Fig 1.
CMR feature tracking analysis of right ventricular radial strain in the mid short axis slice in patients with hypertrophic cardiomyopathy with and without left ventricular outflow tract obstruction.
A. Color map of RV radial strain in a patient with LVOTO at baseline (left panel) and at peak (right panel). B. Color map of RV radial strain in a patient without LVOTO at baseline (left panel) and at peak (right panel). C. Curves of RV radial strain in the mid ventricular short axis slice in HCM with (red) and without (blue) LVOTO. CMR—cardiovascular magnetic resonance feature tracking, HCM—hypertrophic cardiomyopathy, LVOTO—left ventricular outflow tract obstruction, RV—right ventricle.
