Prosthetic Valve Thrombosis by poor anti-coagulation

  • Poor anticoagulant therapy is a major cause of prosthetic valve thrombosis. The young patient previously operated for mitral valve replacement with mechanical bileaflet prosthesis had to undergo reoperation in urgency for problems related to its oral anticoagulant therapy causing the block of one of the two leaflets by thrombosis.

     

    Despite the progress of the monitoring of oral anticoagulant therapy, still today, we see these serious, sometimes lethal, episodes that leave us doubtful. Is still valid the combination 'young patient - mechanical prosthesis' and 'elderly patient - biological prosthesis'?
    Anticoagulation is too risky for a young patient? What do you think?
