Over 15 years: the advancement of transcatheter mitral valve repair

Paolo Denti et al. Ann Cardiothorac Surg. 2021 Jan.

Abstract

Patients with severe symptomatic mitral regurgitation, if left untreated, have a poor prognosis. In those patients not eligible for mitral valve (MV) surgery, percutaneous repair may improve clinical outcomes. In the past 15 years several devices have been developed to address different MV lesions. This manuscript will review the advancement of transcatheter MV repair through the years, focusing on technologies for which consistent clinical data is available.

Keywords: MV repair; Mitral regurgitation; mitral valve (MV); transcatheter MV repair.
