About Heartflow
Heartflow provides a non-invasive solution for coronary artery disease (CAD) assessment using AI to transform standard CT scans into personalized 3D models of the heart and coronary arteries. These models enable clinicians to visualize blood flow, identify blockages, and evaluate the functional significance of lesions without invasive procedures. The platform is designed for cardiologists, radiologists, and healthcare systems seeking to improve diagnostic accuracy and patient outcomes. By integrating advanced computational fluid dynamics with medical imaging, Heartflow delivers detailed insights into coronary artery health, supporting early detection and personalized treatment planning. The technology is particularly valuable in cases where traditional imaging may be inconclusive, offering a safer and more efficient alternative to diagnostic catheterization. Heartflow’s approach aims to reduce unnecessary interventions while ensuring patients receive the most appropriate care for their condition.
