About HeartFlow
HeartFlow is a medical technology company that leverages artificial intelligence (AI) and computational fluid dynamics to provide non-invasive solutions for diagnosing and managing coronary artery disease (CAD). The company’s core offering, the HeartFlow One platform, transforms standard coronary computed tomography angiography (CCTA) images into personalized, dynamic 3D models of a patient’s heart. [1, 11, 14, 15, 16, 21, 24] This platform offers clinicians comprehensive insights into coronary artery anatomy, physiology, and plaque characteristics, aiming to optimize care delivery and achieve the best possible outcomes. [1, 5, 15, 21, 23]
Specifically, the HeartFlow One platform includes FFRCT Analysis, which assesses the impact of arterial narrowings on coronary blood flow; Roadmap Analysis, which assists in identifying the location and severity of stenoses; and Plaque Analysis, which quantifies and characterizes plaque volume and composition to aid in risk stratification. [4, 15, 16, 21, 22, 23] These AI-driven tools are designed to overcome the limitations of traditional non-invasive imaging tests, enabling more accurate and efficient detection of CAD, guiding treatment decisions, and optimizing care pathways without the need for invasive procedures. [1, 11, 14, 15, 20, 23, 24] HeartFlow’s technology has been extensively validated through clinical evidence and peer-reviewed publications, and it is recognized in ACC/AHA Chest Pain Guidelines. [5, 15, 16, 17] The company aims to transform CAD from a leading cause of death into a manageable condition, empowering clinicians with precision tools to improve patient outcomes and personalize treatment journeys.

What Physicians Need to Know
HeartFlow provides physicians with unparalleled clinical clarity and confidence by integrating anatomical and physiological insights from CCTA scans. This enables more precise, personalized treatment plans, from early risk stratification and medical management to optimized PCI planning. The extensive clinical validation (over 600 peer-reviewed publications and ACC/AHA guideline support) and high accuracy (e.g., 95% agreement with IVUS for plaque analysis) empower physicians to make decisive, evidence-based decisions, potentially improving patient outcomes and streamlining care pathways by reducing unnecessary invasive procedures. The instant delivery of quality-reviewed analyses further enhances workflow efficiency.
HeartFlow's solutions are designed for seamless clinical integration, delivering final analyses instantly upon order. They offer support for deployment and configuration of the HeartFlow One software, including integration with existing Picture Archiving and Communication Systems (PACS), Electronic Medical Records (EMR), and other IT solutions to streamline workflows and enhance patient data accessibility.
