1. Intra-Aortic Balloon Pumps

2. Intra-Aortic Balloon Pumps
Purpose
The intra-aortic balloon pump consists of a long inflatable balloon 26-28cm in length surrounding the distal end of a centrally placed catheter. It is used in the setting of cardiogenic shock to enhance cardiac function.

Access and Placement
The balloon pump is introduced via the femoral artery and advanced retrograde into the thoracic aorta. The balloon is ideally situated with the tip located just distal to the left subclavian artery at the level of the aortic arch. Such placement ensures maximal augmentation of diastolic pressures in the proximal aorta. Inflation of the balloon during diastole increases diastolic pressure, enhancing perfusion of the coronary arteries and oxygen delivery to the myocardium. Deflation of the balloon during systole creates a vacuum within the vessel lumen, decreasing ventricular afterload and enhancing forward blood flow.
