Abstract
- Aim: The aims of this study were: i) to report the prevalence of low-risk patients with degenerative mitral regurgitation (DMR) undergoing mitral transcatheter edge-to-edge repair (M-TEER) in a real-world setting; ii) to evaluate the prognostic significance of EuroSCORE II; iii) to determine whether an optimal M-TEER provides a mortality benefit regardless of EuroSCORE-II.<br />Methods: We analyzed data from the GIOTTO registry that enrolled patients undergoing M-TEER in Italy. We included only patients with DMR. Two groups were defined: patients with EuroSCORE<4% and with EuroSCORE≥4%. A further stratification according to variables included in the EuroSCORE-II was made. Interaction between EuroSCORE-II and optimal procedural success was evaluated. Outcome of interest was all-cause death at 2-year.<br />Results: Among 1659 patients prospectively enrolled in the GIOTTO registry, 657 had DMR, 364 with an EuroSCORE<4% (53%) and 311 with an EuroSCORE≥4% (47%). Patients with lower EuroSCORE were older with less comorbidities. All-cause mortality was higher in patients with EuroSCORE≥ vs <4%. EuroSCORE II ≥ 4% was independently associated with an increased risk of mortality (HR 2.36, 95%CI 1.28-4.38, p = 0.007). Among variables included in the EuroSCORE-II, Left Ventricular Ejection Fraction<35% and systolic Pulmonary Artery Pressure ≥ 50mmhg were independent predictors of clinical outcome. Two-year all-cause death was higher in patients without optimal MR reduction regardless of the calculated surgical risk (p for interaction 0.3).<br />Conclusion: More than half of patients with DMR undergoing M-TEER had a Euroscore<4% with a median age of 81. An optimally successful M-TEER was associated with a lower mortality regardless of EuroSCORE.<br />Competing Interests: Declaration of competing interest M.A., M.M., F.B., C.G., A.G., and C.T. received consultation and speaker fees from Abbott Vascular outside the submitted work.
