Advanced innovations leverage HeartFlow’s core AI technology and are critical additions to HeartFlow’s product portfolio for delivering complete cardiac care
REDWOOD CITY, Calif., Dec. 13, 2021 (GLOBE NEWSWIRE) -- HeartFlow, Inc., the leader in revolutionizing precision heart care, today announced it has submitted a 510k premarket application to the U.S. Food and Drug Administration (FDA) to add advanced anatomic assessment and plaque evaluation to the HeartFlow FFRct Analysis. The PreRead anatomic assessment will help identify the presence and location of narrowings or stenoses in the coronary arteries based on coronary computed tomography (CT) scans. The HeartFlow Plaque technology will provide plaque volume and characterize the type of plaque present. By adding the anatomic assessment and plaque evaluation to the physiological information currently provided by the HeartFlow Analysis, physicians will gain a more comprehensive understanding of a patient’s coronary disease burden and support efficient risk stratification of patients who may be at high risk of death from a heart attack.
“HeartFlow is committed to becoming an indispensable partner to physicians in delivering precision heart care by providing a broad portfolio of game-changing innovations that leverages our core deep learning technology,” said John H. Stevens, MD, President, CEO and Co-Founder, HeartFlow. “The FDA submission is an important step towards delivering a solution that we believe supports complete cardiovascular care by providing clinicians with advanced insights about anatomy, physiology and plaque for their patients with coronary artery disease.”
PreRead is designed to provide a rich anatomic assessment of each coronary CT that, when considered by physicians in conjunction with other patient clinical information, helps physicians to quickly identify where coronary disease is present and understand the severity of the narrowing. The PreRead assessment highlights areas of modeled stenosis greater than
The PreRead assessment is intended to support clinical workflow efficiency, diagnostic accuracy and CT reader consistency as measured by repeatability and reproducibility. In an internal study, the PreRead assessment was
In addition, the HeartFlow Plaque feature is based on a fully automated deep-learning (a form of AI) algorithm for characterizing and quantifying plaque. In an internal study, the HeartFlow Plaque technology was found to be more reliable than expert CT readers in identifying different types of plaque and quantifying total plaque volume.2
About the HeartFlow FFRct Analysis
Starting with a standard coronary CT scan, the HeartFlow Analysis leverages algorithms trained using deep learning 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 to 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.3 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.
About HeartFlow
HeartFlow is the leader in revolutionizing precision heart care, uniquely combining human ingenuity with advanced technology. HeartFlow’s non-invasive HeartFlow FFRct Analysis leverages artificial intelligence to create a personalized three-dimensional model of the heart. Clinicians can use this model to evaluate the impact a blockage has on blood flow and determine the best treatment for patients. HeartFlow’s technology is reflective of our Silicon Valley roots and incorporates over two decades of scientific evidence with the latest advances in artificial intelligence. The HeartFlow FFRct Analysis is commercially available in the United States, UK, Canada, Europe and Japan. For more information, visit www.heartflow.com.
