Mitral transcatheter edge-to-edge repair: patient selection, current devices, and clinical outcomes

INTRODUCTION: Over the last two decades, mitral transcatheter edge-to-edge repair (M-TEER) has become a safe and effective therapy for severe mitral regurgitation in patients deemed at high surgical risk. AREAS COVERED: This review aims to encompass the most relevant and updated evidence in the field of M-TEER from its inception, focusing on clinical and anatomical features for proper patient and device selection. EXPERT OPINION: Growing operator experience and device iterations have resulted in improved clinical outcomes and an expansion of the therapy to patients with complex anatomies and clinical scenarios. Future investigations are warranted to determine the best management options and the most suitable device for every patient with MR.
