ABSTRACT
AIM:
Tricuspid regurgitation secondary to heart failure (HF) is common with considerable impact on survival and hospitalization rates. Currently, insights into epidemiology, impact, and treatment of secondary tricuspid regurgitation (sTR) across the entire HF spectrum are lacking, yet are necessary for healthcare decision-making. METHODS ANDRESULTS:
This population-based study included data from 13 469 patients with HF and sTR from the Viennese community over a 10-year period. The primary outcome was long-term mortality. Overall, HF with preserved ejection fraction was the most frequent (57%, n = 7733) HF subtype and the burden of comorbidities was high. Severe sTR was present in 1514 patients (11%), most common among patients with HF with reduced ejection fraction (20%, n = 496). Mortality of patients with sTR was higher than expected survival of sex- and age-matched community and independent of HF subtype (moderate sTR hazard ratio [HR] 6.32, 95% confidence interval [CI] 5.88-6.80, p < 0.001; severe sTR HR 9.04; 95% CI 8.27-9.87, p < 0.001). In comparison to HF and no/mild sTR patients, mortality increased for moderate sTR (HR 1.58, 95% CI 1.48-1.69, p < 0.001) and for severe sTR (HR 2.19, 95% CI 2.01-2.38, p < 0.001). This effect prevailed after multivariate adjustment and was similar across all HF subtypes. In subgroup analysis, severe sTR mortality risk was more pronounced in younger patients (<70 years). Moderate and severe sTR were rarely treated (3%, n = 147), despite availability of state-of-the-art facilities and universal health care.CONCLUSION:
Secondary tricuspid regurgitation is frequent, increasing with age and associated with excess mortality independent of HF subtype. Nevertheless, sTR is rarely treated surgically or percutaneously. With the projected increase in HF prevalence and population ageing, the data suggest a major burden for healthcare systems that needs to be adequately addressed. Low-risk transcatheter treatment options may provide a suitable alternative.Key words
