Brief Summary
The ISAR-CALC 2 trial is an investigator-initiated, prospective, randomized, multicenter, assessors-blind, open-label other clinical investigation. The objective of this trial is to investigate final angiographic minimal lumen diameter (MLD) following a strategy of super high-pressure balloon (OPN NC) versus intravascular lithotripsy (IVL) for drug-eluting stent (DES) implantation in severely calcified coronary lesions.

Study Arms (2)
Super high-pressure balloon (OPN NC)
EXPERIMENTALPatients will be treated with a Super High Pressure percutaneous transluminal coronary angioplasty (PTCA) Balloon (OPN NC).
Intravascular lithotripsy (IVL)
EXPERIMENTALPatients will be treated with intravascular lithotripsy (IVL).
Interventions
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.
Eligibility Criteria
You may qualify if:
- Age above 18 years and able to give consent
- Persistent angina despite medical therapy and/or evidence of inducible ischemia
- De-novo lesion in a native coronary artery
- Target reference vessel diameter or intended stent diameter ≥2.50 or ≤4.00 mm by visual estimation
- Severe calcification of the target lesion as determined by visual estimation at coronary angiography
- Unsuccessful lesion preparation with standard non-compliant balloon (\< 30% reduction of baseline diameter stenosis at maximal pressure)
- Written informed consent.
You may not qualify if:
- Target lesion is located in a coronary artery bypass graft
- Target lesion is an in-stent restenosis
- Target lesion is a chronic total occlusion
- Target vessel thrombus
- Limited long-term prognosis due to other comorbid conditions with life expectancy \<12 months
