WEDGES: Coronary Lesion Preparation With Enhanced Dilatation for Good Expansion of Stent: Assessment of a New Scoring Balloon by Quantitative Stent Enhanced Visualization (WEDGES)
WEDGES: a Prospective, Multi-center Randomized Trial for the Evaluation of Coronary Lesion Preparation With Enhanced Dilatation for Good Expansion of Stent: Assessment of a New Scoring Balloon by Quantitative Stent Enhanced Visualization
Stent under-expansion during percutaneous coronary intervention (PCI) is one of the suboptimal results associated with a higher risk of restenosis and thrombosis. In order to obtain an optimal stent expansion, especially in lesions with calcific or fibrotic plaque, the appropriate lesion preparation before stent implantation is a crucial phase.
For this, different devices are used in everyday practices, including non-compliant balloon (NC), scoring / cutting balloons or rotational atherectomy; however, their effectiveness depends on the experience and skill of the operator. The purpose of this study is to assess the feasibility, efficacy and safety of a novel scoring balloon intended to treat calcific or fibrotic plaque of a coronary lesion

활성 비교기: Conventional 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

실험적: Scoring balloon predilation
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.
