Abstract:
Secondary mitral regurgitation is a frequent valvulopathy due to left ventricle remodeling. Although, its poor prognostic has been established, surgical interventions have shown no substantial benefits in terms of mortality benefit. MitraClip represents a transcatheter alternative. Two randomized trials - MITRA-FR and COAPT comparing the clipping versus optimal medical therapy- have confirmed the feasibility of this intervention in patients with secondary mitral regurgitation. MITRA-FR did not show any significant benefit for the MitraClip group with respect to the composite endpoint (all-cause mortality and rehospitalization for heart failure) at 12 months. On the other hand, COAPT showed a clear superiority of MitraClip in terms of mortality and rehospitalization rates, compared to the conservative treatment alone at 24 months.
