CMR definitions of the six patterns of left ventricular hypertrophy and remodeling in aortic stenosis. Schematic representation of the left ventricular structure alongside CMR short-axis images of the left ventricle in end-diastole. Normal ventricular structure: characterised by a normal LV mass index, indexed LVEDV, and a normal M/V. Concentric remodeling: characterised by an increased M/V and normal LV mass index. Asymmetric remodeling: similar to concentric remodeling except that in addition there is evidence of asymmetric wall thickening. Concentric Hypertrophy: characterised by an increased M/V and LV mass index. Asymmetric hypertrophy: similar to concentric hypertrophy except that in addition there is evidence of asymmetric wall thickening. Left Ventricular Decompensation: characterised by a dilated left ventricle and normal M/V. The LV mass index may be increased primarily due to LV dilatation. Note no patients fulfilled the criteria for eccentric hypertrophy and so this was replaced by LV decompensation. ↑ increased; ↓ decreased; = normal; ✓present; ✖absent.
