after repositioning

  • Used in cases of cardiogenic shock or recent cardiac surgery
  • Placed, via a femoral artery, into the descending aorta
  • Balloon inflates during diastole, thereby increasing flow in the coronary arteries and improving cardiac perfusion
  • Small metal rectangle at its tip should be placed within the descending aorta, just distal to the left subclavian artery
    • Placement too proximally within the aorta may diminish flow to the arch vessels
    • Placement too distally will reduce effectiveness, and may occlude visceral (SMA, renal) arteries
