• W4306827140 abstract "Significant tricuspid regurgitation (TR) is associated with poor outcome and high operative mortality resulting from late presentation. Yet, the optimal timing for intervention is unknown.The purpose of this study was to evaluate the prognostic value of echocardiographic parameters to inform early intervention in asymptomatic TR.Using the Cleveland Clinic echocardiography database 2004 to 2018, the authors identified a consecutive cohort of asymptomatic patients with moderate to severe (3+) or severe (4+) TR. Quantitative TR and right heart parameters were retrospectively determined, and their prognostic utility for all-cause mortality was assessed.In 325 asymptomatic patients (mean age: 67.9 years; 79.4% female) with at least 3+ TR, there were 132 deaths (40.6%), with a median survival time of 9.9 years (95% CI: 7.9-12.7 years). By contrast, the median survival time in an age- and sex-matched cohort of symptomatic TR patients was 4.4 years (95% CI: 2.8-5.9 years). Among all the echocardiographic parameters evaluated, right ventricle free wall strain (RVFWS) and tricuspid regurgitant volume (RVol) were the strongest predictors of mortality in asymptomatic TR. The optimal discriminatory thresholds for these parameters were RVFWS <-19% and RVol >45 mL. The 5-year survival rates by number of risk factors (RF) were 93% (95% CI: 86%-96%), 65% (95% CI: 55%-74%), and 38% (95% CI: 26%-49%) for no RF, 1 RF, and both RFs, respectively. Compared with symptomatic TR, mortality was lower for asymptomatic TR with no RF (HR: 0.10; 95% CI: 0.04-0.29) or 1 RF (HR: 0.29; 95% CI: 0.14-0.58), but similar for asymptomatic TR with both RFs (HR: 1.11; 95% CI: 0.56-2.19).RVFWS and RVol are key prognostic markers that can be serially monitored to inform optimal timing of intervention for severe asymptomatic TR." @default.
