Why the study?
Complications associated with the MitraClip system in high-risk patients with symptomatic severe MR have been recognized, but hemolytic anemia following implantation had not previously been reported.
This case report highlights the rare complication of subacute hemolytic anemia following transcatheter edge-to-edge mitral valve repair with a MitraClip.
Suggests vigilance for hemolytic anemia post-MitraClip; single case leaves open incidence and need for screening.
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.
