[Thrombosis and thromboembolism in patients with a Björk-Shiley prosthesis].
Thrombosis and thromboembolism are, in addition to left ventricular function, the basic factors which deteriorate the score and long-term prognosis in patients with valvular prostheses. The authors analyze the problem of thrombosis and thromboembolism in 261 patients with Björk-Shiley's prosthesis who were operated during the last five years. The authors consider as the main risk factors in the first place inadequate anticoagulation treatment, the position of the implant in the mitral orifice, the type of valvular implant and atrial fibrillation. The authors present a brief account of successful thrombolysis of a thrombotized Björk-Shiley prosthesis in the mitral orifice, the basic diagnostic procedure when thrombosis of an artificial valve is suspected and possible ways how to reduce the risk of thrombosis and thromboembolism.
