Figure 1. Flowchart of the study enrollment.
Abbreviations: HF: heart failure; LVEF: left ventricular ejection fraction; DCM: dilated cardiomyopathy; TR: tricuspid regurgitation; TRPG: tricuspid regurgitation pressure gradient; TV: tricuspid valve.
Figure 2. Changes of the tricuspid regurgitation pressure gradient in group 1.
In group 1, the post-implant TRPG was significantly higher than pre-implant TRPG (p < 0.001).
Figure 3. The cumulative incident rate of progressive post-implant tricuspid regurgitation.
The cumulative rate of progressive post-implant TR increased from 1.3% in the first year to 18.4% in the sixth year.
Figure 4. A Kaplan-Meier curve analysis for heart failure hospitalization.
Group 1 (with progressive post-implant tricuspid regurgitation and/or elevated tricuspid regurgitation pressure gradient) had a significantly higher incidence of heart failure hospitalization compared to group 2 (without progressive post-implant tricuspid regurgitation and/or elevated tricuspid regurgitation pressure gradient) (log-rank P < 0.001).
