Abstract
Introduction: Deciding whether to treat coronary lesions in patients with chronic coronary syndrome can be challenging for interventional cardiologists. Traditional angiography-based diagnosis can lead to unnecessary intervention. Fractional Flow Reserve (FFR) measurement helps accurately assess the impact of the lesion in term of hemodynamic factor, leading to an appropriate decision of intervention.
Objective: To study the the outcomes of FFR-guided coronary intervention.
Methods: Cross-sectional descriptive study.
Results: With 50 lesions in 43 patients, there was a mismatch between morphological and functional stenosis in 30% of the lesions. Specifically, 10% of the lesions were morphologically severe but had an FFR > 0,8, while 20% were morphologically moderate but had an FFR ≤ 0,8. FFR helped prevent missing intervention for 27,78% of lesions that were morphologically moderate but functionally significant. FFR also helped avoid unnecessary intervention for 35,72% of morphologically severe lesions that were not functionally significant.
Conclusion: The use of FFR in clinical practice optimizes treatment decisions, ensuring that interventions are performed only when truly necessary, thereby improving treatment effectiveness and minimizing risks for patients.
