Prospective, multicenter, international, no-randomized, single-arm, investigator-initiated study, enrolling up to 200 patients with intermediate to severe coronary stenosis (30-90% diameter stenosis) in patients presenting with NST-ACS requiring coronary angiography assessment.~Patients will receive ad-hoc OCT evaluation of the target vessels and offline 3D-angio-based FFR evaluation.~The primary study parameter is the association between 3D-angio-based FFR values and OCT detected minimum luminal area pre- and post-PCI
This trial is designed to associate angiography-based fractional flow reserve (3D-angio-based FFR) values with optical coherence tomography findings in pre- and post-percutaneous coronary intervention in patients with non-ST segment elevation acute coronary syndromes.
