Fractional Flow Reserve or Optical Coherence Tomography to Guide Management of Angiographically-Intermediate Coronary Stenosis: A Single-Center Trial
Background Fractional flow reserve (FFR) and optical coherence tomography (OCT) may help both in assessment of angiographically-intermediate coronary lesions (AICL) and in percutaneous coronary interventions (PCI) optimization. Objectives: To compare OCT-guidance and FFR-guidance in patients with AICL in a single-center, prospective, 1:1 randomized trial (acronym: FORZA, NCT01824030 ). Methods Patients with AICL were randomized to FFR or OCT. In the FFR arm, PCI was performed if FFR was ≤0.80. In the OCT arm, PCI was performed if area stenosis was ≥75% or 50%-75% with minimal lumen area <2.5 mm 2 or plaque rupture. Angina (evaluated by Seattle ...
