflow surfaces.All three cusps were retracted, and cusps 2 and 3 contained focal calcifications.Cusp 3 contained two tears.There was no acute inflammation and gram stains were negative for organisms.No evidence was found to suggest the cause of the fibrous thickening, pannus, calcifications, cusp retractions and cusp tears 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.
