[Hemolytic anemia in the malfunction of a mitral bioprosthesis]

Valvular cardiac prosthesis have dramatically altered the prognosis of patients with valvular cardiac disease; however, they are not free of complications. Prosthesis disfunction and problems related to anticoagulation are the more common, but hemolytic anemia should also be considered. In this case, hemolytic anemia appears as the major complication of a mitral bioprosthesis; the decision concerning the presentation of this case report rests upon its rarity and peculiar circumstances of appearance. A brief revision of the diagnostic work-up is also made.
