Numerical study of hemolysis induced by shear stress at the junction between aorta and ventricular assistance device outflow graft

•Blood flow within aorta involving an outflow graft from a ventricular assistance device is simulated and analyzed for different scenarios.•Both concurrent flows generate recirculations and high shear during diastolic phase.•Hemolysis risks at the junction remain relatively low.•Thrombosis is more prone to occur in case of severe heart failure condition.
