1. Complete debridement of the infective and destructive valve tissue was performed first.
  2. The fresh autologous pericardium was harvested and trimmed to an appropriate size corresponding to the defect of the mitral valve. The patch was attached to the annulus of the leaflet tissues.
  3. Artificial chordae sutures were placed to the edge of the reconstructed pericardium.
  4. Finally, mitral annuloplasty with an artificial annular ring was performed.
