Activity Description

Coronary artery disease is the leading cause of death in men and women in the United States. The instantaneous wave-free ratio (IFR) can be used to determine whether or not coronary lesions that are visualized angiographically should undergo percutaneous intervention. Utilization of the IFR will hopefully eliminate unnecessary invasive procedures and lead to better patient outcomes. This activity describes the instantaneous wave-free ratio and its use in the cardiac catheterization lab to determine the hemodynamic significance of coronary lesions. This activity highlights the role of the interprofessional team in caring for patients with percutaneous coronary intervention candidates.

Target Audience

This activity has been designed to meet the educational needs of physicians.

Learning Objectives

At the conclusion of this activity, the learner will be better able to:

  • Describe the technical aspects of the instantaneous wave-free ratio (IFR).
  • Explain how the instantaneous wave-free ratio is used in the management of coronary artery disease.
  • Identify instantaneous wave-free ratio values at which coronary lesions are determined to be hemodynamically unstable and therefore should undergo percutaneous intervention.
