Figure 3 and Central Illustration:

The primary endpoint: incidence of right heart failure within 6 months of surgery. This graph compares the incidence of right heart failure between each group. It also compares the fraction of subjects with moderate, severe, or severe acute RHF in each group. There was no significant difference in RHF incidence between the TVS (46.9%) and No TVS (50%) group (p = 0.81) and the distribution of RHF severity was similar as well.
