a Material remnants of the calcified mass removed from the right ventricle with surgical intervention. The remnants were conglomerated and had high consistency. b On the right side, the material of the pulmonary artery with a fibrinoid aspect and calcium nodes is seen. c Histopathological examination revealed a homogeneous, eosinophilic, largely acellular lesion with extensive areas of dystrophic calcification (hematoxylin and eosin stain, original magnification ×10). d The amorphous, fibrin-like material and hyaline formation in some areas is mixed with extravasated erythrocytes, spumous cells, and mild inflammatory cells
