case_images: (A) A transthoracic four-chamber echocardiography image shows an aneurysm protruding from the posterior wall of the LV; the size of the aneurysm is 6.85 cm x 4.82 cm. (B) A color Doppler image shows a shunt from the left ventricle to the aneurysm (yellow arrow). (C-E) A coronary computed tomography angiography of curved planar reconstruction images show that the RCA mid-distal is in occlusion (C, yellow arrow), the LAD stent is unobstructed (D), and there is mild stenosis in the LCX mid-segment (E) (F) An axial CTA image shows that the lateral wall of the LV is interrupted continuously. (G) A volume-rendering CTA image shows a globular cavity and a narrow neck of the aneurysm (yellow arrow). (H-J) CMR four-chambered, short-axis and horizontal axis cine images show the aneurysm, and the wall of the aneurysm is continuous with the visceral pericardium (yellow arrow). (K-M) Late gadolinium enhancement images show a transmural delay enhancement of the lateral wall of the LV. The enhanced part of the ventricular aneurysm wall is composed of pericardial components. There is a small-sized thrombus around the ventricular pseudoaneurysm (M, yellow arrow).

case_images: Color Doppler showed a shunt blood flow signal from the area of the rupture to the ventricular aneurysm (Figures 1A,B), and the LV ejection fraction (EF) was moderately decreased (41%). A computed tomography angiography (CTA) showed that the RCA mid-distal was in occlusion (Figure 1C), the LAD stent was unobstructed (Figure 1D), and there was mild stenosis in the LCX mid-segment (Figure 1E). A horizontal axis image showed the ventricular aneurysm of the LV lateral wall (Figure 1F). A volume-rendering image showed that the narrow neck of the LV lateral wall was connected with the ventricular aneurysm (Figure 1G). LV lateral wall, a cystic cavity was seen communicating with the LV (Figures 1H-J, Supplementary Videos S1-S3), and the lateral wall of the cyst was continuous with the pericardium (Figure 1H, yellow arrow). Late gadolinium enhancement (LGE) images showed a transmural myocardial infarction of the LV lateral wall (Figures 1K,L). The wall of the aneurysm was composed of a delayed enhancement of the pericardium rather than the myocardium (Figures 1K,L). A small-sized thrombus could be seen in the aneurysmal wall (Figure 1M, yellow arrow).
