[Active infective endocarditis with idiopathic thrombocytopenic purpura: a case report].

This is a case report of infective endocarditis with idiopathic thrombocytopenic purpura (ITP). Open heart surgery to the patient with ITP has a problem of perioperative hemorrhage. Usually, treatment for ITP is performed before operation, and platelet transfusion is provided for hemorrhage. However, in our patient, we had to perform emergency operation because of progressive heart failure without treatment of ITP. Emergency operation should be performed without treatment of ITP, not to delay operative timing in such a case of progressive heart failure from active infective endocarditis.
