Coronary Physiology Instantaneous Wave-Free Ratio (iFR) Derived From X-Ray Angiography Using Artificial Intelligence Deep Learning Models: A Pilot Study

Coronary angiography (CAG)-derived physiology methods have been developed in an attempt to simplify and increase the usage of coronary physiology, based mostly on dynamic fluid computational algorithms. We aimed to develop a different approach based on artificial intelligence methods, which has seldom been explored.
