Myocardial Stiffness by Intrinsic Cardiac Elastography in Patients with Amyloidosis: Comparison with Chamber Stiffness and Global Longitudinal Strain

•A novel ultrahigh frame rate, tissue Doppler-based cardiac elastography method was developed. •This method was applied in patients with cardiac amyloidosis. •Findings by elastography correlated with cardiac functional and structural derangements. •These measurements were incremental to known echocardiographic predictors of outcomes. Background The aim of this study was to test the hypothesis that intrinsic cardiac elastography can detect...
