Ultrasonic evaluation of thrombosis of Bjork-Shiley aortic valve prosthesis
F Orzan, E Garcia, LW Pechacek, RJ Hall and DA Cooley
Recognition of thrombosis of a Bjork-Shiley aortic valve prosthesis 4 years
after insertion in a patient was based upon sudden clinical deterioration,
loss of prosthetic sounds, and development of new stenotic and regurgitant
murmurs. Thrombotic fixation was confirmed by diagnostic alterations on the
echocardiogram. All manifestations reverted to normal after successful
surgical debridement of the prosthesis. Echocardiography is a valuable
noninvasive adjunct in the differential diagnosis of prosthetic valve
malfunction.
