LEFT VENTRICULAR STIFFNESS GRADIENT AND RELATIONSHIP TO MYOCARDIAL STRAIN FROM SINGLE BEAT AND CARDIAC MRI

Myocardial stiffness (b) derived from stress (s) strain (e) relationship provides fundamental assessment of diastolic properties. b gradient (Δb) across LV and relative contribution of local wall thickness (T), curvature (C), s and e to Δb is unknown. Here, we assessed b from base to distal LV and
