Coronary CT Angiography (cCTA) has an important role in the evaluation of patients with known or suspected coronary artery disease. On occasion it is difficult to determine the clinical importance of a borderline coronary stenosis. Fractional Flow Reserve Computed Tomography (FFRct) HeartFlow analysis provides lesion specific information and helps to aid clinicians in assuring that each patient is on the right treatment pathway by applying physiology to the anatomic findings of the cCTA. Through an advanced, computerized 3D modeling of the coronary arteries, FFRct can potentially eliminate the need for an unnecessary invasive procedure and provide functional data about a coronary stenosis without a stress test. Using static cCTA data and FFRct, we are able to help send patients to the cath lab, but only those who truly need to be there.

Learning Objectives:

  1. Become more familiar with current non-invasive and invasive technologies for diagnosing cardiovascular disease
  2. Understand the relevant benefits and challenges of various cardiac diagnostic testing modalities
  3. Understand how cCTA plays a role in the diagnosis of Coronary Artery Disease
  4. Understand the basic operations of FFRct technology
  5. Understanding cCTA quality and its importance for FFRct

Erin Ernst, BSRT (R) (CT), is a CT Applications Specialist with HeartFlow. Before moving into this role, she worked at the University of Nebraska Medical Center in Omaha as a CT Technologist—scanning everything from trauma to stroke and cardiac. Ernst serves as the board secretary for the Nebraska Society of Radiologic Technologists and on three separate volunteer boards for the American Society of Radiologic Technologists. She recently graduated from the ASRT's Leadership Academy and is currently pursuing her Master's in Healthcare Administration from Briar Cliff University in Sioux City, Iowa. She earned her Bachelor's of Science degree also from Briar Cliff University.
