Aortic Stenosis with Severe Tricuspid Regurgitation: Comparative Study between Conservative Transcatheter Aortic Valve Replacement and Surgical Aortic Valve Replacement Combined With Tricuspid Repair

摘要

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 andP?=?.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?
