Our take

HeartFlow is a medical equipment manufacturer that uses CT-scanned 3D modelling to assess and analyze a patient's heart and arteries. This non-invasive process can help assess the risks of Coronary Artery Disease (CAD) and strategize the appropriate treatment.

As the world’s leading cause of death, CAD is a worthy target for improved diagnosis and treatment. HeartFlow's approach enables clinicians to deliver more effective treatments faster, making CAD more manageable than ever before.

The company has a long history of awards and innovations, adopting technological advancements as they happen. It successfully launched its IPO in 2021, although a 2022 merger with Longview Acquisitions was called off due to unfavourable market conditions. Despite this, the company remains steadfast, unveiling new technology that ensures better treatment for CAD patients.
