Feasibility of Optical Coherence Tomography-Derived Computational Fluid Dynamics in Calcified Vessels to Assess Treatment With Orbital Atherectomy.

A 72-year-old male patient presented with stable angina, and coronary angiography showed a heavily calcified mid left anterior descending coronary artery lesion (diameter stenosis ≈ 75%). Optical coherence tomographic (OCT) assessment (C7-XRsystem, C7 Dragonfly catheter; LightLab Imaging, St. Jude
