In patients undergoing percutaneous coronary intervention (PCI), intracoronary imaging provides superior information compared to angiography regarding: 1) lesion pathology and need for lesion preparation; 2) appropriate sizing of devices; 3) choice of stent length for complete lesion coverage; 4) post-PCI results such as insufficient expansion or residual disease at stent edges requiring additional treatment; and 5) mechanisms of acute complications including underexpansion, malapposition, edge dissections and stent deformation. Increasing evidence on the effect of imaging guidance in unprotected left main (LM)-PCI shows consistent benefits in the reduction of target lesion revascularisation and mortality. Accordingly, revascularisation guidelines give a class IIa level B ...
