BACKGROUND: Fractional flow reserve (FFR) is an accepted standard to detect the functional significance of coronary stenoses. Recent trials suggest that revascularization of moderate coronary stenoses can be safely deferred if the FFR is > or = 0.75 and FFR can be used to guide therapy in multivessel disease.
AIM: In a cohort of patients with moderate angiographic coronary disease, we sought to examine the influence of FFR on lesion revascularization and the impact of multivessel FFR assessment on revascularization strategy.
METHODS AND RESULTS: Patients with FFR measurements taken between April 2005 to October 2007 were included. Out of 300 cases performed in this time, 264 patients were included. Patients were 62 +/- 11 years and 1.3 +/- 0.54 vessels were examined per case. 92.7% of lesions with a FFR < 0.75 underwent revascularizati on an d 93% of lesions with a FFR > or = 0.75 had intervention deferred. FFR was 0.71 +/- 0.07 in the revascularization group (9 coronary artery bypass graft surgery, 64 percutaneous coronary interventions) and 0.86 +/- 0.06 in the deferred group (p < 0.001). Overall, 75% of patients avoided revascularization of at least one vessel on the basis of the FFR.
CONCLUSIONS: Measurement of FFR is clinically useful with a high impact on clinical decision-making in the catheterization laboratory. FFR can be used to reclassify patients with multivessel stenoses, reducing the need for revascularization in the majority of cases.
