**8. Strain imaging sublayers in aortic stenosis**

Sublayer strain analysis may add additional information in the characterization of LV function in patients with aortic stenosis. The following studies address this issue:


AS severity than subepicardial longitudinal strain while correlations between circumferential and radial strain and AS severity are weak [24].

• Compared with normal controls, severe aortic stenosis patients have impaired strain in all three layers of the LV myocardium [25].
