ComparIson of Strategies to PrepAre SeveRely CALCified Coronary Lesions 2

"Strategy of super high-pressure balloon angioplasty after unsuccessful lesion preparation with conventional NC balloon angioplasty.~Optical coherence tomography (OCT) imaging will be performed after lesion preparation with OPN balloon. Optional additional pre-dilatation with OPN/standard NC balloon is permitted at the operator´s discretion. Following lesion preparation, stenting will be performed in the same setting using a latest-generation everolimus-eluting stent (XIENCE; Abbott Vascular, Chicago, IL, USA). Optional post-dilatation with OPN balloon or standard NC balloon is permitted at the operator´s discretion."

"Strategy of IVL after unsuccessful lesion preparation with conventional NC balloon angioplasty.~Optical coherence tomography (OCT) imaging will be performed after lesion preparation with IVL balloon. Optional additional pre-dilatation with standard NC balloon is permitted at the operator´s discretion. Following lesion preparation, stenting will be performed in the same setting using a latest-generation everolimus-eluting stent (XIENCE; Abbott Vascular, Chicago, IL, USA). Optional post-dilatation with standard NC balloon is permitted at the operator´s discretion."
