Fungal endocarditis. The vegetations in this image cover the entire ventricular aspect of a bovine bioprosthetic valve as seen from the aortic (A) and ventricular (B) aspects of the bioprosthesis, and result in valvular stenosis. The tissue valve shows splaying of the collagen bundles by invading organisms (C). Note the absence of inflammatory cell reaction. The PAS stain demonstrates yeast forms consistent with Candida (D).


Endocarditis of a porcine bioprostetic valve is illustrated here.
