Thrombolytic treatment as first option in recurrent tricuspid prosthetic valve thrombosis and Ebstein's anomaly.

Ebstein's anomaly is the most frequent cause of congenital tricuspid regurgitation. The coexistence of a mechanical heart prosthesis in a low-pressure circuit and poor compliance in the anticoagulant therapy contributed decisively to the appearance of recurrent mechanical heart valve thrombosis in these patients. A 49 years old female patient is reported where thrombolytic therapy with recombinant Streptokinase (TT-rSK) was the first treatment choice in seven recurrent episodes of prosthetic valve thrombosis.
