About Heartflow
Heartflow makes technology used to diagnose and manage coronary artery disease without surgery. Its core offering, the Heartflow Platform, uses artificial intelligence and computational fluid dynamics to build a three-dimensional digital model of a patient's heart from a single coronary CT angiography scan. The platform is best known for turning that one scan into detailed readings of blood flow, arterial narrowing, and plaque volume and makeup, addressing gaps left by conventional non-invasive imaging.
The company positions its platform as a tool for clinicians involved in heart disease diagnosis and ongoing patient care, built around the CCTA scan as its data source rather than requiring additional invasive procedures.
Heartflow was founded in 2007 and is headquartered in Mountain View, California. Its shares are listed on the NASDAQ under the ticker HTFL.
