Mitral regurgitation (MR) with multi-pathogenesis is a common disease in cardiac surgery department. MR can be classified into two categories-primary mitral regurgitation and secondary mitral regurgitation. With the development of cardiac intervention, numerous patients who cannot tolerate open heart surgery for the reason of high risk of surgery receive the treatment of intervention and achieve the favorable endpoint. The technique of transcatheter therapy which could be used to treat MR is comprised of leaflet repair, annuloplasty and implantation of artificial chordae. Comparing to primary mitral regurgitation, surgical effect of secondary mitral regurgitation is not desirable for the reasons of complex pathophysiologic mechanism. Hence, based on the perspective of surgeon, we will introduce the research progress of transcatheter interventional mitral valve repair which is focused on the treatment of primary mitral valve regurgitation and reviewed from three aspects of surgical risks, surgical types and outlook.
