Heart, Valve - Inflammation, Suppurative in a female F344/N rat from a chronic study. Suppurative inflammation is present in the mitral valve (arrows).

Heart, Valve - Inflammation, Suppurative in a female F344/N rat from a chronic study (higher magnification of Figure 2). Suppurative inflammation of the mitral valve has aggregates of bacteria (arrows).

Heart, Valve - Inflammation, Chronic in a female F344/N rat from a chronic study. Mixed inflammatory cells are present within the thickened mitral valve (arrows).

Heart, Valve - Inflammation, Chronic in a female F344/N rat from a chronic study (higher magnification of Figure 4). Mixed inflammatory cells and proliferation of mesenchymal cells result in thickening of the mitral valve.
