Fractional Flow Reserve (FFR)

What Is Fractional Flow Reserve?

Fractional Flow Reserve (FFR) is a specialized measurement performed during cardiac catheterization to assess how much a coronary artery blockage is affecting blood flow to the heart muscle. Unlike imaging alone, FFR evaluates the functional impact of a narrowing, helping cardiologists determine whether it is likely to cause symptoms or increase the risk of future cardiac events.

FFR is especially valuable when the severity of a blockage is unclear, providing objective data to guide treatment recommendations.

How the FFR Procedure Works

During an FFR assessment, a thin pressure-sensing wire is carefully advanced through a catheter into the coronary artery. Measurements are taken before and after the narrowing to evaluate pressure differences and blood flow under controlled conditions.

This real-time data allows the cardiologist to determine whether the blockage is restricting blood flow enough to require intervention, such as angioplasty or stenting, or whether it can be managed safely with medication and monitoring.

When Fractional Flow Reserve May Be Recommended

FFR may be recommended for patients with coronary artery disease when angiography shows moderate narrowing and additional information is needed to guide treatment. It is commonly used in patients with chest pain, abnormal stress test results, or symptoms that suggest reduced blood flow but do not clearly indicate the need for intervention.

By clarifying the functional significance of a blockage, FFR helps avoid unnecessary procedures while ensuring that truly significant lesions are treated appropriately.

Benefits of Fractional Flow Reserve

One of the primary benefits of FFR is its accuracy in guiding treatment decisions. By measuring actual blood flow rather than relying on visual estimates alone, FFR helps ensure that interventions are performed only when they are likely to provide meaningful benefit.

This approach supports safer care, improved outcomes, and more personalized treatment planning for patients with coronary artery disease.
