Mean RV contour strain for 18 subjects without heart disease (a. d) and 16 subjects with heart failure (b, e). Segmental data are shown for the RV free wall (a, b) and the septum (d, e). (c, f) RV peak contour strain for (c) the RV free wall and (f) the septum demonstrate dysfunction in heart failure patients compared to subjects without heart disease (*p < 0.01). All data shown are mean ± standard deviation.
