At Clemenceau Medical Center in Beirut, Lebanon — affiliated with Johns Hopkins International — a recent case study demonstrated the strong agreement between Keya Medical’s DeepVessel FFR (DVFFR) and invasive fractional flow reserve (FFR) measurements. Led by Dr. Mohamad J. Mansour and his colleagues, the study highlights the role of DVFFR in providing an accurate, non-invasive functional assessment of coronary artery disease (CAD), helping to avoid unnecessary invasive procedures.

Case Summary
A 69-year-old woman presented with acute chest pain.
- CCTA Findings: Mid-LAD intermediate stenosis (50–69%)
- DVFFR Findings: 0.83 (borderline ischemic)
- Invasive FFR Findings: 0.81 (borderline ischemic)
The close match between DVFFR and invasive FFR confirmed the lesion’s minimal functional impact, leading to medical management without stenting. Both modalities ruled out ischemia in other vessels (LCX and RCA), underscoring DVFFR’s value in identifying functionally insignificant lesions.

Clinical Significance
DVFFR provided functional assessment closely aligned with invasive measurements, supporting its role as a safe, efficient, and accurate alternative for evaluating intermediate coronary stenoses. Its use can reduce the need for invasive procedures while ensuring optimal patient care.
