Abstract Background The MITRA-PRO registry revealed residual mitral regurgitation (MR) to be an important predictor of survival following transcatheter edge-to-edge repair (TEER). Intraprocedural MR assessment using 3D-Vena Contracta Area (VCA) might a feasible tool guide TEER procedures. study aimed assess the impact assessed by 3D-VCA on 1-year mortality. Methods 823 patients with quantification in registry, were included this study. mortality, NYHA classification and major adverse events after TEER. Results Patients trace allocated < 0.1 cm 2 group (27.8%), while ≥ 0.3 (55.4%) was considered as mild (16.8%) relevant MR. One-year mortality significantly lower non-relevant (3D-VCA : 10.5%; 16.0%; 0.3: 24.8%, p = 0.003). An increasing post associated higher At 0.07 increased (1-year 16.5% vs. 7.8%; 0.005) indicating cut-off value for daily practice. Conclusions Residual is Therefore, valuable echocardiographic intraprocedural during achieving improve patient survival. (German Clinical Trials Register: DRKS00012288).
