Eclipsed Functional Mitral Regurgitation Destabilizing Hypertrophic Cardiomyopathy: An Unusual Case Treated With MitraClip

MitraClip (Abbott Laboratories, Abbott Park, IL) is validated in high-risk patients with severe degenerative mitral regurgitation (MR); however, it is not well established for functional MR in hypertrophic cardiomyopathy (HCM). We share a case of a 68-year-old man with HCM hospitalized for multiple...

description MitraClip (Abbott Laboratories, Abbott Park, IL) is validated in high-risk patients with severe degenerative mitral regurgitation (MR); however, it is not well established for functional MR in hypertrophic cardiomyopathy (HCM). We share a case of a 68-year-old man with HCM hospitalized for multiple incidents of acute pulmonary edema caused by a dynamic MR and successfully treated with the MitraClip device. Novel teaching points emerging from this case are that MRs in HCM can often be explained by mixed mechanisms, and properly identifying the MR mechanism is essential to choose optimal treatment. Furthermore, MitraClip can simultaneously treat MR secondarily to annular dilation and systolic anterior motion.
