Double-chambered left ventricle with a thrombus in an asymptomatic patient: A case report

Figure 1 Echocardiography. A: In the three-chamber view of echocardiography, the left ventricle (LV) is divided by an abnormal muscle bundle (orange arrows), along with tears in the LV apical lateral walls; B: The parasternal short-axis view of echocardiography shows the LV is separated by an abnormal muscle bundle (orange arrows) in the LV apical lateral and inferior walls.

Figure 2 Coronary computed tomography angiography. A: In the four-chamber view, two left ventricular (LV) chambers are divided at the lateral wall of the LV (blue arrows), and the accessory chamber is surrounded by normal myocardium (orange arrows); B: In the short-axis view, the LV chambers are surrounded by normal myocardium (orange arrows) and are separated at the posterolateral wall of the LV (blue arrows).

Figure 3 Follow-up echocardiography. A: In the apical two-chamber view of the echocardiogram, spontaneous echo contrast with a probable thrombus (orange arrows) is shown in the accessory chamber. B: During contrast echocardiography, contrast does not penetrate along the apical inferior wall. The area (orange arrow) is probably a thrombus.
