One-year outcome of patients submitted to routine fractional flow reserve assessment to determine the need for angioplasty

Abstract

In routine practice, FFR assessment during diagnostic angiography was performed in 6.3%. On the basis of FFR, two-thirds of patients with 'intermediate' lesions were left unrevascularized, with a favourable outcome, when FFR was above 0.80. These data suggest that routine use of FFR during diagnostic catheterization is feasible, safe, and provide help to guide decision making.
