Abstract: Between 1984, and 1992, we observed 8 patients with an obstructed St. Jude Medical (SJM) valve. Of these, 1 had an obstructed SJM valve in the aortic position, 3 in the mitral position, and 4 in the tricuspid position. Diagnosis of obstruction of the SJM valve was made by cineradiography combined with echocardiography in all 8 patients. Restriction or absence of movement of the leaflet of the SJM valve was observed by cineradiography in all of the 8 patients. Normal range of leaflet mobility of the SJM valve w… Show more

“…On the other hand, successful thrombolytic therapy was first described by Luluaga and colleagues (17) in a patient with obstructed prosthetic valve in the tricuspid position. Since then, the efficacy of thrombolytic therapy with either streptokinase, urokinase, or heparin has been demonstrated (5,14,16,18,19). A report (16) that summarized over two hundred published reports that investigated left‐sided prosthetic valve thrombolytic therapy indicated an initial success rate of 82%, an overall thromboembolism rate of 12%, stroke rate of 5% to 10%, mortality rate of 6%, major bleeding complication rate of 5%, and recurrent thrombosis rate of 11%.…”

“…Accordingly, early diagnosis and treatment with t‐PA are essential for the management of patients with prosthetic valve malfunction. The combination of Doppler echocardiography and cineradiography should be used for the diagnosis so as not to overlook prosthetic valve malfunction especially when the patients are asymptomatic (5,10).…”
