You can't live without a heart because your heart pumps the blood around your body in circulation and if you didn't have a heart you would die because there would be nothing to pump your blood around you. <~ that's my theory :)

You need a heart, whether natural or synthetic, to keep the blood moving. Without the blood moving, no O2 would get to the cells. O2 is needed for basic functionality, therefore, you would die.
