[Thrombolytic therapy with rt-PA of recurrent thrombosis in tricuspid valve prosthesis during pregnancy].

The authors report a case of a woman who had two episodes of a tricuspid Saint-Jude prosthesis thrombosis treated with fibrinolysis using rt-PA, during the fourth month of pregnancy. A first course of thrombolytic therapy was successful with normal valve function despite threatening abortion and uterine bleeding. An early rethrombosis of the prosthetic valve and a failure of a second course of thrombolysis required the interruption of pregnancy with a replacement of the tricuspid valve prosthesis.
