[Interventional Mitral valve repair with the MitraClip® procedure. Patient selection criteria].

In current practice the MitraClip® procedure is increasingly being used for patients unsuitable or at high risk for cardiac surgery. This article initially describes the patient groups that are suitable for percutaneous edge-to-edge repair. For this purpose the echocardiographic criteria for severe mitral regurgitation are first characterized and treatment algorithms for patients with primary as well as secondary mitral regurgitation according to current guidelines are illustrated. Basic anatomical requirements for the successful implantation of a MitraClip® are described and a distinction is made between various valve morphologies ranging from optimal to unsuitable anatomical conditions. Finally, three patient groups eligible for percutaneous edge-to-edge repair considering clinical and anatomical criteria are defined: (1) optimal for MitraClip®, (2) MitraClip® could be considered and (3) MitraClip® only in exceptional cases.
