Safety and efficacy of frequency-domain optical coherence tomography in evaluating and treating intermediate coronary lesions

Figure 1 Box plot diagrams comparing reference area, minimum luminal area and % area stenosis parameters obtained from two-dimensional quantitative coronary angiography and frequency-domain optical coherence tomography imaging in the optical coherence tomography-guided percutaneous coronary intervention and optical coherence tomography-guided optimal medical therapy groups. 2D-QCA: Two-dimensional quantitative coronary angiography; FD-OCT: Frequency-domain optical coherence tomography; PCI: Percutaneous coronary intervention; OMT: Optimal medical therapy.

Figure 2 Pie charts comparing outcome at 12 mo between the optical coherence tomography-guided percutaneous coronary intervention and optical coherence tomography-guided optimal medical therapy groups. OCT: Optical coherence tomography; PCI: Percutaneous coronary intervention; OMT: Optimal medical therapy.
