Figure 2.
Kaplan-Meier survival curves according to the tricuspid regurgitant jet velocity
The survival rate was significantly higher among patients with a tricuspid regurgitant jet velocity of <2.5 m/s (indicating normal pulmonary artery pressure) than among those with a tricuspid regurgitant jet velocity of at least 2.5 m/s (P < 0.001). Because patients were enrolled over a 20-month period, the first patients enrolled were followed for the entire time. Thus, the number of patients at risk at the time of each death is shown for both groups. (Figure and caption reproduced with permission from [8]. Copyright © 2004 Massachusetts Medical Society.
