Indications: patients with hemodynamic instability or severe LV systolic dysfunction.
1. Severe peripheral vascular disease (PVD) of the aortoiliac and femoral arteries – due to increased risk of lower extremity ischemia.
2. Severe aortic valve insufficiency (AI), because their AI will be worsened by the balloon pump.
Updated definition 2020:
An intra-aortic balloon pump (IABP) is a device used to decrease myocardial oxygen demand and increased oxygen supply to the heart. The balloon inflates during diastole, promoting blood flow through the coronary arteries, and deflates during systole allowing forward flow into the systemic circulation. Contraindications to the placement of an IABP include the following:
- moderate to severe aortic insufficiency
- inability to place the device i.e. peripheral vascular disease
- aortic aneurysm or dissection
- sepsis or bleeding diathesis
- patient refusal
