Abstract:
We describe a patient at high surgical risk who was successfully treated with a MitraClip (Abbott Vascular, Menlo Park, CA) without transmitral gradient. She received corticosteroid therapy for systemic lupus erythematosus, and progressive mitral stenosis developed late after MitraClip implantation. It gradually increased and reached 23 mm Hg at 28 months after the procedure; during the same period, her dose of prednisone had to be increased owing to lupus flare. Systemic inflammatory disease has the potential to result in mitral valve inflammation and fibrosis, ultimately causing thickening of the tissue bridge and worsening of the mitral valve obstruction. Preprocedural counseling regarding durability may help in this population.
