Abstract

A 27-year-old man who received a HeartMate (Thoratec Corporation, USA) left ventricular assist device for progressive heart failure as a bridge to orthotopic heart transplantation is described in the present report. The device failed (mechanical failure) after almost 19 months. The porcine bioprosthetic valves in the inflow and outflow cannulae showed hemorrhage, cusp tears and inflammatory cells, located largely on the inflow valve cusps. The role of the inflammatory cell reaction in the bioprosthetic valve is discussed.
