Fractional flow reserve (FFR) is a validated index for assessing coronary stenosis significance. This paper reviews the theory and clinical use of pressure-derived FFR in complex coronary interventions.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
- Physiology
Background:
- Fractional flow reserve (FFR) is a key metric in assessing coronary artery disease.
- Accurate stenosis assessment is crucial for guiding revascularization decisions.
Purpose of the Study:
- To provide an overview of the theoretical underpinnings of coronary pressure-derived FFR.
- To discuss the clinical applicability of FFR in complex coronary interventions.
Main Methods:
- Review of the theoretical basis of FFR calculation.
- Discussion of clinical case examples and guidelines.
Main Results:
- FFR is a well-validated index for physiologic significance of coronary stenosis.
- FFR aids in decision-making for complex coronary interventions.
Conclusions:
- FFR provides essential physiologic information beyond anatomical assessment.
- Understanding FFR theory and application optimizes patient outcomes in interventional cardiology.
