title: Mitral stenosis due to dynamic clip-leaflet interaction during the MitraClip procedure: Case report and review of current knowledge.
abstract: The goal of MitraClip therapy is to achieve mitral regurgitation reduction without iatrogenic creation of clinically significant MS. In some series, up to 35% of patients are left with mild MS. There are many contributors to the final transmitral gradient achieved in patients undergoing MitraClip therapy. Additionally, there are many modalities used for the intraprocedural assessment of MS with no one modality considered to be the benchmark. We herein describe a case which illustrates the dynamic nature of clip-leaflet interaction, and review intraprocedural techniques for invasively and noninvasively assessing MS.
