    Coronary optical coherence tomography-derived virtual fractional flow reserve (FFR): anatomy and physiology all-in-one | European Heart Journal

    Most invasive coronary imaging modalities only provide anatomical information from which physiologic significance is inferred. Fractional flow reserve (FFR) and other physiologic indices of lesion severity are more reliable methods to identify physiologically significant lesions. Currently, accomplishing both anatomic and physiologic interrogation of an intermediate coronary stenosis requires the use of multiple devices within the coronary artery. Coronary angiography, optical coherence tomography (OCT), and FFR were performed in a left anterior descending artery harbouring an intermediate lesion. Quantitative coronary angiography (QAngio XA 7.3, Medis, the Netherlands) and OCT analysis were performed (QIvus 3.0, Medis, the Netherlands). Angiography and ...
