Strut fracture and disc embolization in Bjork-Shiley mitral valve prostheses: diagnosis and management
PK Davis, JL Myers, JL Pennock and BL Thiele
Mechanical failure of the Bjork-Shiley tilting disc prosthesis is a rare
but catastrophic complication of the valve. Several previously reported
cases of major strut fracture with disc embolization led to improvements in
the structure of the prosthesis. A case of minor strut fracture in the
improved convexoconcave model of the Bjork-Shiley mitral valve prosthesis
is described. The literature on mechanical failures in the Bjork-Shiley
mitral valve prosthesis is reviewed, and recommendations for recognition
and management of this problem are made.
