Difficult Cases and Complications from Catheterization Laboratory: MitraClip Therapy in a Patient with Lack of Leaflet Coaptation
In patients with functional mitral regurgitation (MR) due to extreme annulus and/or left ventricle dilation, the valve geometry features required for MitraClip implantation, in particular the coaptation length ≥2 mm and the coaptation depth <11 mm, could be missing. We report the case of a 43-year-old patient with severe ischemic mitral regurgitation and lack of leaflet coaptation mainly due to posterior mitral leaflet retraction, showing step by step the possible pharmacological and mechanical methods to modify the mitral valve apparatus allowing the leaflet grasping using MitraClip device.
