Cleerly ISCHEMIA vs FFRct
AI Verdict
Choose Cleerly ISCHEMIA if…
Choose Cleerly ISCHEMIA if your clinical focus requires a detailed, vessel-level assessment of ischemia likelihood combined with comprehensive coronary plaque characterization (volume, type, and location). This tool is ideal for physicians seeking a deeper understanding of both the functional likelihood of ischemia and the underlying plaque morphology to inform personalized diagnosis and treatment strategies.
View Cleerly ISCHEMIA →Choose FFRct if…
Choose FFRct if your primary goal is to non-invasively determine the functional significance of coronary artery stenoses by precisely quantifying blood flow (FFRct values) using computational fluid dynamics. This tool is particularly well-suited for guiding revascularization decisions, providing a clear physiological assessment to determine the necessity of intervention.
View FFRct →When choosing between Cleerly ISCHEMIA and HeartFlow FFRct Analysis, physicians should consider their primary diagnostic focus and workflow preferences. Both tools leverage AI and CCTA scans to assess coronary artery disease non-invasively, but they offer distinct strengths. Cleerly ISCHEMIA excels at providing a comprehensive, vessel-level assessment of ischemia likelihood, coupled with detailed coronary plaque characterization and stenosis severity. It generates interactive web-based reports and 3D models, making it suitable for physicians who prioritize a detailed understanding of both plaque morphology and its potential functional impact.
HeartFlow FFRct Analysis, on the other hand, specializes in creating personalized 3D models to analyze blood flow and provide specific FFRct values, directly addressing the physiological significance of coronary narrowings. This tool is particularly beneficial for physicians who need a clear, quantitative assessment of blood flow to guide revascularization decisions. The key practical difference lies in their output: Cleerly ISCHEMIA offers a broader view of plaque and ischemia likelihood, while HeartFlow FFRct provides a direct, computational fluid dynamics-based assessment of blood flow restriction.
Therefore, a physician primarily focused on understanding the extent and characteristics of coronary plaque alongside ischemia risk might lean towards Cleerly ISCHEMIA. Conversely, a physician whose priority is a precise, non-invasive physiological assessment of blood flow to inform interventional strategies would likely find HeartFlow FFRct Analysis more aligned with their needs.

Usability
TieBoth Cleerly ISCHEMIA and HeartFlow FFRct offer interactive web-based platforms for viewing results, including 3D models of coronary arteries. Cleerly highlights integration with PowerScribe, while HeartFlow mentions integration with PACS and HL7, indicating both prioritize seamless workflow integration and user experience.
Clinical Value
FFRctWhile Cleerly ISCHEMIA demonstrates strong diagnostic accuracy and prognostic utility, particularly in plaque characterization and ischemia detection, HeartFlow FFRct has a more extensive body of evidence from large-scale, real-world studies (e.g., FISH&CHIPS with over 90,000 patients) demonstrating significant reductions in cardiovascular mortality and unnecessary invasive procedures. This broad, long-term impact on patient outcomes and healthcare efficiency gives HeartFlow an edge in overall clinical value.
Pricing & Value
FFRctHeartFlow FFRct offers greater transparency with a published CMS payment rate of $1,017 (2025) and claims broad payer coverage (99%), indicating established reimbursement pathways. Furthermore, studies have demonstrated its cost-effectiveness by reducing unnecessary invasive procedures and generating healthcare savings.
Enterprise Readiness
FFRctBoth tools meet essential regulatory and security requirements (FDA clearance, HIPAA compliance, BAA). However, HeartFlow FFRct demonstrates a more extensive track record of enterprise adoption, having been implemented in over 1,400 institutions globally, and offers broader integration capabilities with PACS and HL7.
Innovation
Cleerly ISCHEMIAWhile HeartFlow pioneered FFRct using computational fluid dynamics, Cleerly ISCHEMIA offers a distinct innovation by providing a comprehensive '3-in-1 approach' to assess atherosclerosis, stenosis, and ischemia, with detailed coronary plaque characterization (volume, type, and location). This focus on plaque morphology, in addition to functional assessment, provides a more holistic and potentially prognostic view of coronary artery disease.
