Fractional flow reserve: lessons from PLATFORM and future perspectives

Area of Science:

• Cardiovascular Imaging
• Interventional Cardiology
• Computational Fluid Dynamics

Background:

• Stable coronary artery disease (CAD) management requires identifying patients who benefit most from invasive treatments.
• Ischemia-guided revascularization improves outcomes and cost-effectiveness compared to anatomy-guided approaches.
• Invasive fractional flow reserve (FFR) is the gold standard for assessing lesion-specific ischemia in intermediate lesions.

Purpose of the Study:

• To review the technical aspects, clinical evidence, and limitations of FFR derived from coronary computed tomography angiography (FFR-CT).
• To focus on the PLATFORM Trial's analysis of FFR-CT's effectiveness, clinical outcomes, and resource utilization.
• To present future perspectives for FFR-CT technology.

Main Methods:

• Review of current literature on FFR-CT technology and its clinical applications.
• Analysis of data from the PLATFORM Trial regarding FFR-CT effectiveness and outcomes.
• Discussion of computational fluid dynamics principles applied to cCTA data.

Main Results:

• Coronary computed tomography angiography (cCTA) alone has limitations in specificity for diagnosing significant CAD.
• FFR-CT, derived from cCTA using computational fluid dynamics, enhances diagnostic accuracy by improving positive predictive value and specificity.
• The PLATFORM Trial demonstrated the clinical utility and resource implications of FFR-CT.

Conclusions:

• FFR-CT represents a significant advancement in non-invasive assessment of coronary artery disease.
• This technology has the potential to optimize patient selection for invasive procedures and improve healthcare resource allocation.
• Further research and clinical integration are expected to solidify the role of FFR-CT in CAD management.
