HeartFlow provides noninvasive diagnostic software that converts CCTA scans into personalized 3D coronary models to simulate blood flow and generate FFRCT, RoadMap, and plaque analyses for clinician decision-making.
<div class="content-intro"><p>Heartflow is a medical technology company advancing the diagnosis and management of coronary artery disease, the #1 cause of death worldwide, using cutting-edge technology. The flagship product—an AI-driven, non-invasive cardiac test supported by the ACC/AHA Chest Pain Guidelines called the Heartflow FFR<sub>CT </sub>Analysis—provides a color-coded, 3D model of a patient’s coronary arteries indicating the impact blockages have on blood flow to the heart. Heartflow is the first AI-driven non-invasive integrated heart care solution across the CCTA pathway that helps clinicians identify stenoses in the coronary arteries (RoadMap™Analysis), assess coronary blood flow (FFR<sub>CT </sub>Analysis), and characterize and quantify coronary atherosclerosis (Plaque Analysis). Our pipeline of products is growing and so is our team; join us in helping to revolutionize precision heartcare.</p> <p>Heartflow is a publicly traded company (HTFL) that has received international recognition for exceptional strides in healthcare innovation, is supported by medical societies around the world, cleared for use in the US, UK, Europe, Japan and Canada, and has been used for more than 500,000 patients worldwide. </p></div><p>The Test Engineer is a hands-on individual contributor on the Test Engineering team, responsible for executing and extending automated test coverage across our regulated SaMD products.
