The 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 that carries 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. This device is often used in cases of heart failure, cardiogenic shock, or during high-risk cardiac surgeries. By enhancing coronary blood flow and decreasing the heart's oxygen demand, the IABP can stabilize patients and improve their chances of recovery.
