Real-time utilisation of instantaneous wave-Free Ratio: Results of the ADVISE in-practice: an international, multi-centre evaluation of iFR in clinical practice

2014
OBJECTIVES: To evaluate the first experience of real-time instantaneous wave-free ratio (iFR) measurement by clinicians.BACKGROUND: The iFR is a new vasodilator-free index of coronary stenosis severity, calculated as a trans-lesion pressure ratio during a specific period of baseline diastole, when distal resistance is lowest and stable.

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

Journal of Invasive Cardiology
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.Consecutive patients undergoing ...
