Intraoperative inspection and histopathology of the mitral valve. a. Intraoperative appearance of anterior mitral annuloplasty ring dehiscence. b. Low-power (X 50 original magnification) microphotograph of tissue destruction in the 3 layers of the anterior mitral valve observed after elastica van Gieson staining. F = lamina fibrosa; V = lamina ventricularis; S = lamina spongiosa. c. High-power (X400 original magnification) microphotograph of neutrophils infiltration on left ventricular and atrial aspects of mitral valve observed after haematoxylin and eosin staining. Similar observations (not shown) were made on the posterior mitral valve. d. Widely necrotic (N) anterior mitral valve. e. High-power (X400 original magnification) microphotograph in the area surrounded by black line in Fig. 3d showing the accumulation of gram-positive staphylococci (arrows). f. Low-power (X50 original magnification) microphotograph of extensive inflammation and necrosis around the suture threads in the anterior mitral valve observed after haematoxylin and eosin staining. g. High-power (X400 original magnification) microphotograph showing necrosis and the infiltration of neutrophils
