Background An increasing number of end-stage heart failure patients are being bridged to heart transplant (BTT) with ventricular assist devices (VAD). This is due to a severe shortage of donor hearts. Surgery for VAD explant and heart transplant can

Single-cycle and multiple-cycle frictional-sliding experiments were employed to evaluate the effects of pore fluid environments on yield strength, frictional-sliding dynamics, and gouge production and morphology. Circular right cylinders cored from B
