Secondary tricuspid regurgitation: more than a mere bystander

Secondary tricuspid regurgitation (sTR) is a common echocardiographic finding in patients with heart failure. However, insights into epidemiology, impact, and treatment of sTR across the entire heart failure (HF) spectrum are lacking, yet are necessary for informed healthcare decision-making. This population-based study included data from 13 469 patients with HF and sTR from the Viennese community over a 10-year period. Severe sTR was most prevalent in patients with reduced ejection fraction and was associated with excess mortality in all heart failure subtypes. Patients with mild sTR already had a significantly impaired survival in comparison to an age- and sex-matched community independent of the underlying HF subtype. Despite high mortality rates and availability of state-of-the- art facilities, sTR was 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.
