Prosthetic Aortic Valve Thrombosis Detected by Doppler Echocardiography.

Thrombosis of the prosthetic valve is a highly lethal medical emergency that requires immediate diagnosis and prompt therapy. Establishing the diagnosis may be difficult, despite numerous physical, echocardiographic, fluoroscopic, and angiographic signs, which have been described. We report a case of prosthetic aortic valve thrombosis diagnosed by Doppler echocardiography. (ECHOCARDIOGRAPHY, Volume 13, March 1996)
