Figure 3. Evaluation of a non-culprit lesion in non-ST-segment elevation myocardial infarction. Evaluation of a non-culprit lesion in non-ST-segment elevation myocardial infarction. FFR (A) was performed in the non-culprit circumflex artery, yielding a value of 0.84 (not hemodynamically significant). However, OCT revealed a long lipid plaque with TCFA (B, D) and a probable silent plaque rupture site (C). Ongoing studies aim to determine whether such hemodynamically non-significant but high-risk lesions should be stented. FFR: Fractional flow reserve; OCT: optical coherence tomography; TCFA: thin-cap fibroatheroma.
