Preprocedural New York Heart Association Class IV Independently Predicts Mortality After Effective Edge-To-Edge Repair for Primary Mitral Regurgitation

Résumé fourni par la source

Background: In patients with primary mitral regurgitation (MR) (PMR), advanced symptoms classified as New York Heart Association (NYHA) class IV are typically driven by valve deterioration. Transcatheter edge-to-edge repair (mitral valve transcatheter edge-to-edge repair [M-TEER]) reliably achieves effective reduction of mitral regurgitation in high-risk patients. However, whether or not preprocedural NYHA class IV continues to predict outcomes after successful MR reduction remains unclear. Methods: The Outcomes of Patients tReated wIth Mitral Transcatheter Edge-to-edge Repair for Primary Mitral Regurgitation Registry includes PMR patients undergoing M-TEER at 27 international sites between 2009 and 2023. Clinical outcomes were compared between patients in NYHA class IV and those in NYHA class II/III. Results: < 0.001). Conclusions: In PMR, preprocedural NYHA class IV remains an independent predictor of all-cause mortality after effective MR reduction with M-TEER, despite comparable postprocedural results.
