Intra-Aortic Balloon PumP (IABP) とは?



The concept of counter pulsation in the management of left-ventricular failure was first described by Kontrowitz and Kontrowitz more than 60 years ago [1].

A few years later, in 1962, Moulopoulus et al. [2] introduced the counter pulsation via device inserted into the aorta. Since then the IntraAortic Balloon Pump (IABP) has become a valuable minimally invasive method of augmenting left-ventricular function.

With the IABP in place in the thoracic aorta, inflation of the balloon in diastole and active deflation in systole induces higher perfusion pressures in the brain and the coronary arteries in diastole and unloads the diseased heart by reducing left ventricular afterload in systole.
