Heartflow's AI-Powered Plaque Analysis Platform Receives FDA Clearance and Expanded Insurance Coverage

Heartflow, a leader in cardiovascular diagnostics, has made significant strides in the development and adoption of its artificial intelligence-powered plaque analysis platform. The company recently secured FDA clearance for an updated version of its algorithm and gained expanded insurance coverage, marking important milestones in its quest to revolutionize coronary artery disease assessment.

FDA Clearance for Enhanced Plaque Detection

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 iteration boasts a 21% improvement in plaque detection compared to its predecessor. This enhancement is based on a substantial dataset of 273,000 patient scans, underlining the robustness of the AI model.

The updated platform offers several key advancements:

• 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 in coronary arteries

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 the product.

The expansion of insurance 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 as it seeks to capitalize on an estimated $1.7 billion market opportunity, with the company projecting that its CCTA plus plaque analysis assessment is applicable to 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. The company reports that personalized readouts have led to changes in treatment approaches for more than half of examined patients, highlighting the platform's potential to significantly impact clinical decision-making.

Looking ahead, Heartflow plans to roll out 3D planning software for percutaneous coronary intervention procedures, including stent placement and other revascularization strategies. This expansion of capabilities demonstrates the company's commitment to advancing cardiovascular care through innovative AI-driven solutions.
