Pediatric acute heart failure caused by endocardial fibroelastosis mimicking dilated cardiomyopathy: A case report

Figure 1 Chest radiograph, color doppler echocardiography, and cardiac magnetic resonance of the child. A: Prominently enlarged heart with a high cardiothoracic ratio; B: Marked enlargement of the left ventricle (inner diameter 38.70 mm) with diffuse slight thickening of the endocardium; C: Thickening of the posterior wall of the left ventricle (purple arrow); D: A small amount of mitral regurgitation (yellow arrow); E: Bright-blood T₁-weighted image shows slight endocardial thickening of the left ventricle and slight thickening of the myocardium (orange arrow); F: Dark-blood T₂-weighted image shows diffuse ventricular wall hypokinesis without visible delayed enhancement abnormalities (orange arrow).
