Insights
Fractional flow reserve (FFR) helps identify significant coronary artery blockages. This invasive measurement guides revascularization decisions, improving patient management when noninvasive tests are inconclusive.
Area of Science:
- Cardiology
- Interventional Cardiology
- Physiology
Background:
- Coronary artery disease management often involves revascularization.
- Conventional angiography can overestimate lesion severity, leading to unnecessary interventions.
- Accurate assessment of coronary physiology is crucial for optimal treatment.
Purpose of the Study:
- To review the concept and clinical utility of Fractional Flow Reserve (FFR).
- To discuss the evidence supporting FFR in guiding revascularization decisions.
- To explore future perspectives for FFR application in coronary artery disease.
Main Methods:
- Review of current literature on Fractional Flow Reserve (FFR).
- Analysis of studies comparing FFR diagnostic accuracy with noninvasive modalities.
- Examination of clinical outcome data from studies using FFR-guided treatment strategies.
Main Results:
- FFR is a valuable tool for assessing the hemodynamic significance of coronary lesions.
- European Society of Cardiology guidelines recommend FFR for guiding revascularization when noninvasive data is lacking.
- FFR-guided strategies have demonstrated clinical utility in managing intermediate coronary stenoses.
Conclusions:
- FFR provides critical physiological information beyond anatomical assessment.
- Accurate FFR measurement aids in selecting appropriate patients for revascularization.
- Further research will continue to refine the role of FFR in interventional cardiology.
Abstract:
Revascularization of ischemia-producing coronary lesions is widely used in the management of coronary artery disease. However, some coronary lesions appear significant on the conventional angiogram when they are truly non-flow limiting. For this reason, it is becoming increasingly important to determine the coronary physiology. Fractional flow reserve (FFR) has emerged as a useful tool to determine the lesions that require revascularization. Measurement of FFR during invasive coronary angiography now has a class IA indication from the European Society of Cardiology for identifying hemodynamically significant coronary lesions when noninvasive evidence of myocardial ischemia is unavailable. Current data on FFR can be broadly classified into studies that compare the diagnostic accuracy of FFR measurement compared with other noninvasive modalities and studies that test treatment strategies of patients with intermediate coronary stenoses using a threshold value for FFR and that have clinical outcomes as endpoints. In this review, we will discuss the concept of FFR, current evidence supporting its usage, and future perspectives.
