Key result
A single MitraClip implantation in an 87-year-old woman with multiple degenerative mitral regurgitation jets shortened the anterior-posterior annulus diameter and significantly reduced both MR jets.
Why the study?
A mitral annuloplasty-like effect has been shown after MitraClip, but the clinical benefit of this phenomenon was unclear.
Does a single MitraClip implantation reduce multiple degenerative MR jets through an annuloplasty effect in an elderly patient?

Does a single MitraClip implantation reduce multiple degenerative MR jets through an annuloplasty effect in an elderly patient?
A single MitraClip deployment can effectively reduce multiple degenerative MR jets by inducing a mitral annuloplasty-like effect.
Single MitraClip may shorten mitral annulus in multi-jet MR; hypothesis-generating for clinical benefit of this effect.
Background: Previous reports have shown a mitral annuloplasty-like effect after MitraClip, i.e. a shortening of the anterior-posterior diameter of mitral valve annulus. However, the clinical benefit of this phenomenon is unclear. Case summary: An 87-year-old woman with multiple degenerative mitral regurgitation (MR) jets, including a central-medial jet and a lateral jet, underwent MitraClip procedure. After a single clip implantation, anterior-posterior diameter of mitral annulus was shortened and both MR jets were significantly reduced. Discussion: Even in the case of multiple MR jets, a single clip deployment with the MitraClip system may provide an acceptable MR reduction if the clip shows the mitral annuloplasty effect.

Fukutomi et al. (2023) conducted a case report in Multiple degenerative mitral regurgitation (n=1). MitraClip procedure was evaluated on Reduction of MR jets and shortening of anterior-posterior diameter of mitral annulus. A single MitraClip implantation in an 87-year-old woman with multiple degenerative mitral regurgitation jets shortened the anterior-posterior annulus diameter and significantly reduced both MR jets.
