About the HeartFlow FFRCT Analysis

Starting with a standard coronary computed tomography angiogram (CTA), the HeartFlow Analysis leverages algorithms trained using deep learning (a form of AI) and highly trained analysts to create a digital, personalized 3D model of the heart. The HeartFlow Analysis then uses powerful computer algorithms to solve millions of complex equations to simulate blood flow and provides FFRCT values along the coronary arteries. This information is used by physicians in evaluating the impact a blockage may be having on blood flow and determine the optimal course of treatment for each patient. A positive FFRCT value(≤0.80) indicates that a coronary blockage is impeding blood flow to the heart muscle to a degree which may warrant invasive management.

Data demonstrating the safety, efficacy and cost-effectiveness of the HeartFlow Analysis have been published in more than 500 peer-reviewed publications, including long-term data out to five years. The HeartFlow Analysis offers the highest diagnostic performance available from a non-invasive test.1 To date, clinicians around the world have used the HeartFlow Analysis for more than 100,000 patients to aid in the diagnosis of heart disease.
