Heartflow Advances Coronary Plaque Analysis with FDA Clearance and Expanded Insurance Coverage

Heartflow, a leader in cardiovascular diagnostics, has made significant strides in coronary plaque analysis technology, securing FDA clearance for an updated algorithm and gaining coverage from major insurers. These developments mark a pivotal moment in the company's growth and the broader field of cardiac imaging.

FDA Clearance for Enhanced Plaque Analysis Algorithm

Heartflow has received 510(k) clearance from the U.S. Food and Drug Administration for an updated version of its plaque analysis algorithm. The new technology demonstrates a 21% improvement in plaque detection compared to its predecessor. This advancement is underpinned by data from 273,000 patients, showcasing the company's commitment to large-scale clinical validation.

The updated platform offers several key enhancements:

• 3D color-coded visualization of plaque type, volume, and distribution
• Improved alignment with intravascular ultrasound imaging, matching 95% of the time
• Enhanced ability to quantify plaque blockages based on their characteristics

John Farquhar, CEO of Heartflow, emphasized the importance of these improvements, stating, "Heartflow Analyses give clinicians a view of coronary plaque by type and impact on blood flow with FFRCT that's key to informing management strategies."

Expanded Insurance Coverage and Market Potential

In tandem with the FDA clearance, Heartflow announced significant progress in insurance coverage for its plaque analysis product. Cigna, a major private insurer, will begin covering the software across its commercial and Medicare Advantage plans starting October 1, 2025. This follows UnitedHealthcare's decision in July to update its policies for coverage of the plaque analysis product.

The expanded coverage aligns with updated cardiac imaging guidelines from radiology benefit manager EviCore, set to take effect in early October. These developments are crucial for Heartflow's market penetration, as the company estimates a potential $1.7 billion market opportunity, applicable to approximately 5.5 million patients.

Clinical Impact and Future Developments

Registry studies have linked treatment changes informed by Heartflow's algorithm to reductions in LDL cholesterol. More than half of examined patients have seen changes in their treatment approaches based on the personalized readouts provided by the AI-driven analysis.

Looking ahead, Heartflow plans to expand its offerings with 3D planning software for percutaneous coronary intervention procedures, including stent placement and other revascularization strategies. This aligns with the company's focus on leveraging artificial intelligence to analyze coronary CT angiograms (CCTAs) and optimize medical treatment strategies.

The recent developments come on the heels of Heartflow's successful initial public offering, which raised approximately $364 million. As the company continues to innovate and expand its market presence, it remains positioned at the forefront of AI-driven cardiovascular diagnostics.
