#Intra aortic balloon pump update

The balloon augments blood flow by volume displacement and pressure changes associated with rapidly injecting helium gas in and out of the balloon chamber, a principle called counterpulsation ( Fig. The device is a flexible catheter with a balloon at the end that sits in the descending aorta just distal to the left subclavian artery. The IABP is a mechanical device that increases blood flow to the coronary arteries during diastole and increases cardiac output during systole. The most common devices used to support these patients until recovery or heart transplantation are an intra-aortic balloon pump ( IABP) or a ventricular assist device ( VAD). Medical therapies for these patients are often limited, and patients may require artificial support to maintain their cardiac output and perfusion to their vital organs while awaiting recovery or definitive surgical treatment. While advances in medical and surgical therapy have been effective in reducing the mortality and morbidity from heart failure, there is a subset of patients who develop severe cardiac failure in the setting of myocardial infarction (MI), following cardiopulmonary bypass, trauma, or advanced cardiomyopathies. The 1-year mortality rate for patients with heart failure is estimated at 20%, while the 5-year mortality rate is estimated to be as high as 59% for men and 45% for women.

Data from the 2010 Centers for Disease Control and Prevention ( CDC) Heart and Stroke Update estimated that approximately 5.8 million people are living with heart failure and approximately 25% have advanced or end-stage heart failure. population has led to a steady rise in the incidence of heart failure. You must lie extremely still in your hospital bed if you have one of these devices in place.Despite the improvement in medical and surgical interventions for cardiovascular disease, the aging U.S. In rare cases, the balloon may overinflate and tear the aorta. An IABP can cause blood clots, which can lead to serious problems, such as a stroke. An IABP can cause an infection in your bloodstream if it is used for too long. This decreases the workload on the heart. This deflation creates extra space in the aorta, allowing the heart to pump out more blood. As your left ventricle is about to pump out blood, the balloon deflates.This inflation helps increase blood flow to the heart and the rest of the body. After your left ventricle has finished contracting, the balloon inflates.The IABP improves the function of only your left ventricle, since this is the chamber that pumps blood into your aorta. This helps your heart pump blood to the body. The balloon on the end of the catheter inflates and deflates with the rhythm of your heart. The IABP is placed inside your aorta, the artery that takes blood from the heart to the rest of the body. The IABP reduces the workload on your heart, allowing your heart to pump more blood. A long-term treatment will likely be needed, such as valve surgery or the insertion of a left ventricular assist device (LVAD). Why is it used?ДЄn IABP might be used to stabilize a person who is in the hospital for acute mitral valve regurgitation or severe heart failure.ДЄn IABP is only used for a short period of time (hours to days). The doctor will use an X-ray machine during this procedure to help accurately position the IABP. He or she then positions the IABP at the center of your aorta, below your heart. Your doctor will numb an area of your leg and thread the IABP through the femoral artery in your leg into your aorta. If you are hospitalized, your doctor may insert an IABP. It is a long, thin tube called a catheter with a balloon on the end of it. This device is inserted into the aorta, the body's largest artery. Topic Overview What is an intra-aortic balloon pump?ДЄn intra-aortic balloon pump (IABP) is a mechanical device that helps the heart pump blood.
