Journal of Clinical Ultrasound.0091-27511097-0096http://dx.doi.org/10.1002/jcu.23457https://hdl.handle.net/20.500.12491/11618Purpose: For assessing the severity of tricuspid regurgitation (TR), there is no gold standard. We developed a parameter, the right ventricular systolic force ratio-RIVIERA, using the continious wave Doppler analysis of TR and pulsed-wave analysis of the right ventricle outflow tract. We hypothesized that the RIVIERA would facilitate the ability to identify severe TR in clinical settings.Materials and Methods: We obtained data from routine transthoracic echocardiograms. All records reporting no or mild TR (n = 732), moderate TR (n = 584), and severe TR (n = 519) TR were reanalyzed to measure vena contracta (VC) width, TR jet area, effective regurgitant orifice (EROA) derived with the proximal isovelocity surface area method, the RIVIERA, and right-sided chamber volumes.Results: Significant linear trends were demonstrated for right atrial volume index, end-diastolic volume index, RVOT velocity time integral, TR jet area, TR-Vmax, TR-VTI, TR acceleration, VC width, EROA with increasing TR severity. Independent predictors of severe RT included RIVIERA <4.8, VC width =0.7 cm, TR jet area > 10 cm(2), and EROA =0.4 cm(2).Conclusion: The RIVIERA is a feasible, effective, and independent predictor of severe TR that enhances established techniques for estimating TR severity. For clinical decision-making and management, accurate measurement and classification of TR severity are essential. Therefore, it should be thought about include the RIVIERA in the integrative method to assessing TR severity.eninfo:eu-repo/semantics/closedAccessAccelerationDopplerForceRight Ventricle Outflow TractTricuspid RegurgitationVelocity-Time IntegralArticle10.1002/jcu.2345719370007082-s2.0-85152028181Q3WOS:000962183900001Q3
