Assessment of Right Ventricular Function by Newer Imaging in Echocardiography in Idiopathic Pulmonary Arterial Hypertension

Figures

Figure 1. Whisker plot diagrams showing distribution of RV longitudinal strain in different WHO functional class at baseline. At baseline, there was no significant interclass difference in mean RV longitudinal strain distribution (P = 0.0781).
Figure 2.
Figure 2. Whisker plot diagrams showing average differences of RV longitudinal strain between non-survivors and survivors groups at baseline and at 6 months. The difference in average RV longitudinal strain between non-survivors and survivors groups neither significant at baseline (P = 0.912) nor at 6 months (P = 0.181).
