Percutaneous mitral valve repair with the MitraClip® (Abbott, Abbott Park, IL) can reduce mitral regurgitation (MR) and improve symptoms and quality of life in patients with severe mitral regurgitation. While this therapy is safe, there have been reports of single leaflet detachment where the MitraClip remains attached only to one leaflet of the mitral valve after deployment. Most of these cases occur within the first month of the procedure but there have been reports of late detachment occurring after this period. This case report describes a patient with severe functional MR who underwent an initial successful MitraClip procedure with implantation of two clips but subsequently developed late detachment of one clip. It also discusses the challenges and feasibility of performing a repeat MitraClip procedure in these patients.
使用MitraClip®（雅培公司，伊利诺伊州雅培公园）进行经皮二尖瓣修复术可减少二尖瓣反流（MR），并改善重度二尖瓣反流患者的症状和生活质量。虽然这种治疗方法是安全的，但有报道称存在单叶瓣脱离的情况，即MitraClip在展开后仅附着于二尖瓣的一个瓣叶。这些病例大多发生在手术的第一个月内，但也有报道称在此之后发生晚期脱离。本病例报告描述了一名患有重度功能性MR的患者，其最初成功接受了植入两个夹子的MitraClip手术，但随后其中一个夹子发生了晚期脱离。报告还讨论了对这些患者进行重复MitraClip手术的挑战和可行性。
