Pathological images of the resected tissue. Amorphous fibrous tissue surrounding the multiple nodular calcifications, lymphocyte infiltration and hemosiderin deposition were confirmed in the fibrous tissue (A, arrowheads). Neoangiogenesis occured in the mitral valve (B, arrowheads). CAT was stained by phosphotungstic acid-hematoxylin (PTAH) stain (C) and Von Kossa stain (D). Fibrin around CAT and calcification of CAT were shown in blue/purple by PTAH stain (C). Calcification of CAT was shown in black/brown by Von Kossa stain (D). In comparing (C) with (D), the area that was stained in (C) but not in (D) indicated fibrin attached to CAT (C, arrowhead)
