CT-FFR-guided Strategy for In-stent Restenosis

CT-FFR is a type of non-invasive procedure to provide a 3D model of coronary arteries as a way to evaluate the hemodynamic significance of coronary artery lesions. CT-FFR calculates FFR from subject-specific CCTA data using computational fluid dynamics technology. CT-FFR value ≤0.80 is considered hemodynamically significant.

Participants randomized to usual care will be evaluated according to institutional standard practice.
