1. A system for transcatheter aortic valve treatment, comprising:
an arterial access sheath adapted to be introduced into an access site at the left or right carotid artery, or left or right subclavian artery,
wherein the arterial access sheath has a first lumen configured to receive a valve delivery system, the valve delivery system configured to deliver a prosthetic valve into a heart or aorta through the arterial access sheath, the first lumen having a first opening at a proximal end of the arterial access sheath and a distal opening at a distal most end of the arterial access sheath;
wherein the arterial access sheath further has a perfusion lumen with a proximal end and a distal opening and wherein the perfusion lumen has a length such that the distal opening of the perfusion lumen can be positioned in and perfuse an artery when in use;
an elongated body having a shunt lumen, the elongated body configured to fluidly connect an external source of perfusion fluid to the perfusion lumen of the arterial access sheath, wherein the elongated body receives perfusion fluid only from a source of perfusion fluid other than the arterial access sheath; and
the valve delivery system, wherein the valve delivery system fits within the first lumen of the arterial access sheath.
