The FDA created an expert panel to make recommendations by which patients should be recommended for prophylactic valve The overall risk of major thrombotic occlusion ranges from 1% to 8%. 1 Karp et al. estimated that the cumulative likelihood of thrombotic occlusion of Bjork-Shiley valve for aortic, mitral, and combination mitral and aortic levels is 3%, 13%, and 13%, respectively. 2 The obstruction of prosthetic valve may be caused by thrombi formation, pannus

Bjork Shiley Monostrut Aortic Model ABMS chromium cobalt alloy heart valve Pfizer, Inc. Cincinnati, ?goto= His surgeon, Dr. Earle B. Kay, hand-stitched the mechanical aortic heart valve replacement used on Baker. The valve was half-moon in style. When the heart pumped blood toward it, the pressure folded the leaflets apart.
