Intra-aortic balloon counterpulsation, also called intra-aortic balloon counterpulsation in English, is a very widely used treatment in critical cardiovascular disease. It is based on the use of a very long vascular pump, which is implanted in the aorta. During cardiac contraction, this pump collapses and creates a siphon effect, sucking blood out of the heart, which reduces the work done by the heart. During diastole, the pump is hitched up and the blood goes to the vital organs of the body, such as the heart and brain, so that the blood supply to the heart and brain system is more adequate. It is mainly used in the interventional treatment of complex coronary heart disease, the interventional treatment of acute myocardial infarction, the transitional treatment of surgery, and even the transitional treatment of heart transplantation or some serious shock patients, which can ensure the life safety of patients.
