Urokinase was administrated to 9 patients for the thrombolytic treatment of 10 instances of Bjork-Shiley prosthetic valve thrombosis in the mitral position. Patients were diagnosed either from clinical findings or from the maximum opening angle of the prosthetic valve. Before and after administration of urokinase, Doppler echocardiography was performed in all patients. By means of fibrionlytic treatment, the peak velocity of rapid filling into the left ventricle, the peak pressure gradient, the pressure half time and the mean diastolic gradient decreaed, while the effective valve area increased. It was considered that thrombolytic tretment with urokinase is effective for Bjork-Shiley prosthetic valve thrombosis,
