Post sternotomy support apparatus appropriately positioned, including an intra-aortic balloon pump (IABP) with its metallic tip in the region of the aortopulmonary window. Note the left paraspinal gas, indicating that the balloon is inflated. Mild bibasilar atelectasis, lungs otherwise clear.
From the case:
Intra-aortic balloon pump

CT shows the inflated IABP within the descending thoracic aorta.
Case Discussion
IABPs may be placed to treat cardiogenic shock. The balloon forcibly inflates with helium during diastole, pushing blood into the coronary arteries and arch vessels proximal to the balloon, and pushing blood in the descending aorta distally. Active deflation during systole creates a vacuum effect, decreasing afterload.
