Abstract: The intraaortic balloon pump (IABP) is the single most effective and widely used device for temporary mechanical assistance of the failing heart. Although the principles underlying IABP function are simple, various biologic factors often determine its performance in a particularly complicated way. We briefly describe the basic disciplines of counterpulsation by IABP and the induced hemodynamic changes while clarifying the biologic mechanisms that play a crucial role in the modification of IABP acute hemodynami… Show more

“…Patients must have some level of left ventricular function and electrical stability for an IABP to be effective, as any increase in cardiac output is dependent on the work of the heart itself. Optimal hemodynamic effect from the IABP is dependent on several factors, including the balloon's position in the aorta, the blood displacement volume, the balloon diameter in relation to aortic diameter, the timing of balloon inflation in diastole and deflation in systole, and the patient's own heart rate, blood pressure and vascular resistance [44].…”

“…Intra-aortic balloon pumps (IABPs) have a limited role in maintaining haemodynamic stability in the setting of VT and low cardiac output, 25 and have not been shown to improve procedural outcomes. Percutaneous LVADs allow for end-organ perfusion during long periods of tachycardia.…”

“…Counterpulsation therapy also decreases the native heart rate by 10% [15], and may reduce the left ventricular end diastolic volume by 10-15% [20]. The hemodynamic benefits of counterpulsation support also translate into improved metabolic function and often assist in recovery of end organ function [15]. Counterpulsation therapy improves the cardiac energy balance by increasing the oxygen supply to the myocardium through increased coronary perfusion [21,22] and by reducing myocardial oxygen consumption through a decrease in afterload and left ventricular work [15].…”

“…Cardiac output and stroke volume have been found to increase by up to 20% [13,19]. Counterpulsation therapy also decreases the native heart rate by 10% [15], and may reduce the left ventricular end diastolic volume by 10-15% [20]. The hemodynamic benefits of counterpulsation support also translate into improved metabolic function and often assist in recovery of end organ function [15].…”
