Insights
Functional tests like Fractional Flow Reserve (FFR) and instantaneous wave free ratio (iFR) help identify coronary artery issues. Simpler methods like iFR may improve patient care in cardiac interventions.
Area of Science:
- Cardiovascular medicine
- Interventional cardiology
Background:
- Functional tests complement coronary angiography in diagnosing myocardial blood flow impairment.
- Fractional Flow Reserve (FFR) is recommended for identifying ischemia-related coronary lesions when other evidence is lacking.
Purpose of the Study:
- To introduce and evaluate the instantaneous wave free ratio (iFR) as a simpler alternative to FFR.
- To explore the potential of iFR in enhancing value-based care for coronary interventions.
Main Methods:
- Comparison of iFR with FFR in functional assessments within the catheterization laboratory.
- Evaluation of iFR's requirement for vasodilator administration.
Main Results:
- iFR offers a simpler approach compared to FFR.
- iFR does not require the administration of vasodilators, unlike FFR.
Conclusions:
- The instantaneous wave free ratio (iFR) is a promising, user-friendly alternative to FFR.
- Simpler techniques like iFR have the potential to advance value-based care in coronary interventions.
Abstract:
Functional tests used in the catheterization laboratory have emerged as a very important adjunctive tool to coronary angiography that can identify patients with myocardial blood flow impairment. Fractional Flow Reserve (FFR) measurement is highly recommended for detection of ischemia-related coronary lesion(s) when objective evidence of vessel-related ischemia is not available. Recently, the much simpler instantaneous wave free ratio (iFR) was proposed as an alternative to FFR without the requirement for administration of vasodilators. More user-friendly techniques like iFR might further contribute to value-based care in coronary interventions.
