Advances in coronary physiology: Update for 2017

Abstract

Invasive coronary physiology is a key instrument in decision-making for the interventional cardiologist. Fractional flow reserve has been well validated in chronic stable coronary artery disease and its practical applications are expanding into other clinical situations including acute coronary syndrome, severe aortic stenosis, and post percutaneous coronary intervention. Instantaneous free ratio is a resting index used to assess severity of an intracoronary stenosis. This review will cover some of the most recent developments and controversies in invasive coronary physiology.
