An intra-aortic balloon pump (IABP) is a medical device used to support patients with severe heart conditions. It consists of a balloon catheter inserted into the aorta, the main artery carrying blood from the heart. The balloon inflates and deflates in sync with the heart's rhythm, helping to improve blood flow and reduce the heart's workload. IABPs are often used in critical care settings, particularly for patients experiencing cardiogenic shock or those recovering from heart surgery. By enhancing coronary blood flow and decreasing myocardial oxygen demand, IABPs can stabilize patients and improve their chances of recovery.
