1. An apparatus, comprising:
a cardiac pump comprising a cannula configured to draw blood from a left ventricle of a heart of a subject into an inflow distal section of the cardiac pump, and the cardiac pump configured to release the blood into the aorta of the subject from a plurality of outflow windows in an outflow proximal section of the cardiac pump;
an expandable anchoring device extending along a longitudinal axis, wherein the expandable anchoring device is arranged about a central axis, wherein a distal portion of the expandable anchoring device defines an annulus through which the cardiac pump can be arranged and to which a proximal region of the cardiac pump can be coupled, and wherein a proximal portion of the expandable anchoring device has a conical shape and is configured to circumferentially expand to an unconstrained configuration that has a cross-sectional diameter greater than a diameter of the annulus and thereby engages an inner circumference of the aorta; and
a constraining member arranged over the expandable anchoring device to constrain the expandable anchoring device in a constrained configuration for delivery of the expandable anchoring device;
wherein when the expandable anchoring device is coupled to the cardiac pump and expanded within the aorta, the plurality of outflow windows are positioned distal and upstream of the proximal portion of the expandable anchoring device that is engaged with the inner circumference of the aorta.
