PROSTHETIC heart valve replacement has become routine surgical procedure in the treatment of advanced cases of valvular heart disease. One of the most popular prostheses in current use is the Björk-Shiley low-profile disk valve. The valve consists of a free-floating pyrolite disk contained in a polytefcovered alloy cage. The popularity of the valve stems from the ability of the disk to tilt in the direction of blood flow permitting a central, nearly laminar flow pattern that decreases turbulence and subsequent trauma to RBCs. Recent five-year follow-up data have demonstrated the durability of this valve and a low level of hemolysis.1 Although initial reports also suggested a low thrombogenic potential,2 recent reports have described massive thrombosis of the valve, with fixation of the disk.2-9
