CTICasesEndocardial Fibroelastosis
Imaging findings
Cardiac MRI shows severe, concentric left ventricular wall hypertrophy with excessive trabeculations and a distinct circumferential band of subendocardial late gadolinium enhancement (LGE) involving the left ventricle.
Key takeaways
Endocardial fibroelastosis (EFE) is characterized by diffuse thickening of the endocardium by collagen and elastic fibers. EFE is strongly associated with congenital heart diseases (such as aortic coarctation or hypoplastic left heart syndrome) and manifests on cardiac MRI as a circumferential subendocardial LGE pattern.
