What is Ratio between Vena Contracta Width and Tricuspid Annular Diameter: Prognostic Value in Secondary Tricuspid Regurgitation about?
## Background: Conventional approaches for the assessment of secondary tricuspid regurgitation (str) severity do not correct for right heart dimensions. the authors hypothesized that str severity can be proportional or disproportional to the dilation of the tricuspid annulus (ta) and investigated the prognostic impact of this novel definition. ## Methods: A total of 334 patients with moderate to severe str and preserved left ventricular systolic function were included. the ratio between vena contracta (vc) width and tricuspid annular diameter was calculated. the cutoff value for vc/ta ratio associated with increased risk for all-cause death was identified using spline-curve analysis. ## Results: The cutoff value of vc/ta ratio associated with a mortality excess was 0.24, and 165 patients (49%) had vc/ta ratios ≥ 0.24. compared with those with vc/ta ratios < 0.24, patients with vc/ta ratios ≥ 0.24 had a higher prevalence of moderate to severe mitral regurgitation, had higher pulmonary pressures, and were more frequently treated with diuretics. during a median follow-up period of 62 months (interquartile range, 28-101 months), 128 patients (38%) died. the cumulative 5-year survival r
