a Chest X-ray: cardiomegaly (arrow). b Twelve-lead electrocardiogram (ECG): sinus rhythm, normal QRS duration, and nonspecific repolarization abnormalities including T-wave flattening and inversion in the inferior and lateral leads II, III, aVF, V3–V6. c 2D Echocardiography: apical four-chamber (A4c) view showing dilated LV, trabeculation of apex, the apical segment of the interventricular septum, medium and apical segments of the lateral wall with two-layer aspect (arrow). d 2D Echocardiography: modified apical three-chamber (A3c) view with zoom showing trabeculation of the apex, medial, and apical segments of the inferolateral wall with thrombus between the recesses (arrow). e 2D Echocardiography: parasternal short-axis view at the intermediate level, between the papillary muscles and the apex revealing ratio between NC/C layers = 2.1 (arrow). f 2D Echocardiography: parasternal short-axis at the papillary muscles level showing dilated LV with posterior displacement of the papillary muscles (arrow)
