Recurrent mitral regurgitation with haemolytic anaemia after MitraClip procedure: an autopsy case report.

Single leaflet device attachment and subsequent mechanical haemolysis are rare but fatal complications after TMVr with the MitraClip. Not only degenerative MR but also functional MR may be associated with valve leaflet degeneration. A possibility of mechanical haemolysis should be considered when recurrent MR is observed after TMVr.
