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.
背景
既往报告显示，使用MitraClip后出现类似二尖瓣环成形术的效果，即二尖瓣瓣环前后径缩短。然而，这一现象的临床益处尚不清楚。
病例摘要
一名87岁女性，患有多种退行性二尖瓣反流（MR）束，包括中央内侧束和外侧束，接受了MitraClip手术。植入单个夹子后，二尖瓣瓣环前后径缩短，两个MR束均显著减少。
讨论
即使在存在多个MR束的情况下，如果夹子显示出二尖瓣环成形术的效果，使用MitraClip系统部署单个夹子可能会使MR得到可接受的减少。
