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.
