Cardiac uhrasonography: A hypoechoic mass of about 36 mm x 23 mm on the right ventricular wall, narrowing of the right ventricular inflow tract (Figure 1), a small amount of pericardial effusion, patent foramen ovale (2 mm), and patent ductus arteriosus (2 mm). Cardiac CT angiography (CTA): An elliptical low-density shadow of 35 mm x 23 mm on the right ventricular wall, with the right ventricle compressed (Figures 2A,B).
(A) Plain CT scan: Enormous space-occupying mass on a right ventricular wall, with compressed right ventricle cavity. (B) 3D reconstruction of cardiac blood flow: The right ventricular inflow tract was compressed by tumor, without obvious blood flow filling.

Part of the myocardial tissue was enlarged along the boundary between the tumor and the myocardial tissue, and the marginal myocardial tissue was cut from multiple locations for pathological examination to ensure complete tumor resection, the fibroma was completely removed (Figures 3A-C), and the right ventricular wall wound was directly sutured.
Examination under a light microscope (A); Magnification: 20x, and (B) 40x (hematoxylin and eosin staining).
