Intra Aortic Balloon Counterpulsation

Intra Aortic Balloon Counterpulsation

Intra-aortic balloon counterpulsation is a method of temporary mechanical circulatory support that attempts to create more favorable balance of myocardial oxygen supply and demand by using the concepts of systolic unloading and diastolic augmentation. As a consequence, cardiac output, ejection fraction, and coronary perfusion are increased, with a concomitant decrease in left ventricular (LV) wall stress, systemic resistance to LV ejection, and pulmonary capillary wedge pressure. The following review discusses the hemodynamic, clinical, and technical aspects of this important modality for hemodynamic support.
