Unlocking the Power
of Coronary CTA

The modern way to diagnose coronary artery disease

The path to diagnosing coronary artery disease (CAD) hasn’t always been clear or reliable.1,2 Until now.

The CT-Flow™ pathway enables physicians to more accurately diagnose patients with suspected CAD by combining two powerful, non-invasive technologies — coronary CTA (CCTA) and the HeartFlow Analysis.1

How does the CT-Flow pathway work?

+

The CT-Flow pathway begins with a CCTA. If the physician sees disease, the CCTA images are sent to HeartFlow, where AI algorithms, computational fluid dynamics and trained analysts create the HeartFlow Analysis. This personalized, color-coded 3-D model of a patient’s coronary arteries provides functional information about each blockage.

How is the CT-Flow pathway different?

To address the current gaps in cardiac diagnostic testing, the CT-Flow pathway:

  • Delivers better per-vessel diagnostic performance than other non-invasive cardiac tests1
  • Provides both anatomical and lesion-specific functional information in a single patient visit
  • Identifies functional disease other non-invasive cardiac tests may overlook1,2
  • Limits invasive testing by allowing physicians to identify patients who can be treated with optimal medical therapy alone3
  • Reduces radiation exposure by up to 50% (compared to a SPECT test)4
  • Leads to better clinical decision-making and improved patient outcomes5

How do patients benefit?

The CT-Flow pathway addresses the current gaps in traditional diagnostic testing – where patients may be misdiagnosed due to inaccurate test results.1,2

Frequently Asked Questions

The CT-Flow pathway provides the highest diagnostic performance available from a non-invasive test to help identify functional disease.1,2 This pathway leads to targeted treatment plans and a more streamlined patient experience.

Within hours, physicians can receive the HeartFlow Analysis, which is available on desktop and mobile.

 

CT-Flow offers a streamlined workflow that reduces unnecessary invasive testing and radiation exposure, and provides more accurate information about their condition compared to other non-invasive cardiac tests.1,2,3,4 The highly visual, color-coded model resonates well with patients and can help increase adherence to treatment plans.

Both CCTA and the HeartFlow Analysis, the two steps of the CT-Flow pathway, are commercially available. The HeartFlow Analysis is FDA cleared and reimbursed by CMS and most major commercial insurers. It’s currently available at more than 400 institutions worldwide — in the United States, United Kingdom, Europe, Canada and Japan — and has been used for more than 100,000 patients to date.
