1. A system for unloading of cardiac preload and afterload, the system comprising:
a cardiac assist device configured to pump blood within a patient to reduce cardiac afterload;
a flow limiting element configured to be positioned at a superior vena cava (SVC) of the patient; and
a controller configured to be coupled to the flow limiting element, the controller configured to cause the flow limiting element to fully occlude the SVC over multiple cardiac cycles to reduce cardiac preload.
