NCT05072730

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.

Outcome Measures

Primary Outcomes (1)

  • Final angiographic minimal lumen diameter

    The primary outcome measure of the trial is the final angiographic minimal lumen diameter as assessed by angiographic core laboratory.

    Intraprocedural.

Secondary Outcomes (8)

  • Angiographic Success

    Intraprocedural.

  • Procedural Success

    During index hospitalization, assessed up to 30 days.

  • Strategy Success

    Intraprocedural.

  • Acute lumen gain

    Intraprocedural.

  • Complementary lesion preparation

    Intraprocedural.

  • +3 more secondary outcomes

Study Arms (2)

Super high-pressure balloon (OPN NC)

EXPERIMENTAL

Patients will be treated with a Super High Pressure percutaneous transluminal coronary angioplasty (PTCA) Balloon (OPN NC).

Device: Super High Pressure Balloon (OPN NC)

Intravascular lithotripsy (IVL)

EXPERIMENTAL

Patients will be treated with intravascular lithotripsy (IVL).

Device: 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.

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

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
