case_images: Echocardiography of aortic valve. (A) Echocardiography of aortic valve (before operation). Yellow circle: aortic coronal valve with a slightly elevated echogenic mass, with a cross-sectional size of approximately 7mmx15mm. (B) Echocardiography of aortic valve (after operation). Normal position and function of the biological valve are, no obvious perivalve leakage.

case_images: The next day, echocardiography revealed severe regurgitation of aortic valve with vegetation formation (Figure 1).
case_images: Vegetation of aortic valve (HE staining). (A) Vegetation of aortic valve, HE staining (x200). Vitreous degeneration, cellulose like necrosis, calcification, and extensive infiltration of inflammatory cells. (B) Vegetation of aortic valve, HE staining (x400). Inflammatory cells with a large number of lobulated nuclei (neutrophils) and a small number of plasma cells.

case_images: The pathological examination of the aortic valve tissue after surgery showed that the valve tissue had fibrinous necrosis, calcification, with hyaline degeneration, and local infiltration of a large number of inflammatory cells, which was in line with the pathology of infective endocarditis (Figure 2).
