Ongoing and future directions in percutaneous treatment of mitral regurgitation.

INTRODUCTION: Mitral regurgitation (MR) is one of the major valvular disease. Although surgical mitral valve (MV) repair is the standard of care for patients with severe MR, an unmet need exists in the management of patients with severe symptomatic MR and high surgical risk. Transcatheter MV therapies are alternative treatment option in such patients with moderate to severe and symptomatic MR. Areas covered: Literatures to direct the reader to important further reading were searched with relevant websites; www.ncbi.nlm.nih.gov/pubmed using search word 'transcatheter mitral intervention'. Expert commentary: A variety of transcatheter techniques have emerged for the percutaneous treatment of MR. We should carefully select one or combination procedure for each patient as an ideal tailor-made transcatheter MV therapy in order to improve the outcomes.
