198 (18.4%) patients (group 1) experienced progressive post-implant TR and/or elevated TRPG. Group 1 had l larger changes in post-implant TRPG (group 1 vs. group 2; 12.8 ± 9.6 mmHg vs. 1.1 ± 7.6 mmHg; p < 0.001) than group 2 without progressive post-implant TR. Group 1 had a higher incidence of HF hospitalization compared to group 2 (13.6% vs. 4.7%; p < 0.001). Pre-implant TRPG (HR: 1.075; 95% confidence interval (CI): 1.032-1.121; p = 0.001) and post-implant left atrial dimension (HR: 1.076; 95% CI: 1.038-1.114; p < 0.001) were independent predictors of progressive post-implant TR.
