European Bifurcation Club 2019, EBC 2019 - Barcelona, Spain CORONARY BIFURCATION IMAGING Algorithm when to perform OCT to optimize efficiency can we overcome OCTS limitations Author: Takayuki Okamura, MD, Yamaguchi University Hospital, Japan SUMMARY Pre-procedure OCT assessment in the main vessel provides useful information for bifurcation stenting. However, ostial assessment is fundamentally impossible, a potential disadvantage compared to IVUS, and more contrast media is used. Some ingenuities may overcome them. The biggest advantage of OCT compared to IVUS would be the guidance of the position of the guidewire into the jailed side branch when the side branch dilatation is performed. Further studies whether OCT guidance can improve clinical outcomes would be needed.
