Non-parametric curves (Kaplan–Meier model) of freedom from grade ≥2+ TR. (A) The overall series: in B-TVA patients, the 1-, 5- and 10-year non-parametric estimates of freedom from grade ≥2+ TR were 99.3 (95% CI: 98.8–99.8), 96.9 (95% CI: 95.8–98) and 81.8% (95% CI: 78–85.6), respectively; in R-TVA patients, the 1-, 5- and 10-year non-parametric estimates of freedom from grade ≥2+ TR were 98.1 (95% CI: 96.2–100), 93.6 (95% CI: 90–97.2) and 93.6% (95% CI: 90–97.2), respectively. (B) The PS-matched pairs. The number of patients remaining at risk is reported. B-TVA: tricuspid valve annuloplasty with flexible band; PS: propensity score; R-TVA: tricuspid valve annuloplasty with rigid ring; TR: tricuspid regurgitation.
