Björk-Shiley cardiac Valve Prosthesis with Integral Monostrut

Abstract

In the Monostrut valve, the U shaped wire-form has been replaced by a thicker monolithic projection with no welds. The disc occluder opens to 70 degree instead of 60 degree. This new Björk-Shiley valve prosthesis was implanted in 41 patients between Oct., 1983 and Oct., 1984. There were 3 early deaths not related the prosthesis. There were no late deaths and no mechanical failure. A further study on this new prosthesis is warranted.
