Experimental
Conventional balloon predilation
Scoring balloon predilation
the target lesion can be prepared according to standard clinical practice using SC balloons sized 0.8-1:1. Stenting using a drug-eluting stent (DES) is performed and the inflation pressure for delivery is noted, as well as the expected balloon diameter at that pressure. 2 enhanced stent imaging acquisitions (StentBoost or equivalent depending on the X-ray system used), are acquired in 2 orthogonal views. Post dilatation can be performed at operator discretion followed by a final acquisition of 2 similar orthogonal views with enhanced stent imaging. Intravascular imaging is left to the operator's discretion and is encouraged
the target lesion must be prepared with a scoring balloon (SC) inflated 3 times at nominal pressure. To allow the scoring balloon to cross the lesion, it might be necessary to predilate with a small compliant balloon. The size of the scoring balloon to be used for is based on the size of the vessel. Stenting using a DES is performed and the inflation pressure for delivery is noted, as well as the expected balloon diameter at that pressure. 2 enhanced stent imaging acquisitions (StentBoost or equivalent depending on the X-ray system used), are acquired in 2 orthogonal views. Post dilatation can be performed at operator discretion followed by a final acquisition of 2 similar orthogonal views with enhanced stent imaging. Intravascular imaging is left to the operator's discretion and is encouraged
