Residual mitral regurgitation grade 2+ after transcatheter edge-to-edge mitral valve repair: Epic fail?
García-Villarreal, Ovidio A
ABSTRACT
Cardiac surgery and interventional cardiology have been pursuing the idea of working together to build a critical process for patients, from which an appraisal is made of long-term procedural outcomes. The sole intention is to avoid therapies which fail to solve the pivotal issues of clinical significance to patient well-being. One such example is the efficacy of transcatheter edge-to-edge mitral valve repair (TEER) in treating the functional mitral regurgitation (FMR), a critical parameter being the presence of post procedural residual, or recurrent mitral regurgitation (MR). The impact that this has in relation to the patient's survival, mortality, and rehospitalization for heart failure rates, should be emphasized before making any special assumptions. Roughly half of patients after TEER experienced post procedural MR 2+ (grade 2/4 by echocardiography) within the first year. In fact, the aforementioned has been greatly ignored in the current guidelines for valvular heart disease, giving a recommendation Class IIa for TEER in FMR. Therefore, whether MR 2+ after TEER influences the patient post procedural outcome in the short and longer terms, requires careful consideration.
