Comparative evaluation of disk- and trileaflet valves in left-ventricular assist devices (LVAD)

Two identical LVADs were equipped with different types of heart valve prostheses (Björk-Shiley disk and PU-valves) and tested in two simultaneous calf experiments for 28 days each. Noise levels, accelerations of the pump housing and thrombus formation were higher for the mechanical valve pump.
