The important role of the one-dimensional aortic model as a boundary condition for the reduced cardiac model is highlighted comparing the output of the uncoupled cardiac model (blue line) and the fully coupled model (black line) settings, with a focus on the presence of the dicrotic notch in the aortic pressure curve. From left to right we depict the blood flow coming from the aortic valve, the aortic pressure (\(P_{\text {ar}}\)) and the pressure-volume loops in the left ventricle
