Heart valve mechanical prosthesis: The perfect match until it is not - A case report.

Primary immune thrombocytopenia (ITP), formerly known as idiopathic thrombocytopenia, is defined by a reduced platelet count <50x10 and is clinically manifested through signs and symptoms such as bleeding, ecchymosis and petechiae. Its coexistence with the implantation of the mechanical valves and the necessity of anticoagulation creates an additional risk of bleeding. Although mechanical valves are indispensable in prolonging and improving the quality of life in patients with valvular heart disease, in the context of an additional bleeding risk factor, their presence could represent a threat to life exposing the patient to major complications and leading to death.
