Congenital heart disease
Microscopic
A. The sections show normal cardiac myocytes and mild endocardial fibrosis, covered by benign endothelial cells. There is no inflammation and no haphazard arrangement of muscle fibres.
B. The sections show cardiac myocytes and mild endocardial fibrosis, covered by benign endothelial cells. There is focal myofiber replacement by fibrous tissue with reactive hypertrophy (including increase of fiber size and nuclear size) of the remaining fibres. There is no inflammation and no haphazard arrangement of muscle fibres.
C. The section shows a laminated thrombus with focal calcifications and entrapped blood constituents. Special stains (GMS, Gram, PAS-D) did demonstrate micro-organisms.
Final diagnosis
A. Heart, right ventricle, muscle excision - mild endocardial fibrosis. B. Heart, ventricular septum, muscle excision - mild endocardial fibrosis and focal hypertrophic changes. C. Infundibulum clot, excision - laminated thrombus with focal calcification.
