Web Seminar: Hemodynamics of Counterpulsation

The Intra-aortic balloon pump (IABP) has been the first-line choice for mechanical circulatory support around the world due to its clinical efficacy, safety profile across a broad range of patient care scenarios, and low cost. IABP therapy is the most widely used nondurable mechanical circulatory support device (MCS), with more than 60,000 implants per year in the United States alone. The primary goals of the IABP are to (1) increase diastolic aortic pressure and augment coronary blood flow, and (2) reduce aortic and left ventricular systolic pressure or afterload. This education offering will provide a review of the physiologic benefits, evaluate patient response, discuss what patients may derive the most benefit and practical technical components to optimize IABP therapy.

After completing the program participants should be able to:

  1. Assess the physiologic effects of Intraaortic Balloon Counterpulsation (IABP) therapy
  2. Understand the clinical utility of  IAB use
  3. Describe the factors that effect IAB catheter performance and benefits of larger-capacity IAB catheters
