Figure 9
Histologic section of ISLP valve shows (a) a relatively normal part of the cusp “C,” covered with pannus “P.” (b) Body of the cusp shows a split between the cusp “C” and pannus “P” with organizing thrombus “T.” (c) The cusp shows mature pannus “P” with calcification of the cusp (asterisk). (d) Calcification of whole of the body of the cusp (asterisk). (a), (b), (c), and (d) Stain: Movat pentachrome. Original Magnification (a) ×10; (b), (c) & (d) ×5.
