IABP
Pronunciation: I-A-B-P
Also written as: IABP — Intra-Aortic Balloon Pump
Mechanical cardiac assist device that inflates and deflates in the aorta to augment coronary perfusion.
Full Definition
The Intra-Aortic Balloon Pump (IABP) is a temporary mechanical circulatory support device used in surgical critical care for patients with cardiogenic shock or high-risk cardiac procedures. The balloon catheter is inserted through the femoral artery and positioned in the descending aorta, where it inflates during diastole to increase coronary perfusion and deflates during systole to reduce afterload. IABP therapy requires careful timing with the cardiac cycle and continuous monitoring for vascular complications.
Usage
Usage note: Pronounced eye-ay-bee-pee, not as a word.
