title: [A case report of thrombosed St. Jude Medical valve in aortic position].
abstract: We report a successful elective re-aortic valve replacement following thrombolysis therapy with Urokinase. Patient was a 56-year-old male with acute heart failure caused by thrombosed St. Jude Medical valve in aortic position. The thrombosed valve occurred 6 years after the implantation due to poor control of anticoagulation therapy. Surgical findings demonstrated the origin of thrombus at the hinge area. Prompt diagnosis and adequate therapy is essential for the thrombosed valve especially in case of mechanical valve. Thrombolysis therapy should be considered if possible, although emergency operation is always indicated.
