Echocardiographic diagnosis of a stuck Bjork-Shiley aortic valve prosthesis.
A 55-year-old man who had been asymptomatic after replacement of his aortic valve with a Bjork-Shiley prosthesis, suddenly developed heart failure. The clinical suspicion of prosthetic malfunction was not only confirmed, but specified as being a stuck disc secondary to a large thrombus. Surgical removal of the clot resulted in restoration of normal function and return to the expected findings on echocardiogram. The value of echocardiography in such instances, as well as in routinely following-up patients with prostheses postoperatively, is emphasized.
