Echocardiogram (Panel A) and chest computed tomography (CT, Panel B) revealed a large mass (asterisks) encasing the anterolateral side of left ventricle (LV) with partial loss of epicardial fat echodensity (white arrows) and pericardial effusion. Cardiac CT (Panel C) and conventional angiography (CAG) (Panel D) demonstrated a heterogeneously enhanced mass measuring 6.0 × 4.7 × 4.0 cm and total occlusion of the middle left anterior descending artery (LAD, arrowheads) with heavy calcification.
