Delayed enhancement MRI images in our patients. a, b: 4-chamber view and corresponding short-axis view respectively, in a patient in group 2 (HCM patients without septal reduction therapy). No scar is detected; c, d: similar views in a patient in group 3 (HCM patients having undergone septal reduction therapy), demonstrating a thin subendocardial layer of fibrosis (arrow) resulting from surgical myectomy; e, f: same views in another patient in group 3, showing transmural delayed enhancement (arrow) in the basal septum, corresponding to transmural scarring resulting from interventional septal ablation
