Fig. 5

Relationship between RV systolic dysfunction and RV-ECV. Right ventricular ejection fraction (RVEF) and RV extracellular volume fraction (RV-ECV) are each divided into three groups, and the distribution of RV-ECV for different RVEF groups is shown. There is a significant correlation between RVEF and RV-ECV (r = −0.75; p = 0.001)
