    BackgroundSevere aortic stenosis (AS) and severe tricuspid regurgitation (TR) may coexist. The aim of this study was to determine the change in right ventricular (RV) function and TR after surgical aortic valve replacement combined with tricuspid valve repair (SAVR+TVr), transcatheter aortic valve replacement (TAVR), or conservative management and compare outcomes dependent on RV functional parameters and treatment allocation.MethodsA retrospective analysis was conducted in 147 consecutive patients with severe AS and TR of baseline and 6-month clinical and echocardiographic parameters, including quantitative estimation of RV size and function (end-diastolic and end-systolic areas, tricuspid annular plane systolic excursion, fractional area change, and Tei index).ResultsSAVR+TVr and TAVR were associated with superior reduction in TR jet area after 6 months (P = .01 for time × group interaction) compared with conservative therapy. However, RV function (tricuspid annular plane systolic excursion and stroke volume) improved after TAVR but not after SAVR+TVr (P = .007 and P = .02 for time × group interaction, respectively). Conservative therapy for combined AS and TR was associated with >80% mortality in <4 years. TAVR and SAVR+TVr were associated with improved survival compared with conservative therapy (P < .0001), without significant difference between each other. Quantitative RV functional parameters were associated with poor outcomes, including tricuspid annular plane systolic excursion (P = .002), Tei index (P = .02), and RV fractional area change (P = .03).ConclusionsIn this nonrandomized, retrospective, observational study, SAVR+TVr and TAVR were associated with reductions in TR in patients with severe AS combined with severe TR. Importantly, RV function improved after TAVR but not after SAVR+TVr. Patients with severe AS and TR have a very poor prognosis with conservative therapy. When contemplating invasive procedures, assessment should include quantitative functional RV parameters.Copyright © 2018 American Society of Echocardiography. Published by Elsevier Inc.
