Division of Cardiology, University Hospitals, Leuven, Belgium.

Recombinant tissue-type plasminogen activator (rt-PA) was administered intravenously to a 64-years old female with thrombotic malfunction of a Björk-Shiley prosthetic tricuspid valve. 150 mg of single-chain rt-PA was infused over 8 hours followed by an additional dose of 50 mg over the next 8 hours. At the end of the first infusion, restoration of normal valve function was demonstrated by fluoroscopic and echo-Doppler examinations. Mild systemic activation of the fibrinolytic system occurred, with a decrease of fibrinogen and alpha 2-antiplasmin to 53% and 33%, respectively, of the preinfusion value at the nadir.

D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010959 Tissue Plasminogen Activator A proteolytic enzyme in the serine protease family found in many tissues which converts PLASMINOGEN to FIBRINOLYSIN. It has fibrin-binding activity and is immunologically different from UROKINASE-TYPE PLASMINOGEN ACTIVATOR. The primary sequence, composed of 527 amino acids, is identical in both the naturally occurring and synthetic proteases.
