Outflow and inflow of the explanted graft, as well as histological analysis of the valve. Panel A shows the outflow of the valve, with totally normal looking, coapting cusps; Panel B shows the outflow, and the inflammatory reaction to the abscess which was responsible for valvular distortion is seen in the upper right hand corner; Panel C shows the H+E histological slide, showing normal looking pericardium of the conduit and the inflammatory cells of the abscess cavity; Panel D shows the Factor VIII immunoassay of one of the cusps, positive for monolayered endothelial cells.
