The standard portion of the procedure includes the angiogram (X-ray pictures of the arteries), FFR (measurement of blood flow in the artery), IVUS and/or OCT (to assess the diameter of the artery and the size of the stent), medications, and all office visits. The research portion of the study requires all imaging studies be performed (NIRS IVUS, OCT, FFR) rather than just one or two of these imaging studies, and the CCTA.
