Value of FFR in clinical practice

Area of Science:

• Cardiology
• Interventional Cardiology
• Physiology

Background:

• Coronary artery disease diagnosis often relies on anatomical assessment.
• Determining the functional significance of coronary lesions is crucial for optimal patient management.
• Fractional flow reserve (FFR) provides physiological data beyond anatomical stenosis.

Purpose of the Study:

• To explain the fundamental principles of Fractional Flow Reserve (FFR).
• To highlight the clinical utility of FFR in guiding interventional cardiology decisions.
• To provide an overview of FFR's role in the cardiac catheterization laboratory.

Main Methods:

• Discussion of the physiological basis of FFR measurement.
• Explanation of the methodology for calculating FFR during cardiac catheterization.
• Review of clinical scenarios where FFR is applied.

Main Results:

• FFR quantifies the pressure difference across a coronary stenosis.
• FFR values correlate with myocardial ischemia and predict adverse cardiac events.
• FFR is a reliable indicator of lesion significance.

Conclusions:

• FFR is an essential tool for assessing the physiological significance of coronary lesions.
• The integration of FFR into clinical practice improves decision-making in the cath lab.
• FFR facilitates personalized treatment strategies for patients with coronary artery disease.
