Contrast-enhanced CMR images in 6 different HCM patients demonstrating the diverse pattern and extent of late gadolinium enhancement in this disease. (A) extensive transmural LGE in the anterior wall (small arrows) with smaller focal area in the inferior wall (small arrows); (B) mid-myocardial LGE in the lateral wall (small arrows) and diffuse LGE in the ventricular septum which extends into the RV wall (large arrows) in a 26 year-old man with "end-stage" phase of HCM with an ejection fraction of 40%; (C) LGE confined to the LV apex (arrows); (D) LGE localized to the insertion area of the RV wall into the anterior (large arrow) and posterior ventricular septum (small arrow); (E) transmural LGE involving the majority of the ventricular septum (large arrow) and lateral wall (small arrow). (F) Basal short-axis image with transmural LGE located predominantly in the ventricular septum (arrows). RA = right atrium; RV = right ventricle; LA = left atrium; LV = left ventricle
