Predictors and outcomes of ischemia-driven target lesion revascularization in deferred lesion based on fractional flow reserve: a multi-center retrospective cohort study.

ABSTRACT:

Background

Fractional flow reserve (FFR) has become the gold standard for diagnosing ischemia in angiographically intermediate epicardial coronary artery stenosis. This study investigated the clinical outcomes and predictors of revascularization deferral based on FFR.

Methods

In this retrospective cohort study, we assessed 474 lesions (440 patients) where revascularization was deferred based on the FFR value. Minimum lumen diameter and %-diameter stenosis were measured. Calcification was graded as none, mild, moderate, or heavy. The synergy between percutaneous coronary intervention with taxus and cardiac surgery (SYNTAX) score I was also determined. The primary outcome was ischemia-driven target lesion revascularization (TLR) in deferred lesions within 3 years. Patients wer
