Late Bioprosthetic Mitral Valve Thrombosis: A Link With Postoperative Heparin-Induced Thrombocytopenia?

The authors report the case of a patient with late bioprosthetic mitral valve thrombosis associated with a history of postoperative heparin-induced thrombocytopenia. The patient successfully underwent mitral valve replacement.
