Predictors of Residual Severe Tricuspid Regurgitation After Transcatheter Mitral Valve Repair

BackgroundSevere tricuspid regurgitation (TR) may persist after a mitral transcatheter edge-to-edge repair (M-TEER) and is associated with worsened clinical outcomes survival. It unclear which patients concomitant (MR) TR will have reduction M-TEER. The aim of this study was to identify the predictors residual (TEER).MethodsData were collected from Northwell TEER registry, prospectively maintained mandatory database including 4 high-volume aortic valve replacement/TEER centers. Transthoracic echocardiograms, both pre-TEER post-TEER, evaluated. Univariate multivariate logistic regression analyses performed severe Significant defined as in grade by at least 1+ moderate (2+) or less 1 month.ResultsOf 479 who underwent M-TEER, 107 MR/TR included. Successful MR occurred 89 (84%) significant 45 (42%). On univariate analysis, only right atrial area unsuccessful model, predictor variable for ≥3+ M-TEER.ConclusionsIn TR, isolated M-TEER occurs ∼40% patients. independent reduction. Other echocardiographic variables (including pulmonary hypertension, ventricular function, annular dilation, fibrillation, presence cardiac implantable electrical device) not TR. Inability predict highlights importance establishing therapies should factor heart-team discussions.
