Abstract:
Bioprosthetic valves have a lower thrombogenicity than mechanical valves, thus long-term systemic anticoagulation can be avoided. Herein, we present an extremely rare case of fibrin thrombus formation on tissue valve, which was observed during the second operation 2 years after the initial operation by chance. This report gives us a word of caution regarding the thrombus formation on the bioprosthetic valves that could be unaware of the presence for the long term.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...
