Subacute hemolytic anemia after transcatheter edge-to-edge mitral valve repair: A case report

The MitraClip System is extensively used in high-risk patients with symptomatic severe mitral regurgitation (MR). Some studies have identified complications associated with use of the MitraClip. We report the case of a 91-year-old woman with severe MR of a prolapsed posterior commissure. Two weeks after using the MitraClip, she developed hemolytic anemia. She was conservatively treated with blood transfusion and medical treatment; fortunately, her general condition did not deteriorate during the follow-up period. To the best of our knowledge, this is the first report of hemolytic anemia after MitraClip implantation.
