Fusion of 3D QCA and IVUS/OCT
TL;DR: A new and robust three-dimensional segmentation and registration approach is presented and validated that provides the interventional cardiologist with detailed information about vessel size and plaque size at every position along the vessel of interest, making this a suitable tool during the actual intervention.

Diagnostic accuracy of quantitative flow ratio for assessment of coronary stenosis significance from a single angiographic view: A novel method based on bifurcation fractal law
TL;DR: In this article, an artificial intelligence algorithm was proposed for automatic delineation of lumen contours of major epicardial coronary arteries including their side branches, and a stepdown reference diameter function was reconstructed based on the Murray bifurcation fractal law and used for QFR computation.

TL;DR: OFR was superior than QFR, and much better than conventional morphological parameters in determining physiological significance of coronary stenosis, and the diagnostic performance of OFR was not influenced by presence of prior myocardial infarction or implanted stents.
