Functional Mitral Regurgitation: Transcatheter Therapy.

ABSTRACT

Mitral regurgitation (MR) is one of the most prevalent types of valvular heart disease and is expected to increase in the next decade. Transcatheter therapies for MR are constantly being developed and studied for use in this population. In this review, the author describes the phenotypes of functional or secondary mitral regurgitation, discusses the potential therapeutic targets for transcatheter intervention, and reviews the results of such technology in the literature.
