A system for decreasing blood flow that comprises a transesophageal aortic compression balloon, wherein the balloon comprises a body and an expandable section that can cycle between an expanded state and a compressed state. The system further includes a controller for actuating the expandable section between the expanded state and the compressed state according to a predetermined pattern. When the expanded balloon is adjacent a subjects aorta it may at least partially compress a portion of the subjects aorta and decrease blood flow below the point of compression.
