The present disclosure relates to a therapeutic method for improving the hemodynamics, the overall microcirculation in organs, and the restoration and preservation of deficient endothelial function in a patient, the method includes maintaining blood circulation in the patients veins and arteries and temporarily relieving the heart of its pumping function. Relief may be accomplished by increasing the preload of the right ventricle so as to improve oxygenation of the myocardium and its contractility, reducing and diffusing regular pulsations in the proximity of the aortic root so as to improve the hemodynamics of the left ventricle of the heart, and/or mechanically stimulating the endothelium by shear forces so as to reduce systemic and pulmonary afterload.
