    Abstract:
    BACKGROUND: Tricuspid regurgitation (TR) is associated with an increased mortality. Previous studies have analyzed predictors of TR progression and the clinical impact of baseline TR. However, there is a lack of evidence regarding the natural history of TR: the pattern of change and clinical impact of progression. OBJECTIVES: The authors sought to evaluate predictors of TR progression and assess the prognostic impact of TR progression. METHODS: A total of 1,843 patients with at least moderate TR were prospectively followed up with consecutive echocardiographic studies and/or clinical evaluation. All patients with less than a 2-year follow-up were excluded. Clinical and echocardiographic features, hospitalizations for heart failure, and cardiovascular death and interventions were recorded to assess their impact in TR progression. RESULTS: At a median 2.3-year follow-up, 19% of patients experienced progression. Patients with baseline moderate TR presented a rate progression of 4.9%, 10.1%, and 24.8% 1 year, 2 years, and 3 years, respectively. Older age (HR: 1.03), lower body mass index (HR: 0.95), chronic kidney disease (HR: 1.55), worse NYHA functional class (HR: 1.52), and right ventricle dilation (HR: 1.33) were independently associated with TR progression. TR progression was associated with an increase in chamber dilation as well as a decrease in ventriculoarterial coupling and in left ventricle ejection fraction (P < 0.001). TR progression was associated with an increased cardiovascular mortality and hospitalizations for heart failure (P < 0.001). CONCLUSIONS: Marked individual variability in TR progression hindered accurate follow-up. In addition, TR progression was a determinant for survival regardless of initial TR severity.
