Intraaortic balloon pump
 Discussion of Intraaortic balloon pump
- Intraaortic balloon pumps (IABP) are used to improve coronary artery perfusion.
- When distended in diastole, the balloon causes increased pressure in the proximal aorta, thus improving coronary artery perfusion.
- Forced deflation during systole decreases cardiac afterload, resulting in decreased left ventricular work and oxygen requirements.
- Ideal position for an IABP is just distal to the left subclavian artery.
- If the balloon pump is too proximal in the aorta, occlusion of the brachiocephalic, left carotid, or left subclavian arteries may occur.
- If the catheter is too distal, the celiac, superior mesenteric, or renal arteries may be obstructed.
- Complications of intraaortic balloon pump placement are seen in 8-29% of procedures and include limb ischemia, aortic dissection, mesenteric ischemia, renal insufficiency, neurologic complications, thrombocytopenia, bleeding, and infection.
 Imaging Findings for Intraaortic balloon pump
 Plain film
- At the tip of this catheter is an approximately 1-cm metallic marker that is visible on radiographs or fluoroscopy and is used to ensure proper placement—ideally, just distal to the left subclavian artery.
- Ideally, the tip is positioned approximately 2-4 cm below the level of the aortic arch.
