Utility of fractional flow reserve to guide revascularization in patients with acute coronary syndrome without ST segment elevation

Abstract

Fractional flow reserve is the gold standard for evaluating the functional severity of an epicardial coronary stenosis. Coronary physiology-guided revascularization has been shown to be useful in stable heart disease, but also in acute coronary syndrome. We present the case of a 58 year-old patient with acute coronary syndrome, who presented two angiographically significant stenosis. We decided to perform revascularization guided by coronary physiology. Using fractional flow reserve, the need to revascularize only one of the lesions was determined, leading to a change in therapeutic behavior that exemplifies the virtue of having coronary physiology tools for decision-making.
