Annuloplasty effect of transcatheter edge-to-edge repair with MitraClip system on multiple degenerative mitral regurgitations.

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.
