Clinical Outcomes of Deferred Lesions With Angiographically Insignificant Stenosis But Low Fractional Flow Reserve.

ABSTRACT:

Background

Data are limited regarding outcomes of deferred lesions in patients with angiographically insignificant stenosis but low fractional flow reserve (FFR). We investigated the natural history of angiographically insignificant stenosis with low FFR among patients who underwent routine 3-vessel FFR measurement.

Methods and results

From December 2011 to March 2014, 1136 patients with 3298 vessels underwent routine 3-vessel FFR measurement (3V FFR-FRIENDS study, ClinicalTrials.gov identifier NCT01621438), and this study analyzed the 2-year clinical outcomes of 1024 patients with 2124 lesions with angiographically insignificant stenosis (percentage of diameter stenosis <50%), in which revascularization was deferred. All lesions were classified according to FFR values, usin
