					ABSTRACT
					
	Intracoronary physiology is routinely used in setting the indication for 
percutaneous coronary intervention (PCI) but seldom in assessing 
procedural results. This attitude is increasingly challenged by 
accumulated evidence demonstrating the value of post-PCI functional 
assessment in predicting long-term patient outcomes. Besides fractional 
flow reserve, a number of new indexes recently incorporated to clinical 
practice, including nonhyperemic pressure and functional angiographic 
indexes, provide new opportunities for the physiological assessment of 
PCI results. Largely, the benefit of these tools is derived from 
longitudinal analysis of the treated vessel, which allows precise 
identification of the vessel segment accounting for a suboptimal 
functional result and enabling operators to perform accurate PCI 
optimization. In this document the authors review available evidence 
supporting why physiological assessment should be extended to immediate 
post-PCI with the aim of improving patient outcomes. A step-by-step 
guide on how available physiological tools can be used for such purpose 
is provided.
